Air cooling Single Stage Centrifugal Blowers
Advantages of ATB Blower
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.
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.
Air quality reaches ISO 8573-1 0 grade without vibration, so
anti-vibration work is not required.
Without gearbox and oil-lubricated bearing of traditional blowers, high and new technology is introduced for convenient maintenance

Key Techonogy
1. Air Foil bearing
Air foil bearing is lubricated by air buoyancy. The use of air
instead of lubricant can realize operation under higher temperature
and speed. The advantages of air foil bearing structure include
flexible start-up, low-cost operation, no mechanical friction, no
need for lubrication oil, no vibration, lower noise and long
service life (semi-permanent).

3.High Speed Motor
Adopt motor of high-efficiency up to 95%, of which the speed can be
controlled precisely. The motor is of minimum usable design, fast
speed and air cooling type to achieve high efficiency. Air cooling
is more reliable than water cooling type, because it provides
easier maintenance and promises safer operation.
4. Inverter & PLC
Inverter
Adopt the international famous brand Japan YASKAWA inverter. The
motor can be started up with a small current so as to cut down the
investment on electricity and electric cable. Featured of low
noise, high-efficiency, soft-start type and digital control
efficiency no less than 96%, the inverter is stable and reliable in
operation and can response to rapid load change very fast.
PLC
Adopt the programmable logic controller (PLC) of international
famous brand, of which the automated solutions standard reaches the
world level. The PLC can provide users various solutions from
control to final connection to load. Different with MICOM, the PLC
needn’t MCP. With single unit or multiple units communication
realized by bus wire and center control system, the PLC can lower
cost, improve control capability and safety level.

6. Summing up
Air suspension centrifugal fan with traditional roots blower,
multistage centrifugal blower is different, use air bearing, direct
technology, high efficiency impeller and ultra-high speed motor, to
breakthrough the economic benefits of the higher energy saving
effect.In order to help the ecological environment and stable
technology, provide a good comfortable working environment, can
expect multiple effects.
