Characteristic

Air bearing centrifugal blower is a new concept blower developed byexperience of military aviation turbine mechanical design. lts basicprinciple is that the high-speed permanent magnet synchronous motorcontrolled by air suspension bearing and frequency converter directlydrives the coaxial centrifugal impeller to do work,creating a new era ofthe ultimate energy-saving and environment-friendly blower.

Simple/low cost

The use of air suspension bearing technology eliminates the need for lubricants and regular bearing changes, only regular filter changes are required.

Use & control

Motor revolutions, pressure, temperature and flow rate are displayed on the touch screen, which makes it easy to change and enter data.

Energy saving

(Energy saving effect can reach 45%) The compression part adopts high efficiency design and high efficiency motor, the comprehensive efficiency can reach more than 70%.

composition

Simple construction, small size, lightness and refinement, reduced floor space, easy to move and install.

low noise & non-vibration

Simple construction, small size, lightness and refinement, reduced floor space, easy to move and install.

Oil Free

The air foil bearings require no lubricant maintenance and are supplied with pure, oil-free air.
