Super Air Knife for Blowing And Cleaning

Exair’s Compressed Air products   provide solution for Industrial Automation  for various applications in small  and big factories. One of our customers uses  the 18” super Air knife for  blowing and cleaning  water and dust particles from fruits. 

They had a serious problem relating to their fruit drying and cleaning purpose. So they contacted us. Our application engineer visited their site and determine a solution  to their problem .  Earlier they were doing this work by  the electric fans ,but it was time taking and not so effective as they couldn’t clean the dust properly. As per his consideration we provided them a 18” Super Air knife. Now they are satisfied by using EXAIR’s Super Air Knife.

What You Don't Know Can Kill You!

Did you know that it's dangerous to block a typical commercial nozzle with your hand or other body part? According to the Occupational Safety and Health Administration (OSHA), any air hose, open pipe, or tube with an outlet pressure greater than 30 PSIG could potentially injure or even kill someone who blocks the opening with a body part (OSHA CFR 1910.242(b)). The dead-ended pressure buildup could force air bubbles into a worker's bloodstream and block critical blood flow. EXAIR's engineered Air Nozzles are designed to prevent dead-ending at any pressure. >> Tell Me More

Are You Blowing Away Money With Your Current Blowoff Operation?

Many commercial nozzles ignore efficiency in order to try and create additional blowoff force. While this may be useful in the short term, it can ending up costing you a lot of money over the life of that nozzle! For example, a typical 1/8" open pipe blowoff at 80 PSIG will use 70 SCFM of air. EXAIR's equivalent 1/8 NPT Model 1102 Mini Super Air Nozzle will use 10 SCFM at 80 PSIG. In other words, after using EXAIR's engineered nozzle over one year of a 40 hour/week operation, you could save about Rs 1,26,000.00 in compressed air production and that's just by replacing one nozzle! >> Tell Me More

In addition, the reduced air use of an EXAIR engineered nozzle also means that less noise is produced. When a blowoff operation is upgraded with an EXAIR Air Nozzle, noise is reduced by 10 dBA on average! >> Tell Me More

Full-Flow Air Knife

EXAIR’s Full-Flow Air Knife is a cheapest & energy competent way to clean, dry or cool parts, webs or conveyors. Full-Flow Air knives operate by entraining the surrounding air along with the compressed air utilizing the “Coanda” effect to produce high flow, high velocity curtain of air. Air Knives are designed for 24/7 use, have smooth edges and shims for easier cleaning, can be precisely adjusted without tools for faster change-over’s and are custom sized for your application. The Full-Flow feature provides air flow across the entire length. The Full-Flow Air Knife has the compressed air inlet on the rear. It is available in either aluminium or stainless steel construction.

Shim Sets 

A Full-Flow Air Knife has a .002" (.05mm) gap setting. This gap is set with a shim positioned between the cap and the body of the Full-Flow Air Knife. Force and flow through the Full-Flow Air Knife may be easily increased by adding shims to open the gap. Kits include a shim set. Shim sets for aluminum Full-Flow Air Knives include a .001" (0.03mm), .003" (0.08mm) and .004" (0.10mm) thick plastic shim. Shim sets for stainless steel Air Full-Flow Knives include (1) .002" (0.05mm) thick stainless steel shim.

CE Compliant Control Minimizes Compressed Air Use

EXAIR’s digital ETC (Electronic Temperature Control) Cabinet Cooler System keeps electrical enclosures cool while minimizing compressed air use. Independent laboratory tests now certify that the ETC™ is CE compliant to assure safe operation in a wide range of cooling applications, allowing it to work perfectly with our CE compliant Cabinet Cooler units.

The ETC accurately maintains a constant temperature in the electrical enclosure that is slightly under the maximum rating of the electronics. It permits just enough cooling for the electronics without going so cold as to waste compressed air. A digital LED readout displays the temperature of the electrical enclosure (°F or °C), then displays the user temperature setting when pressing the “push to set” button. When that setting is exceeded, the Cabinet Cooler System is activated which circulates 20°F air throughout the electrical enclosure to prevent a high temperature malfunction.

