9 Provides the mechanical drive to produce air. This system is composed of chassis, airend unit,
pulleys and belts.
9
As a motor thee phase squirrel caged asynchronous motor is used.
9 The pulleys are standard designed and produced from taper lock hub bed GG22 material for easy
mounting and sensitively balanced.
9 The belts are V type, standard and antistatic, heat resistant and long life.
9
With our special design, the pulley adjustment has been simplified and belt life has been
extended.
Under the group of “Drive system” installation pictures and parts lists are included in the
enclosed number 3 booklet.

INTAKE CONTROL SYSTEM
9
It provides the operation of your compressor at adjusted pressure interval by eliminating the
hazardous dusts that the compressor may absorb from external environment.
Intake System
9 The dusts inside the air absorbed by your compressor enter everywhere that oil penetrate with
their corrosive effects and corrodes them. The life of bearings, o-rings and the seals are rapidly
decreased due to increased friction. In addition with the corrosive effect of dust, the blocked filters
absorb less air and the capacity of the compressor drops, operating temperature rises and this
adversely affects negatively the internal accessories of compressor and the hoses rapidly
hardened, bearings are corroded, oil is more rapidly contaminated as cooling air and suction air is
limited. Shortly, the cleaning and maintenance activities not performed on time causes energy loss
(financial loss) instead of saving.
9 Suction system is composed of panel filter outside of your compressor, the intake filter inside your
compressor and connection hose.

9 The intake control system is composed of; intake valve, solenoid valves, control air line hoses and
safety pressure switch. In the systems with electronic controller unit or inverter, pressure sensors
are used for obtaining pressure data.
9 The aim of intake control system is to operate the compressor in most economic way
9 During the start up of compressor, the intake system stays closed and prevents unnecessary
loading and establish an impact free start up.
9 When the demanded pressure value is reached, it closes the suction again and enables the
rotation of compressor motor by wasting minimum power. Instead of rapid start up and stopping,
only the air suction of the compressor is blocked and economic operation is supplied
9 According the pressure on the utility line, the electronic controller unit or pressure switch
commands to intake valve. The intake valve closes and opens the compressor’s air suction this
way.
9 When the compressor is stopped the pressure in the oil tank moves in the opposite direction tries
to turn the airend in opposite direction. The intake valve at this moment operates as a check valve
and closes suction and prevents the backward rotation of airend and splashing of the oil
backwards.
