products and ensuring efficient operation of machinery.




Cost Effective Oil free Centrifugal Air Compressor For Textile Industry
The air-suspended centrifugal compressor is a Single phase screw air
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 te
mperature 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 centrifugalforce to suspend itself.
●lt has a sim ple 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 oil free air compressor all in one has a simple structure, does not
require traditional mechanical bearings, and is easy to maintain.
●Pure oil free air compressor replaces Roots blower, with lower power
consumption, longer service life and lower maintenance cost.
