Model SGP220A: specification 37k/50, exhaust 0.8m, noise 75, shape1900 *1300 *1200, diameter 3/4*pt*2 ball valve, weight 1250kg. Accessories have powerful water purification and oil separation functions, and adopt all-copper motor, which is fast in air supply, durable and not easy to deform, and can run smoothly at high speed.
Model TG90A-680: specification 37k/50, displacement 300L, noise 75, shape 120*4 1*75CM, diameter 5/6*pt*2 ball valve, weight 70kg. It is composed of excellent radiating fins and steel pipes, and the heat dissipation effect is remarkable. The parts of connecting rod are accurately priced, using standard balance.
Model 0.25/ 12.5 single item: specification 25k/45, exhaust 0.25m, noise 80, shape 106*44*78, diameter 3/4*pt*2 ball valve, weight 65kg. The use of air filter can reduce flow resistance, reduce inhalation and noise, filter dust, and greatly improve the service life of equipment.
Noise control of air compressor
Install muffler: The main noise sources are air inlet and air outlet, and appropriate air inlet and exhaust muffler should be selected. The intake noise spectrum of air compressor presents low frequency characteristics, and the intake muffler should adopt resistance structure or impedance composite structure with individual resistance as the main factor. The air compressor has high exhaust pressure and fast airflow speed, so a small hole muffler should be used at the outlet of the air compressor.
Set up anechoic tunnel: underground or semi-underground tunnel, and the anechoic tunnel wall is made of sound-absorbing bricks. Connect the air inlet pipe of the air compressor with the silencing tunnel, so that air can enter the air compressor through the silencing tunnel. The use of muffler tunnel can greatly reduce the intake noise of air compressor and prolong the service life of muffler.
Establish sound insulation cover: After installing muffler or muffler tunnel at the inlet and outlet of air compressor, the airflow noise can be reduced to below 80db, but the mechanical noise and motor noise of air compressor are still high, so sound insulation cover should be installed on air compressor unit.
