Compressor Parts

Whether it’s a brand name or a private label, Hope Air Systems has the right replacement part for your equipment. We will recommend the part that meets your performance and budget requirements. Hope Air Systems has a 60,000 square foot warehouse facility in Central Massachusetts and satellite stocking locations in Rhode Island, New Hampshire and Maine. It can meet your immediate requirement for parts including:

Premium Fluids

Kaeser Premium Fluids are specially formulated and offer outstanding wear protection, long life and smooth lubrication—even at low temperatures. They also separate easily from water to simplify condensate treatment.

Air filter elements

Replacement air filter elements prevent dirt and dust entering and damaging the airend. When changed at regular intervals, they substantially extend the compressor's service life.

Separator cartridge kit

Kaeser offers a separator cartridge kit containing the appropriate cartridge and gaskets for each compressor model. Separator cartridges with deep bed filtration for models AS to ES have an operational life of up to 8000 hours.

Fluid filter

Kaeser's durable fluid filters are designed for low pressure drop and longer service intervals. By effectively cleaning the recirculating fluid, they protect and preserve the airend, reduce premature wear and extend the compressor's overall service life.

Service and repair kits

Kaeser service and repair kits contain parts that wear over time. Having these kits in stock and readily available, makes routine maintenance easier and helps streamline scheduled downtime.

Filter elements

Genuine Kaeser replacement filter elements guarantee effective filtration and low pressure drop. They seal perfectly with the filter housing, are supported by stainless steel orifice tubes and fitted with oil and acid resistant end caps.

Activated carbon filters

Designed for use in Kaeser Condensate Filters, activated carbon filter elements are easy to replace. Plus, they help reduce costs associated with contaminated condensate disposal.


Kaeser replacement V-belts are specially designed and selected to meet demanding compressor drive requirements. In conjunction with Kaeser's automatic belt tensioning system, these belts offer the ultimate in durability and performance.

Maintenance kits

Kaeser maintenance kits contain exactly the right parts for preventive maintenance. Categorized by service hours to make ordering simple, these maintenance kits are stocked with Kaeser Genuine Parts to keep your system running at optimum performance.
