EXAIR Digital Flow Meters

This blog is about the costs of compressed air and how to use it more efficiently. How can you determine the costs of your compressed air? The first step you’ll need to take is to put a number to how much compressed air you are currently using. In order to do that you’ll need a measurement tool such as the EXAIR Digital Flowmeter.

The Digital Flowmeter is available from stock for use on Schedule 40 pipe with sizes ranging from ½”-4” I.D. Sizes up to 8” for Schedule 40 and ¾”-4” for copper pipe are also available. Metric sizes are also available for 25mm, 40mm, 50mm, 63mm, 76mm, and 101mm. With a digital readout display, it’s easy to accurately monitor your compressed air usage throughout the facility. Creating a baseline of your usage will allow you to understand your compressed air demand, identify costly leaks, and replace inefficient air products.

The Digital Flowmeter installs in minutes with help from a drill guide and locating fixture to assist in mounting the Digital Flowmeter to the pipe. Two flow sensing probes are inserted into the drilled holes in the pipe. The meter then seals to the pipe once tightened. There is no need to cut, weld, or do any calibration once it is installed. With blocking rings also available, installation can be permanent or temporary. Below is a easy to follow video on how to install EXAIR’s Digital Flow Meter!


The newest addition to this product line is the Digital Flowmeter with wireless capability. Using a ZigBee® mesh network protocol, data is transmitted to an Ethernet connected gateway. This allows you to mount the Digital Flowmeter in areas that you may not be able to easily access and wirelessly monitor and graph the usage with the EXAIR Logger software. 


Wireless output gives you the freedom to track air usage data from any computer!

In addition to communicating wirelessly with the gateway, the Digital Flowmeters can “piggyback” off of each other to extend their range. Each meter has a range of 100’. Using multiple Digital Flowmeters within the same ZigBee® mesh network, data can be passed from meter to meter to extend the distance over which the meters can operate. These can be installed on each major leg of your compressed air system to continuously monitor usage throughout the facility.

If you’d rather go with a hard-wired data collection method, the Digital Flowmeter is also available with a USB Data Logger. Simply remove the Data Logger from the Digital Flowmeter and connect it to the USB port of your computer. The data can then be viewed directly in the accompanying software or exported into Microsoft Excel.


Add a Data Logger for easy Value Tracking
Two special flow meter options we now offer are the Pressure Sensing Digital Flowmeters, and the Hot Tap Digital Flowmeters!

Pressure Sensing Digital Flowmeters help by generating a pressure and consumption profile of a system can help to pinpoint energy wasters such as timer-based drains that are dumping every hour versus level based drains that only open when needed. Hot Tap Digital Flowmeters offer a way to install a flow meter on a pipe that is currently under pressure. It uses a series of valves and mufflers to maintain a safe working environment for the installer.

Conserve Precious Liquids in Non-Pressurized Systems with 1/8 NPT Siphon Fed No Drip Nozzle

 EXAIR’s new 1/8 NPT No Drip Siphon Fed Air Atomizing Spray Nozzles provide consistent and even flow of non-pressurized liquid for applications like marking, lubricating, rinsing, cooling, quenching, wetting (moistening), dust control and humidification. The intelligent design of this Siphon Fed spray nozzle allows for the absence of liquid pressure and in turn, uses gravity fed liquids or lifted liquids from a siphon height of 36 inches (91cm) with the added benefit of positively stopping liquid flow when compressed air is shut off.

         Post spray drips waste precious resources such as expensive coatings, chemicals or water, and unwanted drips can ruin product function on sealing or mating surfaces as well as ruin the appearance of painted or coated finishes. EXAIR’s No Drip Atomizing Nozzles are ideal for these situations where no post-spray drip is permissible. When the compressed air supply is shut off, the no drip nozzle positively seals off the flow of liquid eliminating the possibility of drips.

          EXAIR's No Drip Siphon Fed Atomizing Nozzles are available in round and flat fan liquid patterns. The volume of liquid flow depends on either the gravity or suction height coupled with air pressure. All of EXAIR’s spray nozzles, which include nozzles for pressure fed applications, are composed of 303 stainless steel adding durability and corrosion resistance.  They are available with 1/8, 1/4 or 1/2 NPT inlets with a variety of styles, flow rates and liquid patterns. Mounting brackets are also available for easy installation in specific areas on product lines. They are CE compliant and conflict mineral free.

Save Money by Installing Super Air Knives on Converting Machine !

 

Our Vivekengineers often works with the customers to create a customized solution that best serves the  application. Recently our principal Exair had the pleasure of working with a customer who wanted a better solution on their tissue paper converting machine. What they currently had was too loud, too inefficient, and they knew there was a better way.

