Model
Material
Product external casing is manufactured from galvanized sheet, its internal components are from galvanized and aluminium sheet.
Usage
Mechanical constant flow damper achieves flow rate control both independently and at the same time without adhering to any electrical power. It adjusts the required air flow rate with its spring operated mechanism according to the pressure change by itself. Mechanical constant flow dampers are used for supply or exhaust of required fresh air with constant flow rate to places in ventilation systems. They are constant flow units which are operating by making its control mechanically by itself. They are used for supplying constant fow rate control at ± %10 deviation ratio without requiring any servomotor. The required air flow rate can be changed via an allen wrench on the unit easily. They are produced as with circular and rectangular sections. It is more economic than motorized types due its being mechanical. It is used in pressure range of minimum 50 Pa and maximum 1000 Pa and air velocity range of 2 - 10 m/s.
