ROTARY
VANE BLOWER
Mechanism:
The rotor is bias
rotated (as the follow diagram) with the vane going in and out inside the slots. The vane are
compelled to attach the inside surface of casing, so that air is absorbed
from inlet and compressed out to the outlet.

Features:
* LOW
NOISE--- Low noise level due to slow R.P.M. and well lubricated. 50~70dB
* HIGH PRESSURE--- High pressure due to
vane-attachment and oil-sealed effect.
* LESS VIBRATION AND PULSE--- Less vibration and pulse due to
slow R.P.M.
and well balanced rotor.
* LONG ENDURANCE AND EASY MAINTENANCE--- Longer endurance due to
solid structure and easy maintenance.
* ENERGY SAVING--- Energy saving due to efficient structure
resulting high
pressure and capacity.