The machine was an old rewinder used to convert webs of tissue paper ranging from 99-115” in width. Installed on the old machine was a 115” drilled pipe with 1/16” drilled holes spaced out every ½” along the length of the pipe. This was using a substantial amount of compressed air and was significantly louder than they would’ve liked. They purchased a new machine that had an EXAIR Super Air Knife already installed and working great, so they reached out to Exair for some help.

The customer conducted some time studies to determine exactly how much air this application required. The air blast ran for 500 seconds per hour, equating to 8.3min/hr of air usage. The operation runs 24/7, but with time spent doing changeovers the actual run time is closer to 20hrs.

20hrs x 8.2min = 166 min/day of air usage

166min x 365 = 60,590 min per year

A 1/16” unpolished, drilled hole will consume 2.58 SCFM at a pressure of 60 PSIG. With a total of 228 holes across the full pipe, this is quite a bit of compressed air.

2.58 SCFM x 228 = 588 SCFM of compressed air

588 x 60,590 min = 35,626,920 SCF

Considering the lightweight nature of the material, we recommended that the customer use our .001” shim to cut the flow from Exair Super Air Knives to their minimum. Exair recommended the Model 110054-.001 and Model 110060-.001. At 60 PSIG, a Super Air Knife with .001 shim installed will consume 1.15 SCFM/inch of knife length.

114 x 1.15 SCFM = 131 SCFM of compressed air

131 x 60,590 min = 7,937,290 SCF

Installing the Super Air Knives with .001” shim reduced their air consumption by 77% for a total air savings of 27,689,630 SCF each year. But, what does this mean in terms of money? Really Exair super Air knife does a good amount of saving.

In just one year, on this one single machine, this customer was able to save a good amount of money  per year. These knives quickly pay for themselves, then begin to contribute to your bottom line. All of this in addition to lowering the sound level and providing a safer working environment for their operators.

If you have areas in your facility that are using air inefficiently, Contact a Vivek Engineers Application Engineer.

Exair Heavy Duty Line Vac Solves Alumina Spillage Problem

 

The image below shows spillage of small alumina particles at an aluminum manufacturing plant. This customer needed a method to vacuum the spilled material and return it to the main hopper.  The ideal solution needed to be compact, simple, and provide repeatable results.  All of these are key aspects of EXAIR Line Vacs, so our principal  began discussing application variables to make a solution recommendation.



Spilled alumina material which needs to be vacuumed and returned to the main hopper
.

Whenever Exair team considers Line Vac applications they always explore the following variables:

  •      Bulk density of the material
  •      Size of the material
  •      Conveyance height
  •      Conveyance distance
  •      Required conveyance rate
  •      Available compressed air supply
The spilled alumina in this application has a bulk density of 1.1 g/cm³ (~68.7 pounds/ft³) which needs to be conveyed to a height of 3.3m (~11ft.).  The conveyance rate is not mandated, but the alumina particles are rather small in diameter and the customer wanted to move as much material as possible in as little time as possible.  Compressed air is readily available at proper pressures and flows, so Exair team was left to determine whether a Line Vac could be a viable solution.  Fortunately Exair team has found success in transferring alumina with our Line Vacs in multiple applications before, so Exair team was confident they could find a solution here as well.

The height of this application is 3308mm (~11ft.) – an easy conveyance height for an EXAIR Line Vac.
After exploring the specifics of this application Exair team determined the best solution to be the 2” Heavy Duty Line Vac model 150200.  The 150200 Heavy Duty Line Vac can easily move the alumina to a height of 3.3m at an estimated conveyance rate of 11kg/minute (25 pounds/minute).  There are no moving parts to wear out, which means little to no maintenance and reliable performance each time the Line Vac is used.

EXAIR Heavy Duty Dry Vac For Tough and Abrasive Materials

Naturally, spring is the time of year that we roll up our sleeves and do some of the deep-cleaning we’ve been putting off all winter. So EXAIR has an entire line of Industrial Housekeeping Products that will get your shop tidied up for spring. With no moving parts to wear out and no electrical requirement, these products are Built to Last. For applications requiring you to vacuum harsh or abrasive materials, look no further than EXAIR’s Heavy Duty Dry Vac.

Electrically powered vacuums or shop vacuums are not designed to be operated in a rugged industrial environment. Filters clog, motors wear out, and you find yourself frequently replacing them. EXAIR’s Heavy Duty Dry Vac has NO moving parts to wear out, doesn’t require maintenance, and needs nothing but a source of compressed air to operate. A static resistant hose also prevents painful shocks when working with dry, dusty materials.

The vacuum generator is constructed of a hardened steel alloy designed to be resistant to abrasion and delivers a powerful vacuum level of -60” H2O at 80 PSIG. The lever lock drum lid fits any open top 30, 55, or 110 gallon drum. Moving the system from one drum to another can be done quickly, allowing you to keep different materials separate for recycling. Recycling companies will pay a premium for pre-sorted materials, allowing you to get more out of your otherwise scrap material. It can be used with any open head steel, fiber, or plastic drum in good condition.