The ETC is suitable for NEMA 4, 4X and 12 environments with a strong polycarbonate plastic housing and sealed membrane push button control. All systems include an automatic drain filter separator to keep moisture in the compressed air out of the electrical enclosure. Models for 120 VAC or 240 VAC are available with cooling capacities up to 2800 Btu/hr. Applications include cooling programmable controllers, CNC panels, computer cabinets, and variable speed drives.

USB Data Logger Available for Digital Flowmeter

EXAIR’s Digital Flowmeter provides an excellent way to monitor compressed air consumption and waste. Now, with the addition of EXAIR’s new USB Data Logger, you can also maintain a history of the Digital Flowmeter’s measurements for analysis.Use the included software to configure the Data Logger to record your flow rate. Record from once a second (about nine hours of data) up to once every 12 hours (over 2 years!).

Regular monitoring of compressed air usage makes it possible for companies to save thousands of dollars per year in compressed air waste by identifying costly leaks or inefficient air products. When the Data Logger is removed from the Digital Flowmeter and plugged into a computer, the data can be viewed in the included software or exported directly into Microsoft Excel®. This allows you to track flow rate easily on your computer.

The Data Logger is available pre-installed on the Digital Flowmeter.Summing Remote Displays, that make it easy to monitor compressed air consumption from a convenient location, are also available.

CE Compliant Air Nozzles Increase Efficiency

EXAIR’s family of Air Nozzles-- from the tiny new Model 1108SS Atto Super Air Nozzle at 2.0 ounces (56.7 grams) of blowing force to the high powerModel 1120 Large Super Air Nozzle at 23 pounds (10.4 kg) of strong blowoff force -- have always provided safe, economical performance. Independent laboratory tests now certify that EXAIR’s entire Air Nozzle family hasalso met the rigorous safety, health, and environmental standards of the European Union in order to attain the CE mark.

By entraining high volumes of room air, EXAIR’s Super Air Nozzles use less compressed air and less energy to provide superior performance to other blowoff products. Unlike open pipe and nozzles that haven’t been optimized, none of EXAIR’s large selection of Super Air Nozzles can be blocked, meeting OSHA’s standard for dead-end pressure 29 CFR 1910.242(b). All of EXAIR’s Super Air Nozzles also fall within OSHA’s noise requirement 29 CFR 1910.95(a).

Cold Gun Increases Tool Life

Cold Gun Increases Tool Life

A Company manufactures intricate machined parts for the automotive, motorcycle and aerospace industries. One of their machinists had a frequent problem rough-milling pocket in type 410 stainless steel when using a two flute 3/8" carbide cutter on their Okuma vertical machining center. Coolant produced thermal shock, resulting in micro cracking of the carbide inserts. Without coolant, thermal cracking of the inserts was almost immediate. They were constantly changing inserts.

The company installed a Model 5215 Cold Gun System. The 20°F cold air kept the inserts cool and allowed all the heat to be carried away on the chips. Tool life increased by 50%.

The Cold Gun incorporates a vortex tube to convert an ordinary supply of compressed air into two low pressure streams, one hot and one cold. The hot airstream is muffled and discharged through the hot air exhaust.  The cold air is muffled and discharged through the flexible hose, which directs it to the point of use.  The magnetic base provides easy mounting and portability. COLD GUN

Heat buildup can ruin expensive tooling as well as the part being machined. In this situation, it would have been easy to constantly ruin a Rs.9000 cutter. When asked how others solve this problem, the machinists replied, "We've seen companies go so far as to defeat the safety interlocks so the machine runs with the doors open - just to blow a little compressed air at the part to cool it. For us, the Cold Gun keeps the tooling cool and allows us to immediately handle the part since the heat blows away with the chips.
