The characteristics of air-handling units
↘Frame structure
The unit adopts aluminum alloy frame structure or metal frame structure, it has the following features:
A: Good performance in mechanical strength, light in weight, corrosion resistance, beautiful shape and accurate size.
B: Flexible assemblage, very convenient to install, remove and maintenance. Also, it has longer service life than steel structure
↘Fan, motorl
A unit adopts centrifugal fan with both air inlet. The fan runs smoothly in the rigorous static and dynamic balance ̀test.
B: With ball bearings sealed, and functions of pre-lubricating, self-aligning, self-locking, automatic thrust, etc., the fan is maintenance-free in normal use.
C: Fans of a small model unit are driven directly by external sub-motor, no belt, and easy to maintain
↘Filter
Unit filter is coarse plate. Filter material is cleanable convex Nylon net.
Ordering Guide
