Variable and Constant Air Volume Precision Dampers
|ATG - Airtight Heavy Duty Control Dampers with Electric Actuator|
ATG Damper Data Sheet ... (PDF)
The ATG square or rectangular Dampers are airtight to DIN 1946 Part 4. They are manufactured in 100mm height and 50mm width increments and are equipped with medium or fast speed actuators either electric or pneumatic with Atex certificate on request The large metal internal die cast wheels provide a positive damper movement with very little hysteresis ideal for room or duct pressure control. The dampers are supplied in galvanised sheet metal but can also be made in stainless Steel. Epoxy coating is an optional. The picture shows a galvanised damper fitted with a CMR motor which has a rotation speed of 15s for 0-90 degrees at a torque of 20 Nm and is IP65. Actuators in access of 50Nm with a speed of 15s or faster are available for the larger size dampers. The dampers are supplied with a standard Frame of 30mm.

|CVQ - Mechanical Rectangular Constant Volume Controller|
CVQ Constant Volume Damper data sheet ... (PDF)
The CVQ rectangular mechanical constant air volume dampers are manufactured of galvanised sheet metal and are supplied ready for installation. The air volume set point is factory adjusted and can be easily changed on site via the set point adjustment dial. There is a built in shock absorber which eliminates any bouncing of the mechanical air volume control damper through air turbulance. The shock absorber provides clean air volume flow at all times. The CVQ works between a minimum back pressure of 50 Pa and a of maximum is 1000 Pa. If a constant volume has been adjusted to 500m3/h and the operating pressure is 250 Pa and the pressure changes suddenly to 1000 Pa, the damper would adjust instantly to always provide 500 m3/h regardless of the changing back pressure. A motor driven unit is available to change the set point from remote which is ideal if a variable volume control is to be achieved. The motor can be used in conjunction with the DPC controllers and is ideal for night set back energy saving.
