Electric Constant Air Volume Damper
Introduction
It is a kind of mechanical system powered controlled for constant volume system. The
volume flow rate controller operates without an external power supply. A control blade
supported in bearing is positioned by aerodynamic forces such that a pre-set volume
flow is maintained constant over the entire differential pressure range.
Features:
1. Mechanical system powered, no external power supply
2. For supply air or extract air.
3. Operating temperature 10~50℃
4. Differential pressure range of 50~950Pa
5. It can be installed in orientation with horizontal blade shaft.
6. Correct functioning even with unfavourable inlet and outlet flow conditions
7. Volume flow rate adjustment via external scale, scale accuracy approx: ±4%
Material:
Casing and control blade in galvanized steel sheet.
Stainless steel leaf spring.
Polyurethane bellows.
Bearings with PTFE lining.
