EEP gastight shut-off rectangular dampers are designed for shutting and balancing air intakes and exhaust ducts.

When closed these dampers meet the requirement of air leakage class to Class 3 of EN1751:2014.

They are suitable for wall and duct mounting for both inlet and exhaust air.

The outer frame of galvanized, painted or stainless steel. The blades of galvanized, painted or stainless steel with double sheet construction. Silicone seals and maintenance free bearings and shafts.

Designed for a maximum dust pressure of 5000 Pa and maximum air velocity of 15 m/s.

Temperature operation up to + 100°C with optional high temperature version operating up to + 180 °C.

These shut-off, gas and balancing dampers meet international standards for rectangular (width B 100-1200 mm and height H 100-1600 mm, 1 mm division) ducts.

Non-standard dimensions are available on request. Standard flange width 27 mm. Flanges and drilling also available according to ISO 15138 standards. Modular construction sizes available up to 2400X3200 mm. Frame thicknesses from 3 mm to 10 mm. Standard frame thickness is 3 mm. Blades are made of two sheets, each of them being 1 mm thick (sandwich design).

Dampers available with following actuators:

Electrical spring return actuator; standard actuators being 24 VAC/DC or 230 VAC or 120 VAC. Depending on the choice of actuator, the actuator might contain built-in open closed limit switches. A wide range of Ex actuators available, including a one second closing time function as an option (for limited sizes).
