An oil-free centrifugal air compressor is an advanced solution designed for industries that require clean, high-quality compressed air without the risk of oil contamination. These industrial centrifugal air compressors are ideal for applications where air purity is critical, such as in the food and beverage, pharmaceutical, electronics, and chemical industries.

Compressed Air Compressor Oil free Centrifugal Air Compressor for Industry

The air-suspended centrifugal compressor is a single-stage centrifugal compressor that does not require a gearbox, speed increaser, or coupling. It is directly driven by a high-speed permanent magnet synchronous motor (PMSM), and the motor is controlled by a variable frequency drive(VFD) for speed regulation. The impeller of the compressor is directly coupled to the motor, and the shaft is sus pended on an active air bearing.

High-speed permanent magnet synchronous motor

●lt adopts a high-efficiency permanent magnet synchronous motor (PMSM) with an efficiency≥96%;

●Compact in size;

●lt can achieve precise speed control, up to a maximum of 100,000r/min;

●The motor shaft is directly connected to the impeller, with a trans mission efficiency of 100%;

●The insulation class is H class (maximum temperature res istance of 170*C);

●The motor pole number is 2 poles, suitable for a power supply of AC380V/50Hz

Impeller

●lt is made of high-hardness heat-treated aviation aluminum AL7075 (aviation aluminum) ;

●lt is precisely manufactured through 5-axis machining center, with tolerances kept below 5/1000millimeters; The surface is smooth and clean, and it has higher efficiency compared to cast impellers; LE+R

●lt has high strength, suitable for harsh working conditions of high temperature and high pressure;

●lt is lightweight, with low power consumption;

●The direct connection between the impeller and the shaft can achieve a power transmission efficiency of 100%.

Air bearing

●An air bearing utilizes high-speed centrifugal force to suspend itself.

●lt has a simple structure and does not require auxiliary devices such as lubricating oil supply;

●lt works on a non-contact basis, with no need for maintenance or repair;

●The bearing operates without vibration.

Efficient cooling system

We use a dual-stage air-cooling and self-cooling method with the latest technology, and set up separate air flow channels inside and outside the main unit in a reasonable and ingenious way to maximize the cooling of the main unit. This ensures that the blower system can still operate steadily and reliably even in hot summers.

Features

●Contactless operation, meaning no mechanical bearings that can wear out or fail.

●Low noise output due to minimal wear and vibration.

●High efficiency and energy-saving, thanks to minimal friction loss and the ability to achieve precise. control through frequency conversion speed regulation.
●High reliability with low maintenance costs and a long service life.

●The high efficiency air compressor has a simple structure, does not require traditional mechanical bearings, and is easy to maintain.

●A substitute for Roots blower with smaller power consumption, longer service life, and lower maintenance cost.
