Compressors equipped with Longbore™ pistons have improved efficiencies, are more reliable, produces less moisture buildup, have a smaller footprint with less required maintenance.

Longbore™ piston and cylinders move up to 6 times more volume than standard compressors, so they compress more air on each stroke. The Result is increased compressor efficiency, faster recovery, and lower RPM for reduced noise.


Driving Longbore™ pistons require fast, powerful, & robust linear motion. The drive that does this best is RISE patented Beltscrew™. Compared to standard drives, Beltscrew™ is the best of both belts and screws: 

     BeltScrew™ has the speed of a belt and the strength of a screw.
