For compressor units with intake pressure, the BK 23 to BK 52 block series feature a pressure-tight crankcase for uniform absorption of the internal gas forces.

The high process reliability assured by manufacture in-house at BAUER KOMPRESSOREN provides the basis for narrow tolerances, minimum dead space and high energy efficiency.

Combined with the proven plasma-nitrided cylinders and honed cylinder surface, piston rings featuring a special chrome-plated finish ensure low friction, optimum lubrication and long service life.

The oil pan flange-mounted underneath the crankcase reduces oil consumption and allows for installation angles of up to 30° in all directions.

The use of single-acting plungers reduces blowby losses and increases efficiency.
