5.5 kW 7.5 Compresseur d'air rotatif industriel à vis HP, prix bon marché

Premièrement, the motor of our PM VSD industrial air compressor is “IE4”. The electrical conversion efficiency is as high as 95%. Cependant, many air compressor products on the market are not like this. The motor efficiency level of some air compressors is “IE3”. There’s even an “IE2” performance class.

Deuxièmement, our airend uses six heavy-duty bearings. Outre, it uses a Morse taper connection. The vibration rate is within 1mm per second. So it works better.

Troisièmement, we use a unique inverter. The volume is larger than the 2nd generation product. Therefore our 7.5 hp rotary screw air compressor is more stable.

En outre, our oil-air separator tank adopts a 5-stage separation technology. Export oil content is less than or equal to 2 ppm. It is better than other screw air compressors.

The cooler is 2 times larger than the 2nd generation product. The heat dissipation effect is better. Outre, the fan is 4 times larger than the 2nd generation product. It has stronger suction. So the cooling effect is more optimized.

With a fully enclosed casing, the decibel is less than 65 décibels. There is a filter sponge on the outer edge of the case. It not only has the effect of filtering wind and sand but also has a certain noise-reduction effect.

1. Replace the oil and oil filter;
2. Clean the air filter;
3. Check whether the air compressor is leaking or loose;
4. And check the sewage discharge of the oil storage tank;
5. Check the motor temperature rise, actuel, and the sound of the airend.

1. Not replace the air compressor lubricant oil and oil filter;
2. Check oil-air separator differential pressure;
3. Clean the air compressor cooler;
4. Manual inspection of the safety valve;
5. Others same as above.

1. Replace oil and oil filter for the 7.5 compresseur d'air rotatif à vis HP;
2. Change the oil-air separation core (or the pressure difference exceeds 0.08MPa);
3. Replace lubricating oil for motor and cooling fan bearings;
4. Electrical insulation and contact inspection;
5. Safety protection device inspection;
6. Others same as above.

1. Replace the oil and oil filter of the industrial air compressor;
2. Control system aging inspection,
3. Take the safety valve and pressure gauge to the specified department for calibration or replacement,
4. Check or replace the pressure controller, solenoid valve, soupape de pression minimale, temperature controller, intake valve, transmission device,
5. Inspection of the electrical master switch;
6. Others same as above.
