They are available in many cooling capacities for large and small control panels. It can accurately maintain a constant temperature that is slightly under the maximum rating of the electronics, permitting just enough cooling for the electronics without going so cold as to waste compressed air.
The control activates the solenoid valve included when the temperature setting is exceeded. Cabinet Cooler not included. Kits including a solenoid valve and thermostat are available to retrofit existing Cabinet Coolers which are operating continuously. Using a thermostat and solenoid on your Cabinet Cooler is the most efficient, and recommended, way to operate a Cabinet Cooler. The thermostat and solenoid valve will turn the Cabinet Cooler on and off as needed to maintain a cool internal environment for your cabinet.
A new solution to an old problem. Heat build up on dry machining operations reduces tool life and machining rates. Operation is quiet and there are no moving parts to wear out. It will remove heat to prolong tool life and increase productivity on machining operations when liquid coolants cannot be used. The Cold Gun is also an alternative to expensive mist systems.
It eliminates the costs associated with the purchase and disposal of cutting fluids and worker related health problems from breathing airborne coolants or slipping on wet floors. Integrated fuse protects against voltage spikes, modular cable eases routing, electromagnetic shielding protects other sensitive electronics. Choose 2 outlet or 4 outlet model. Two other variations for VAC are also available. These single stage, cylindrical units are compact and easy to mount at the point of use.
They can be held in place by threading them directly onto a compressed air line or with the use of a mounting clip. EXAIR offers a variety of mufflers, tubing, check valves, and fittings that make it easy to build a vacuum system best suited to your vacuum application. A low cost, reliable, maintenance free solution to a variety of industrial spot cooling problems. Using an ordinary supply of compressed air as a power source, vortex tubes create two streams of air, one hot and one cold, with no moving parts.
The wear resistance of stainless steel, as well as its resistance to corrosion and oxidation, assures that EXAIR Vortex Tubes will provide years of reliable, maintenance-free operation. Vortex Tubes can produce:. Temperatures, flows and cooling power are adjustable over a wide range using the control valve on the hot end exhaust.
With the turn of a knob, you can select the temperature best suited to your application. A swivel magnetic base provides easy mounting and portability. Flexible tubing that holds its position directs the cold air. A proven way to reduce downtime and increase productivity on a variety of operations involving small parts where heat is a problem.
The Mini Cooler is particularly effective on high speed operations to prevent burning, melting and heat related breakage. Operation is quiet 76 dBA and there are no moving parts to wear out. An internal float automatically activates the drain when full. EXAIR's Pressure Regulators permit easy selection of an operating pressure that will allow the air product to work properly without using excessive amounts of compressed air. Many sizes are available and a pressure gauge is included.
Mounting brackets are used to mount Filters and Pressure Regulators to a frame, wall or sturdy surface. Coupling brackets are used to couple the filter and regulator together to create a rigid, sealed assembly. Simply mount the hose in close proximity to the application and bend it.
Type and Stainless Steel. Magnetic bases are suited to applications where frequent movement of the air product is required. The powerful magnet permits horizontal or vertical mounting. A valve is provided that can be used to vary the force and flow. Hose lengths are 10', 20', 30', 40' and 50'. In stock for all hose compatible Line Vacs up to 3". This transparent conveying hose is a spiral reinforced PVC material used for a variety of material transfer applications.
EXAIR Silencing Mufflers help to reduce work area noise produced by air exhausting from cylinders, valves and other air powered equipment. They also eliminate harmful dead end pressures. Each style of Silencing Muffler shown has a high airflow capacity, with low back pressure.
Popular NPT sizes are ideal for new and existing installations. Drum Dollys are available for 5, 30, 55 and gallon drums. If your application may require moving your vacuum around the plant, these dollys are rugged and will make moving the vacuum systems from place to place easy.
Some applications require an intermittent demand for a high volume of compressed air. This can cause fluctuations in pressure and volume throughout the compressed air system with some points being "starved" for compressed air.
EXAIR's Model 60 Gallon Receiver Tank can be installed near the point of high demand so there is an additional supply of compressed air available for a short duration. The time between the high volume demand occurrences should be long enough so the compressor has enough time to replenish the Receiver Tank. Pressure and Vacuum gauges provide accurate reading of pressure for all of your compressed air products and applications.

Email to a Friend. Sign up for promotion alerts. Compressed air, normally PSIG 5. At up to 1,, RPM, this air stream revolves toward the hot end where some escapes through the control valve. The remaining air, still spinning, is forced back through the center of this outer vortex. The inner stream gives off kinetic energy in the form of heat to the outer stream and exits the vortex tube as cold air.
The outer stream exits the opposite end as hot air. The Vortex Tube Performance Charts below give approximate temperature drops and rises from inlet air temperature produced by a vortex tube set at each cold fraction.
Back Pressure: The performance of a vortex tube deteriorates with back pressure on the cold air exhaust. Low back pressure, up to 2 PSIG. Filtration: The use of clean air is essential, and filtration of 25 microns or less is recommended.
EXAIR filters contain a five micron element and are properly sized for flow. Inlet Air Temperature: A vortex tube provides a temperature drop from supply air temperature see Performance Charts above.
Elevated inlet temperatures will produce a corresponding rise in cold air temperatures. Normally, muffling is not required if the cold air is ducted. Maximum pressure rating is PSIG

Vortex Tubes and Spot Cooling Products
There are many theories regarding the dynamics of a vortex tube and how it works. Many a graduate student has studied them as part of their research requirements. He was performing experiments on on a vortex-type pump that he had developed and noticed that warm air exhausted from one end and cold air from the other! Ranque quickly stopped work on the pump, and started a company to take advantage of the commercial possibilities for this odd little device that produced both hot and cold air, using only compressed air, with no moving parts. The company was not successful, and the vortex tube was forgotten until when Rudolph Hilsch, a German physicist, published a widely read paper on the device.
