5 - 25 Horsepower Piston Air Compressors

What is a piston air compressor?

A piston air compressor is the oldest compressed air technology and can be found in auto shops, construction sites, homes, medical offices, farms and many other processes and applications. Piston technology uses positive displacement to produce compressed air through a system of valves and pistons, much like a car. Cylinders pull air in through a valve disc that opens downward and then closes as the piston moves upward. The compressed air is then passed to an aftercooler, tank, water separator, coalescing filters, and dryer. Dryers and filters remove most of the oil, water, and other contaminants from the air, usually down to 2-5 ppm.

Why purchase a piston air compressor?

1) Piston air compressors are lower in initial cost but cost more over time than screw technology.
2) Piston air compressors are great for applications that require low duty cycle and running hours.
3) Piston air compressors (Emax) are now quiet as screw technology and offer comparable energy savings with variable speed.
4) Piston air compressor technology is well understood due to it's simplicity and age, therefore parts and technicians are usually readily available for service.
5) Piston air compressors can be moved relatively easily to the application.
6) Piston air compressors offer higher pressures and voltages.
7) Piston air compressors will give you years of service with proper maintenance.
