Volume Damper

MATERIAL

• • • Extruded Aluminum or galvanized steel.

CASING

• • • Extruded Aluminum or galvanized steel for upper and side frames with different case depth

BLADE

• • • Aero foil blade made from Extruded Aluminum or 3-Groove bended blade for Galvanized steel construction.

QUADRANT HAND

• • • Steel or plastic handle in different sizes to obtain the required momentum suitable for the volume size.

GEARS

• • • Made from specific plastic temperature resistance resistance 70°C to drive opposed blade mechanism.

FREE AREA

• • • max 80%

FIXING SYSTEMS

• • • The frame of the damper has been designed in order to be flanged connection in ducts or other flat surface .

FINISH

• • • Standard mill finish or powder coated .

Aluminum volume damper

• • AIROFOIL 102:opposed blade damper gear operating involving air foil blade with the mentional dimensions .
  • AIROFOIL 95:opposed blade damper gear operating involving air foil blade with the mentional dimensions and with rubber sealing in order to reduce leakage .
  • AIROFOIL 108:opposed blade damper gear operating involving air foil blade with the mentional dimensions and with rubber sealing in order to reduce leakage put the difference between this type and the other types is that the drive gear mechanism is hide inside the frame which providing a maximum free area of 85% .

MOTORIZED VOLUME CONTROL DAMPER

• • MOTORS:As a standard: Belimo models used with our product.

TYPES OF MOTORS

• • Open / Close type without spring return function.
  • Open / Close type with spring return function.
  • Modulating motor.

Steel volume damper

U-Chanel frame type for duct flange mounting or flat surface suitable for (high – medium – low ) pressure application .

MATERIAL

• • The Dampers are made from galvanized steel .

CASING

• • 4 parts of formed galvanized sheet metal GA .16(1.5mm thickness) , welded together to obtain rigid construction .

BLADE

• • Galvanized sheet metal GA.16 (1.8 mm thickness) , formed with three grooves to strengthen the blade in order to resist pressure .

AXLE

• • 1/2 ” round galvanized steel bar bolted to the blade

SLEEVE

• • Round brass.

HANDLE

• • Hand quadrant for manual operation.

FINISH

• • Standard finish galvanized or powder coated .

OPERATION TYPE

• • PARALLEL BLADES: connected by side linkage of galvanized steel concealed in the U-Channel side frame . Parallel blades offer rapid air response to blade movement but divert air flow to one side of the duct .Blades rotation is in the same direction and is best suited for on and off application.
  • OPPOSITE BLADES: two sets of opposed blade connected by side linkage of galvanized steel concealed in the U-Channel side frame opposed blades provide non diverting air flow and reduce turbulence ,which is important when the damper is used in front of fans or coils . the opposed blade damper require a lower opening torque

MOTORIZED STEEL VOLUME CONTROL DAMPER

• • The same construction but the blade mechanism derived by a motor .

ROUND VOLUME CONTROL DAMPER

The round control damper with a full circumference blade seal for low leakage. It is designed to replace a section of the duct work where a damper is needed.This construction to ship actuators installed on the damper. The damper can be constructed of stainless steel if required. The rolled duct stops make for ease of installation and sealing the duct work to the damper.The damper is one of the lowest leak dampers in the industry .

APPLICATIONS

Generally used for applications in round ducts and pre-insulated ducts to control air flow rate.

MATERIAL

• • The Dampers are made from galvanized steel sheets or stainless steel as required

CASING

• • (0.8 mm) Gage 22 rolled galvanized steel sheets .

BLADE

• • (0.8 mm ) Gage 22 circular blade galvanized steel full circumference neoprene blade steel .

QUADRANT HAND

• • For manual operation made from galvanized steel .

AXLE

• • 1/2 ” round galvanized steel bar bolted to the blade

SIZES

• • 80mm Diameter up to 630 Dia. in single blade construction .

FINISH

• • Standard galvanized finish or powder coated

MOTORIZED ROUND VOLUME CONTROL DAMPER

• • The same construction but the blade mechanism derived by a motor .
