COMPAIR HOLMAN Other models

The register lists here 11 versions with unladen weights from 848 to 2,115 kg, gross weights from 900 to 2,350 kg and widths from 1,280 to 1,870 mm.

Towable compressors of this kind supply building sites without a fixed power connection with compressed air for breakers, sandblasting equipment or nail guns, and were sold to construction firms and plant-hire companies over decades. Unlike plain load trailers, they carry a substantial part of their gross weight permanently in the body, in the compressor unit, engine and cooler, rather than in a variable load.

On a used example, besides the usual chassis check – rust on the frame, the condition of the overrun coupling, brake and wheel bearings – the technical condition of the compressor unit counts above all: operating hours, the condition of the engine, oil separator and cooler, and the tightness of the compressed-air lines and valves. Parts for the chassis are usually available independently of the maker, while the compressor unit itself calls for specialist knowledge of industrial compressors.
