1.Electric damper is composed of electric actuator and damper. Modulating type electric damper can modulate the opening degree of the damper, and control the blast capacity. Two positions type electric damper has the on-off and start-up function.
Square louver damper is used in combination with electric actuator. It has small on-off torque, sensitive action, reliable performance, large caliber and light weight. It is widely applied in fan, air conditioner, electric dust collector and various large pipes in industrial fields of metallurgy, building materials, electric power, petrochemical and light industry. It modulates and cuts off dust and gas electrically or manually.
2. There are square damper and round damper.
square damper: X long, 160X130~1000X500 wide
round damper: DN100~DN400
