Advantages of XTB Blower
(1) Energy-saving, high efficiency
Air bearing turbo centrifugal blower adopts air foil bearings, direct-connection technology, high efficiency impeller and motor. No additional friction will occur, and motor power consumption is automatically adjusted according to the output airflow capacity (adjustable range 20-100%), so the energy-saving effect is remarkable.
(2) Low noise
Adopt air bearing and direct-connection way without mechanical contact. Noise is lower than 80dB- @ 1.5m, so there’s no need to install acoustic enclosure.
(3) No oil, no vibration
Air quality reaches ISO 8573-1 0 grade without vibration, so anti-vibration work is not required.
(4) Convenient maintenance
Without gearbox and oil-lubricated bearing of traditional blowers, high and new technology is introduced for convenient maintenance
