Reciprocating Compressors
Reciprocating Air Compressors
Reciprocating air compressors, also known as piston compressors, are the economical compressor system option ideally suited for intermittent duty cycles. Our durable designs are adaptable for many applications and range from inexpensive .75HP to more rugged industrial models up to 125HP. We carry oil-lubricated, oil-free, and gas driven reciprocating compressor models.
OL Series 5-15HP
OL Series is the ideal reciprocating oil-less air compressor

Rotary – Piston
THE BEST OF BOTH WORLDS + THE SECURITY OF A BACKUP
These “hybrid” compressors offer the durability and 100% duty cycle of a rotary screw, together with the intermittent demand and energy savings of a piston. Under normal operation, the rotary runs continuously, as they are designed to, and the piston automatically runs intermittently when the rotary cannot keep up. If no air is required for 10 minutes, the rotary will also turn off and remain in standby mode until air is required again, providing a seamless supply of air while conserving electricity.
- During periods when air demand is light, you can operate the piston only, again conserving electricity, all with the added peace of mind of having two separate units that can be operated individually ensuring you will never be without air.
- Up to 45 total horse-power available, delivering 180 CFM @ 100 PSI, maximum pressure up to 175 PSI.
- Sizing guide: Determine the CFM required under normal operation and size the rotary to supply this CFM. Then determine the peak CFM required and size the piston to supply this additional CFM.
- Pricing: Add together the cost of the two units with 80-gallon horizontal tanks for a 120-gallon horizontal system or add together the cost of the two units with 120-gallon vertical tanks for a 240-gallon horizontal system.
