Product 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.
Product 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%
Product Material:
Casing and control blade in galvanized steel sheet.
Stainless steel leaf spring.
Polyurethane bellows.
Bearings with PTFE lining.
