Compressed air connection for KOMPBERG BKB22 TWIN
3.4. Compressed air treatment
Depending on the desired quality of compressed air, additional equipment for air
purification such as dehydrators, filters or drier should be installed downstream the
compressor.
Our specialists will select appropriate equipment free of charge.
4. Technical description
4.1. Applications
The KOMPBERG series booster compressors are intended for boosting air pressure from
1.0-1.3 MPa (KOMPBERG BKB22 TWIN) on the suction side, to 2.5-4.0 MPa on the
pressure side. The booster is provided with an oil filter and end cooler.
4.2. Main components
The booster compressor comprises an oil piston compressor with “V” cylinder
arrangement at 90° angle. The compressor is driven by an electric motor with a belt
transmission. A common frame supports the compressor, motor and air end cooler with
fans and filters.
4.3. The compressor
It is a single-stage compressor with two cylinders, one-side action, with “V” cylinder
arrangement at 90° angle.
The compressor has a tunelled iron cast crankcase. The crankcase bottom serves also
as an oil sump with the oil suction filter built in. The oil filter is installed in the oil pump.
Two cylinders with valves are mounted to the crankcase. The valves are held in place in
their seats in the head with adjustment bolts through special thrust sleeves. The cylinders
have special ribs to ensure efficient heat removal.
The crankshaft forged of increased impact-resistant steel is supported on two rolling
bearings. On one side, the crankshaft is provided with a cone end for pulley mounting,
whereas the other end drives the oil gear pump.
On a skin-hardened crank pin of the shaft, two connecting rods with thin-wall double-split
bearing bushings are mounted.
There are no separate heads in the compressor, as the cylinder and head is a one-
component iron cast. Both cylinders are linked with a common suction collector, at the
inlet side, and with the air end cooler, at the outlet side.
