Why Choose Lingyu 350 cfm Screw Air Compressor
(1) Stable Compressor Quality
The airend of the screw compressor is Hanbell brand. It uses good materials. The rotor bearing is the SKF brand in Sweden. It has a long service life — up to 100,000 hours. The compressor airend is compact in size and low in speed. Volumetric efficiency is high. In addition, the protection level of the air compressor motor is IP54. The insulation class is F class. So waterproof and dust-proof performance is good. Besides, the motor uses high-grade electromagnetic steel. It can withstand the temperature of 180°C. Therefore, our rotary screw air compressor has a low failure rate.
(2) Intelligent Air Compressor Control System
This 350 cfm air compressor adopts microcomputer control. Real-time online monitoring: pressure, power, and temperature fluctuations. The operating status & data and fault warning are clear at a glance. Moreover, it can prompt the life of compressor-wearing parts. So maintenance is easy.
(3) Structure And Transmission Advantages
Due to the enlarged oil-air system, the pressure loss of the air compressor pipeline is small. This 350 cfm compressor adopts an elastic coupling direct drive. Avoid the disadvantages of belt drive. That is, it is easy to generate slip, and the transmission efficiency is low. The efficiency of the belt drive air compressor is only about 85%. Moreover, the elastic coupling can eliminate the misalignment to reduce the starting shock load. Finally, extend the service life of airend and bearings.
(4) Advantages of Oil-air Separation System
This 350 cfm air compressor has a good oil-air separation effect. The oil content of the outlet air is lower than 3PPM. Moreover, our oil separator element has a long service life. It’s up to 8000 hours. The characteristic is three-stage separation. That is vortex centrifugation, gravity, and filtration separation.
FAQs
Q1: Can I directly add an inverter to the fixed-speed air compressor by myself?
A1: No. It can’t achieve the expected effect after installing the frequency converter.
Q2: How much power motor does a 10m³/min air compressor need?
A2: For our screw air compressor, you can choose the 75 hp air compressor. When the air pressure is 7 bar, the air capacity can reach 10m³/min.
Q3: What kind of lubricant oil do you use for your 350 cfm screw air compressor?
A3: Our 75hp air compressor uses the Shell brand S46 lubricant oil.
Q4: What do I do if forget the air compressor password?
A4: This is not a big problem. Please contact us for the password.
Q5: Do I also need the compressed air dryer for the 75 hp screw compressor?
A5: This is mainly based on your industry application. If your industry has a requirement for water content, the compressor air dryer is necessary. Of course, most industries generally require at least a refrigerant air dryer.
Q6: What’s the production time for your 350 cfm air compressor?
Q7: If you only need the regular 350 cfm compressor, the delivery time is about 20 days.
