PURPOSE AND SHORT DESCRIPTION
The 1-stage oil-less compressor model OL 512, and OL 812, as well as the 2-stage oil-less compressor model
OL 524, are used to compress air in the pressure ranges up to 110 psi (1-stage compressor models) to 220 psi
(2-stage compressor models)
All compressors operate with three cylinders and are air-cooled (Fig. 1 to Fig. 4). The cylinders are set in
Y- configuration, allowing for a small compact design.
A special feature of these models are that they operate without any oil in the crankcase. This is the result of the
following construction characteristics:
- friction treated surface of the cylinders
- PTFE (polytetrafluoride ethylene) compound coated piston guiding surfaces
- piston rings made exclusively from special PTFE compound.
These compressor models need very little maintenance because of their oil-less operation, therefore an oil
change or a special condensate disposal is not necessary.
The outstanding characteristic of this compressor model is their long life which is the result of
- low friction and low wear of cylinders and pistons
- the corrosion resistant material used for all parts coming into contact with the air stream
- optimal cooling of all moving parts (air intake through crankcase).
The oil-less compressor standard equipment:
- After-cooler for each cylinder and each manifold
- Air filter maintenance indicator
