3-30 HP Rotary V-Belt Drive

Challenge: How to construct a modest horsepower air compressor that is economical, efficient and reliable, yet has flexibility to increase working pressure at a future date.

Myth: So-called "belt" drive systems are difficult to adjust, either being too loose or too tight, contributing to operating inefficiency and even early failure.

Learn from us: Kaeser's rotary screw compressors with V-Belt design are the most economical and reliable in the industry. Thanks to its highly effective belt-tensioning system, which ensures excellent transmission efficiency and reduced maintenance costs, any drawbacks to a belt system have been eliminated. What's more, the V-Belt design is very flexible and can be easily modified, in the field, if a change in working pressure becomes necessary.

Hope Air Systems responds: The Kaeser SX, SM, SK and AS Series offer many innovations and features normally associated with larger compressor systems:

Sigma Control System

A simple and reliable interface offers convenient pressure control and system monitoring with status displays and service indicators. Displays include discharge pressure and temperature, load and service hours as well as fault indicators.

Sigma Profile Airend

Our power-saving, proprietary airend design delivers pressures up to 217 psig. Kaeser uses a newly designed airend for this AS series. It is precision-machined to close tolerances and optimized in size and profile to match the low airend speeds with their best specific performance, up to 20 percent less energy than comparable airends.

Belt Drive with Automatic Tensioning

A new ribbed single belt drive efficiently transfers power from motor to airend. The Kaeser automatic tensioning device maintains proper tension to maximize energy efficiency, prolong belt life and simplify routine maintenance.

Efficient Separator System

Most of the cooling fluid is separated from the air by centrifugal action in the separator tank. Any remaining fluid is separated by a two-stage separator cartridge. This triple action doubles the cartridge service life and reduces fluid carryover to two ppm or less.

Cooling Air Filter Mats

Ambient air used for cooling is usually contaminated with dust and particulates. Filter mats, through which cooling air id drawn into the cabinet, prevent premature clogging of the cooler and inlet filter.