If you don’t have a spare drum available, not to worry! EXAIR also sells a Premium Heavy Duty Dry Vac System that will include either a 30, 55, or 110 gallon drum and dolly.

You wouldn’t use a hammer to try and drive in a screw, so don’t try and force a shop vac or electric vacuum to deal with these harsh materials. Get yourself the right tool for the job and give an EXAIR Vac a try.

EXAIR’s Industrial Housekeeping Wet Vacs: The Reliable Alternative to Electric Vacuums


Exair 
manufactures a variety of Industrial Housekeeping pneumatic vacuum systems for a range of applications with dry or wet materials. We have systems suitable for use with dry materials only, wet materials only, as well as one capable of handling both wet and dry. For the purposes of this blog, I’m going to focus on EXAIR’s systems designed for use with liquids.

The Reversible Drum Vac is a compressed air operated vacuum system designed to quickly attach to any closed head 30, 55, or 110 gallon steel drum. The high-powered vacuum allows you to fill a 55 gallon drum in less than two minutes. With the simple turn of a knob, the stainless steel pump quickly empties the drum as well.

For thicker more viscous liquids (up to 1400 cP) or for when the application requires lifting the liquid from below-grade sumps, our High Lift Reversible Drum Vac is the best option. Operating in the same manner as the Standard Reversible Drum Vac, the High Lift RDV provides the extra power you need to move liquids from below grade work areas, sumps, or tanks up to 15’ deep. Both the Reversible Drum Vac and High Lift Reversible Drum Vac are offered in a variety of different systems both with and without the drum included.

Another system designed to be used with liquids is the EXAIR Chip Trapper. The Chip Trapper solves one of the most dreaded tasks in any machine shop: cleaning out the CNC coolant sumps. Over time, chips and shavings can make their way up into the coolant lines resulting in a clog. The coolant flow slows down or stops entirely, resulting in premature wear of expensive cutting tools, imperfections in the parts, or unacceptable product finish. When this occurs, if it is even noticed right away, the machine has to be stopped and valuable production time must be spent identifying the location of the clog and removing it. Another problem, one anyone working around CNC machines can attest to, is the rancid coolant smell that is a result of bacteria building up in the stagnant cutting fluid. Regularly cleaning this oil can reduce this smell, prevent premature tool wear or costly shutdowns, as well as extend the overall life of your coolant.


Using either a standard or High Lift Reversible Drum Vac to provide the vacuum source, the Chip Trapper and High Lift Chip Trapper are capable of filling or emptying a 55 gallon drum in less than two minutes. It is able to pick up both the liquid coolant as well as any chips or shavings that are suspended in the coolant. The liquid is forced through a filter bag inside of the drum which contains any solid materials while allowing the coolant to filter out into the drum. Switching the knob on the Reversible Drum Vac and the directional flow valve to empty will allow the clean coolant to be pumped back out of the drum and reused.

The Chip Trapper is available in either 30, 55, or 110 gallon systems. It’ll also come with (2) 5 micron filter bags, other filter bags are also available ranging from 1 micron up to 200 micron filtration. Using a simple detergent, the filter bags can be washed out, cleaned, and reused multiple times. With no motors or impellers to clog or wear out, as well as no electricity requirement or shock hazard.

If you’re looking for a system that can handle both wet and dry materials, look no further than the EasySwitch Wet-Dry Vac. The EasySwitch is designed to handle the toughest of industrial cleanup jobs with ease. Available with a standard or HEPA certified filter for dry material, the system quickly and easily converts from vacuum mode to dry mode. Simply lift the latch and remove the filter element when vacuuming liquids. When you’re done, just place the filter insert into the lid and you’re ready to vacuum your dry materials.

Using only compressed air, EXAIR’s Industrial Housekeeping vacuums require no electricity. Without electricity and moving parts to wear out, there is no concern for failed parts, motor failure, or personnel safety associated with the use of electric vacuums in wet environments.
If you’re tired of replacing electric shop vacuums, Exair has the solution you need. Feel free to contact us and we’ll be happy to help you select the best system for your application.

Why Is Ambient Air Entrainment Needed For Pneumatic Conveyance?


When attempting to convey material pneumatically it can sometimes not work as one may hope. This could be due to the lack of ambient air entrainment to generate the vacuum flow which lifts the material away and moves the material. The video above gives a brief example of this.

If you would like to discuss pneumatic conveying products or processes, please contact us in below address. EXAIR’s Line Vac air operated conveyors are a great solution for manual “bucket and ladder” applications, hopper loading, scrap conveyance, media recovery and more!
