Anemostat Vents A 100 VRF is used to distribute air directly into the room. Suitable for both supply and exhaust ventilation systems. Installed in a suspended (suspended) ceiling, sometimes in a wall. The convenience of using the anemostat is due to the ability to adjust the air flow that passes through the air distributor. The air flow can be adjusted by rotating the inside of the poppet valve, thus changing the 'live cross-section' and air flow.
Material
Made from ABS plastic or polystyrene. The material is durable, resistant to sunlight, and impact resistant.
How to install
The plastic anemostat is connected with a branch pipe to a flexible or rigid air duct with a diameter of 100 mm. Installation to the ceiling is carried out using spacer plates and a mounting flange located on the inside. Spacer legs hold the anemostat in the suspended ceiling; the flange allows you to tightly press the anemostat body to the material of the suspended ceiling.

Air flow and pressure loss
The diagram displays the pressure loss on the anemostat at a certain gap S (mm) between the central part of the anemostat and the landing valve location. When changing the gap by rotating the inside of the valve, the live cross-section of the air distributor changes, as shown in the figure below.
The oblique lines in the diagram indicate this valueSin mm. For example, with a gap of S=2 mm and an air flow of 10 cubic meters. per hour the pressure loss will be 7 Pa. Another example: with a gap of 22 mm and an air flow of 100 cubic meters. per hour the pressure loss will be 11 Pa.
