Cross-type
Many spare parts for breathing air compressors are specifically designed for use with a particular compressor type or series. However, a large number of accessories and retrofit kits for breathing air and high-pressure compressors are type-independent and manufacturer-independent.
These include, among others, refill kits, filter housings, hoses, as well as pressure gauges and pressure switches. Such components are often manufacturer-neutral spare and accessory parts, enabling flexible maintenance and retrofitting across a wide range of compressor types and brands.
