HVAC Regulative Damper

I. Manual Opposed Multiblade Damper CST

• It can be installed directely to the duct, connects with duct for regulating indoor air volume. Made of Galvanized Steel or other steel, it is easy and convenient to operate and install. TDF integrated flange was adopted.

• WxH matches with the dimension of duct.

• Pls inform us the products’ name, model number, specification and quantity when you are going to place the order.
• e.g. Automatic Smoke (Fire) Damper CFHTQ70 1000*400 (W*H) 5pcs

• Specification indicates that damper’s ventilation size W*H, W indicates width of the damper, H indicates height of the damper, actuator was installed at H side; circular damper has diameter ¢D. If no remark in the dimension, the measuring unit should be mm.
• As to the smoke outlet/ air outlet, you need to mark if it is the ventilation size or the outlet size, as well as the position of the access plate. If not, the access plate will be installed at H side.
• e.g. Smoke Outlet CFY400*800, indicates the damper size is 400*(800+200), the decorate side is 460*1050, the access plate will be installed at the 800 side.

• If you have any special demand, pls note:

1. Damper’s color, outlet’s color. (If there is no remark, aluminum material color will be used: Argenteous).
2. If it is with access plate. (If there is no remark, there is no access plate).
3. The length of the remote cable. (If there is no remark, 6m will be used).
4. Other technical specifications that is different from present specification in this catalogue.

Dut to continuous improvement, Comifo reserves the right to modify the product design and specification contained herein without notice. Pls contact Comifo for the most current specification information.

As not only a product manufacturer, but also a machine manufacturer, Comifo makes all kinds of dampers and air duct products by using own-made machines. 

With automatic fire damper frame auto lines (the detail can be found from  FIRE DAMPER FRAME LINK ), fire damper blade auto lines (the detail can be found from FIRE DAMPER BLADE LINK ), fire damper fastening table (the detail can be found from FIRE DAMPER FASTENING TABLE LINK ), we can make hundreds damper per day. It saves much more production time and labors. 

Moreover, beside using our own-made machines, the dampers are installed withour own band damper actuator, PREN. We research and develop damper actuator base on our more than 10 years damper manufacturing experience. The actuator is more cost-effective with high quality. If samples are required, please contact us. 

Comifo supplys fire damper and air duct products all over China, include of our many projects. We are the manufacturer, and the user. We can feedback any problems promptly when using our own machines, or products. It is a big advantages for us to improve our machines and products continueously. Most of problems may happen to customers, we can find and solve before put into the market. 

If customers who want to use automatic equipments to make dampers or ducts, we can help and supply machines and technical instruction. 

Customized machine according to customers' damper design are also available.
