About Air Compressors

Horizontal

Vertical

Compressors turn on when the tank falls to the actuation pressure and they turn off when the tank reaches the maximum pressure.

Gasoline powered compressors cannot be sold to Canada due to import regulations.

High-Flow Low-Pressure Compressed Air Blowers

Also known as regenerative blowers, use these to produce high-flow compressed air with low pressure or vacuum to operate pump drives, lift tables, and conveying systems. Compressed air blowers are also used for drying, exhausting, and aeration.

Air circulates inside the blower housing to compress air, which generates pressure or vacuum. Single-stage blowers circulate air once and then exhaust. Two-stage blowers circulate air twice and then exhaust, creating higher pressure or vacuum than single-stage blowers with the same horsepower.

Inverter-rated blowers have a motor that can run at slow speeds without overheating, so they can be used with a motor speed control (variable frequency drive).

Air Compressors with DC Motor

Compressor

Compressor with Tank

Get compressed air from a DC power source—these compressors can run on a 12-volt vehicle battery (not included) for use on trucks and heavy equipment, or a DC generator. Use them to inflate tires, clean filters, and operate light-duty tools, such as nailers, hammers, and small impact wrenches. For best results with a vehicle battery, use a deep-cycle, large-cell battery rated for continuous use.

Compressors with tank are mounted on a 10-gallon storage tank to handle more demanding applications, such as grinders, saws, and spray guns.

Optional mounting brackets allow you to mount a compressor to a vehicle chassis. Connector assemblies come with a three-foot hose and a connector that can be fixed to a panel or frame for operating compressors installed in difficult-to-reach locations, such as under a vehicle.

Fire Sprinkler Air Compressors

Pressurize air for sprinkler systems. These compressors turn on when the tank falls to the activation pressure and they turn off when the tank reaches the maximum pressure. UL and C-UL listed, as well as CSA and CSA-US certified, they meet U.S. and Canadian safety standards.
