Air system overview
Maintainer Corp. of Iowa installs air systems per the customer’s requirements. They
range from small gas powered air compressors to large hydraulic driven rotary screw air
compressors.
Maintainer Corp. of Iowa designs and installs most hydraulic systems that run the air
compressors. The systems are designed using the air compressor manufacturer’s
specifications for each unit. Horsepower requirements, R.P.M. and duty cycle are the
determining factors when designing the systems.
The air system components are matched to the air compressor output. The air hose size,
air storage capacity, Filter – Lubricator – Regulator and hose reel are matched to the air
compressor output.
The hydraulic system used on the air compressor may be an open or closed center
hydraulic system. A solenoid valve and oil flow control valve control the hydraulic flow
to the hydraulic motor. An electric pressure switch controls the solenoid valve. The
pressure switch will energize the solenoid valve when the air system lowers to a set
pressure. This pressure is approximately 120 P.S.I. The pressure switch will de-energize
the solenoid valve when the air system reaches a higher set pressure. This pressure is
approximately 150 P.S.I.
The air reservoir tank is equipped with a 165 P.S.I. pop off valve to prevent the tank from
over pressurizing. There is a drain in the tank. The tank should be drained at the end of
each shift. The air is directed out of the air tank to air system components.
