Oil Free Rotary Screw Air Compressor 145 Psi Essay For Installation
Oil Free Rotary Screw Air Compressor Introduction
A rotary screw compressor is a type of gas compressor which uses a
rotary type positive displacement mechanism. They are commonly used
to replace piston compressors where large volumes of high pressure
air are needed, either for large industrial applications or to
operate high-power air tools such as jackhammers.
The gas compression process of a rotary screw is a continuous
sweeping motion, so there is very little pulsation or surging of
flow, as occurs with piston compressors.
Oil Free Rotary Screw Air Compressor Features
SEPARATED COOLING SYSTEM
The centrifugal fan is activated automatically by the thermostatic
control through the controller. This allows the machine to quickly
reach
and precisely maintain the ideal operating temperature.
THERMOSTATIC VALVE
The thermostatic valve regulates the oil temperature, preventing
the formation
of condensate inside the oil-separator vessel.
EASE Of ACCESS TO ALL COMPONENTS
All main components can be readily accessed from the large front
access door. This allows convenient inspection with fast
and simple maintenance.
COMPACT, SPACE SAVING DESIGN
The compact design is ideal for installation when space is
restricted or in situations when the compressor needs to be
installed near the production activity.
BELT-DRIVEN TRANSMISSION
The POLY-V belt-drive ensures significantly lower power losses and
three times the service life compared to standard range “V” type
belts fitted to other compressors on the market.
Belt tensioning is carried out through a slider system.
LOW NOISE LEVEL
The centrifugal fan design along with the careful arrangement of
all other components within the machine added to extensive sound
insulation results in the LGSD, offering very low operating noise
levels.
