What is the difference between the Line Vac, the Light Duty Line Vac and the Heavy Duty Line Vac?

EXAIR has an expansive line of air conveying products. 

  • The Light Duty Line Vac performs best for short runs and small transfer rates
  • The Line Vac is designed for longer runs and greater transfer rates than the Light Duty Line Vacs
  • The Heavy Duty Line Vac is our most powerful and durable conveyor and is made of hardened alloy to resist abrasion. This construction allows the Heavy Duty Line Vac to convey more material in less time while helping to prevent premature wear.

Call an Application Engineer for help in selecting the correct model for your application.

What is the difference between the Model 3825 and Model 3925 Adjustable Spot Cooler Systems?

Model 3825 and 3925 utilize the same cold air producing Vortex Tube. The only difference is the hose kit that is included with each model. Model 3825 is shipped with a single-point hose kit. Model 3925 is shipped with a dual-point hose kit to provide chilled air to two points instead of one.

What is the difference between the Soft Grip Safety Air Gun and the Heavy Duty Safety Air Gun?

The Soft Grip Safety Air Gun has a 1/4 NPT female compressed air connection, is physically smaller and can be outfitted with 1/8, 1/4, 3/8 and 1/2 NPT nozzles. The Heavy Duty Safety Air Gun has a 3/8 NPT female compressed air connection, is larger and can be outfitted with 1/4, 3/8 and 1/2 NPT nozzles.

What is the difference between the Super Air Amplifier and the Adjustable Air Amplifier?

The Super Air Amplifier is only available in Aluminum whereas the Adjustable Air Amplifier is available in aluminum and stainless steel.  Also, all sizes of the Super Air Amplifier have a 2 bolt flange (except the 8" (203mm) Super Air Amplifier) molded into its body for mounting.  The Adjustable Air Amplifier must be mounted externally or with hard piping. The key operating difference is that a Super Air Amplifier operates with a patented shim to set the air gap which allows it to consume 40% less air than an Adjustable Air Amplifier. This patented shim also allows for a higher amplification ratio than the Adjustable Air Amplifer models. The Super Air Amplifier Shims can be used on an Adjustable Air Amplifier if you wish to decrease the air consumption and have a set air gap.

What is the difference between the Vortex Tube and other cold air products like the Cold Gun?

The Vortex Tube is the fundamental component inside all the applied EXAIR products that generate cold airflow. The Vortex Tube is available in 3 different sizes and produces a wide span of cooling capacities. All models shown in the catalog have an adjustable valve at the hot end that can change the proportions of hot and cold airflow to their respective ends. On special order, this valve can be replaced with a preset orifice that will provide a pre-determined amount of temperature drop/rise. The Vortex Tube also contains a series of inserts called “generators” that offer a wide range of flow rates for each Vortex Tube size. These generators size the flow to the application.

Most of the applied products (Cabinet Cooler, Cold Gun, Mini Cooler and Component Cooler) have a fixed total flow capacity that is ideal for that product. The valve has been replaced with a preset orifice that allows the Vortex Tube to deliver the highest cooling capacity available. The exception is the Adjustable Spot Cooler, where the temperature is adjustable and flow rates can be changed by using the interchangeable generators. All of these cold air products include other features that make them easy to mount and keep the noise level low.

What is the material of construction of the Chip Shield?

The Chip Shield is made of durable polycarbonate.

What is the material of EXAIR Cabinet Coolers?

NEMA 12 are stainless steel internally and aluminum externally. NEMA 4 are aluminum. NEMA 4X are 303 stainless steel and also stocked made from 316 stainless steel.

What is the material of the Super Air Nozzle?

The Model 1100, 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1112, 1113, 1114, 1115, 1116, 1117, 1118, 1119, 1120, 1121, 1122 and HP1125 Super Air Nozzles are made from a Zinc-Aluminum alloy, while the 1100SS, 1101SS, 1102SS, 1103SS, 1104SS, 1105SS, 1106SS, 1107SS, 1108SS, 1109SS, 1110SS, 1112SS, 1113SS, 1122SS and HP1125SS are made from Type 316 Stainless Steel. The Model 1100-PEEK, 1102-PEEK and 1110-PEEK Super Air Nozzle are made of plastic.

What is the maximum draw height a Siphon Fed Nozzle can draw from?

The Siphon Fed Atomizing Nozzles can draw up to a 36" height. If drawing from a container, this means you would want the bottom of the container to be no lower than 36" below the liquid inlet to the atomizing nozzle.
