Dry Oil-free Series

Factory direct efficient SWT-55A/W Dry Oil-free Series air compressor


Dry oil-free air compressor

Features and Advantages

1,Driven by permanent magnet variable frequency motor

■ SWTV oil-free air compressor, with matching variable speed inverter and hybrid permanent magnet (HPM®) motor, provides unparalleled energy e ciency at all speeds, and has excellent reliability.

■ They provide ISO 8573-1:2010 grade 0 certi ed 100% oil-free air for most critical applications.

■ There will be no wear, leakage or motor bearings, guide wheels, belts, couplings or motor shaft seals that need to be replaced.

■ SEIZE will reduce operating costs through its dynamic e ciency-a truly remarkable technology.

2,The intercooler is equipped with a gas-water separator to protect the rotor coating of the high-pressure section from damage

The CYCLONE type large-capacity gas-water separator is used to remove the condensed water in the compressed air, protect the second-stage rotor, extend the life of the main engine, and provide a suitable working environment for the compressor.

3,The pressure loss of the intercooler is almost zero

The stainless steel cooler is adopted, and the air side adopts three ba es to provide a good cooling e ect and greatly reduce the pressure loss of the air.

4,Dry oil-free screw main engine casing adopts oil cooling method

The closed water circuit used for main engine cooling can reach a constant low temperature level, which means fewer gearboxes are required. The dual-stage main engine design with larger throughput can reliably provide 100% oil-free and closer to constant temperature compression. This is mainly due to its constant low temperature, which can be used in demanding applications with ambient temperatures up to 45°C.

High temperature working environment: Long-life components are designed to withstand the highest ambient temperature of 46ºC. Stable rotor, reliable large gear drive system, international technology super coating, durable ball bearing system, stainless steel air seal and unique design Labyrinth seal.

5,Low failure rate and easy maintenance

■ Use PLC to edit the controller: PLC editable controller is tested by decades of practical application. It has strong anti-interference ability, reliable work, low failure rate, easy operation, easy equipment expansion, simple installation, and self-diagnosis function , Easy to maintain.

■ Equipped with a large LCD display, the operation is clear and convenient. When the air compressor needs maintenance or malfunctions, the display will automatically send out a warning to remind timely maintenance or troubleshooting.

■ Reduce lubricant replacement: The industry-leading Mobil Super Lubricant provides up to 8,000 hours of lubricant life, which is 8 times the service life of conventional lubricants.
