sandblasting machine use 424cfm Screw air compressor
Double screw
Extremely high operating reliability and efficiency, twin-screw air compressor host structure is simple, almost no wearing parts, so long service life
Easy to operate and maintain
Excellent dynamic balance characteristics.The double screw structure is very stable under the operating condition
Small size, light weight, easy to use
High efficiency.Because the screw has the characteristic of forced gas transmission, the volume flow is almost not affected by the exhaust pressure
Low noise, low vibration
High quality compressed air





High efficiency screw main machine (silent type)
Conventional screw air compressor using a new asymmetric line 5:6 screw host, from the current sealing to the sealing technology upgrade, triple seal to ensure that the host oil leakage, and by increasing the size of the rotor, optimize the internal structure of the rotor, gas production efficiency increased by 5% to 10%, to ensure the efficiency of the unit.
The motor
Energy-saving motor completely enclosed outside fan motor, insulation grade F, protection grade IP54, effectively prevent dust, water stains into the motor.At the same time, the standard configuration of the motor phase sequence protection function and thermocouple, by testing the motor coil temperature, protect the motor and compressor set, long-term continuous barrier-free operation.
Energy saving intake valve
The air inlet valve can effectively control the loading and unloading of the unit. It adopts lifting structure, has no gap, and can be sealed without cylinder pneumatic control and sealing diaphragm, saving energy.
cooler
Adopt large area design, improve cooling efficiency, effectively prevent the machine from high temperature, the inner wall do anti-corrosion treatment, adapt to more severe working conditions, extend the service life
Air filter system
Specially designed for dust environment, the 2-stage separation mode of large air filter, centrifugal and filtration separation is adopted to reduce pressure loss and energy consumption, and the unit can operate normally and stably under complex working conditions
The oil filter
Adopt large oil filter, high separation efficiency, ensure the cleanness of oil, prolong the service life of lubricating oil and all parts inside the unit
Oil and gas separator
Oil and gas separator, through centrifugal separation, gravity separation, filtration separation three stages of oil treatment, make the residual oil in the exhaust control under 3ppm.
