Product Description

Smoke Dampers Series SD

MAIN CHARACTERISTICS : These are powered by a electric motor and can take two operating positions depending on whether the motor is activated or not. The tube and shut-off ball are made of rust-proof material. The motor casing mounts an auxiliary switch that is activated during switching of the damper. The damper has an external lever for manually positioning its shut-off ball and which also indicates its position. These dampers are used to control fumes in gas and fuel oil boiler smoke-stacks. They can be installed in both vertical and horizontal positions. Available in five versions:Ø 130 mm, 150 mm, 200 mm, 225 mm.

OPERATION : Without electric power supply the damper is positioned with the butterfly shut-off valve opening the flow. When electrical power is furnished the motor overcomes the force of the springs and turns the butterfly shut-off valve, closing the passage and keeping it open until electricity is shut-off. When electric power supply is cut out the return spring reopens the passage with the shut-off valve.
