Mobile Compressors FK & Al HG compressors.

Bock vehicle compressors of FK range are the result of many years of experience in the domain of mobile cooling systems. The unsurpassed light, compact, robust design and wide r.p.m. range are only some of the outstanding feature of this unique product range of 2, 4, 6 cylinder compressors.

The K version is a special innovation with a unique valve plate system for most stringent requirements in bus and coach air-conditioning systems.

Capacity ranges from 10.3 to 84.9 m3/h (at 1450rpm) with 4 base models and 14 capacity stages.

Bock aluminium HG compressors, designed to be lightweight are around 40% lighter than standard compressors and offer system manufacturers new possibilities on bus air-conditioning and truck refrigeration design.

Capacity for these aluminium semi-hermetic compressor ranges from 44.3 to 66.1 m3/h (2,900 rpm)
