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. ( air damper,  volume control damper for duct,  damper handle,  damper quadrant,  volume damper,  motorized volume control damper,  noise damper,  electric air damper,  damper valve,  vcd damper,  duct damper,  motorized damper actuator,  motorized air damper,  air damper actuator,  motorized damper ventilation,  shut off damper,  air duct damper,  air conditioning damper)

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.
