Core Technologies

The air suspension centrifugal blower is a type of single-stage centrifugal blower 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's speed is regulated by a variable frequency drive (VFD). The blower impeller is directly connected to the motor, while the rotating shaft is suspended on active air bearings.

High-Speed Permanent Magnet Motor

● Adopts a high-efficiency permanent magnet synchronous motor (PMSM) with an efficiency of ≥96% and a compact overall dimension.
● Enables precise speed regulation, with a maximum speed of up to 100,000 r/min.
● Features a direct connection design between the motor shaft and the impeller, achieving 100% transmission efficiency.
● Has an insulation class of H (maximum temperature resistance of 170°C).
● Motor pole number: 2 poles, suitable for AC 380V/50HZ power supply.

Ternary Flow Impeller

● Made of high-hardness heat-treated aviation aluminum alloy AL7075 (aviation aluminum).
● Precisely manufactured via a 5-axis machining center, with tolerance controlled within 5/1000 mm.
● Boasts a smooth and clean surface, delivering higher efficiency compared with cast impellers.
● Offers high strength, making it suitable for harsh working conditions of high temperature and high pressure.
● Lightweight with low power consumption.
● Realizes 100% power transmission efficiency due to the direct connection between the impeller and the shaft.

Air Suspension Bearing

● Suspends itself by utilizing centrifugal force generated from high-speed rotation.
● Features a simple structure, eliminating the need for auxiliary devices such as lubricating oil supply systems.
● Operates in a non-contact mode, requiring no maintenance or repair.
● Ensures vibration-free operation of the bearing.
● Guarantees start/stop durability, having passed 20,000 ON/OFF cycle tests.

High-Efficiency Cooling System

Adopts an advanced two-stage air-cooled self-cooling method. Separate and well-designed air flow channels are arranged inside and outside the main unit respectively, maximizing the cooling effect of the main unit. This ensures that the blower system can still operate stably and reliably even in hot summer conditions.

Annotation		For centrifugal fans, the air volume is inversely proportional to the pressure—the lower the pressure, the larger the air volume. Please select the specific model reasonably according to the application requirements.
Annotation		Our company can also provide customized solutions according to customer needs.

This enables isothermal compression of air, lowers compression work, and achieves energy-saving effects, resulting in over 30% energy savings compared to existing oil-free screw compressor products.
● The unique two-stage compression design achieves discharge pressures unattainable by conventional single-stage blowers, meeting end-user air supply requirements.

Industry Applications

● Air suspension centrifugal blowers can be used for gas combustion-supporting, metal oxidation, desulfurization oxidation, fermentation, sewage treatment, etc., and are widely applicable to various industrial sectors including metallurgy, chemical industry, chemical fertilizer, petrochemical industry, food, building materials, petroleum, mining, textile, gas station, pneumatic conveying, sewage treatment and so on.

● They are also extensively applied in industries such as high-density aquaculture, municipal sewage treatment, cement, steel, chemical powder conveying, solidification treatment, desulfurization, electroplating, sandblasting, electronics, food, medicine, papermaking, textile, printing and dyeing, biological fermentation, and air conditioning fresh air systems.
