How the compressor works
Page 18
BOGE Operating instructions for scroll compressors, series EO 6...EO 22 D
1 Drive pulley
Power transmission from the electric motor to the compressor in the cor-
responding design using V-belt.
2 Drive motor
The electric motor drives the compressor with the corresponding trans-
mission ratios and V-belt.
3 Suction filter
The suction filter cleans the air drawn in from the compressor stage.
4 Safety valve
The safety valve limits the maximum pressure in the system to a defined
limit value. It blows off if the final pressure is exceeded due to a fault.
5 Temperature sensor
This sensor monitors the temperature of the compressed air.
6 Non-return valve
The non-return valve is located before the primary cooler and prevents
compressed air from flowing back into the compressor from the com-
pressed air network.

Cooling air requirement
Please refer to the following table for the cooling air requirement and the size
of the supply air inlets for your compressor. Ensure that flaps and weather pro-
tection grids have the necessary free cross section. We generally recommend
that you contact a specialist company to carry out the duct design and con-
struction work.
