Multi-leaf dampers in galvanized steel 

Equipped with outer mechanism and brass bearings

• For airstream regulation in ventilation and airconditioning systems
• Temperature resistant applications up to 250°C
• RWA installation

• Galvanized steel blades, frame, and square axle
• Outer mechanism
• Air-tight brass bearings for temperature ranges upto 250°C

• Galvanized steel

• Galvanized steel aerodynamic designed regulation blades of 165 mm width
• Galvanized steel square axle
• Galvanized steel housing with depth of 175 mm and flange of 30mm, made out of 2 vertical panels with air tight brass bearings and 2 horizontal panels, all welded together
• All dampers are made to measure. To obtain the exact height of the damper when in-between sizes are ordered, the upper and lower frame will be bended towards or away from the middle of the damper(see drawing), to make a execellent fit with as much as possible standard fitted blades. Due to this fact the free area of the damper can become less than the opening of the LXH dimension.

• To be mounted between rectangular ducts with flanges of 30 mm
• To be surface mounted on wall, floor or ceiling

• The multi-leaf volume control dampers with high temperature resistance shall be of the standard type in galvanized steel with counter-rotating blades, outer mechanism, brass blades and square axle.
•  ATC Type JS 251BS + ML

• JS 251BS + ML, 1400, 1500, C30 + MCS-251/255

Explanation
