Fire damper is a device installed in an air distribution system or an air transfer opening designed to close automatically upon detection of heat interrupting airflow and thereby restricting the passage of fire in the process. Fire dampers are installed in fire rated walls/barriers/partitions (sleeve required) where the HVAC ductwork penetrates ensuring that their integrity is maintained. The location and installation procedure of fire dampers should be in accordance with the widely accepted and recommended standard, NFPA 90A Standard for the installation of Air-Conditioning.

Construction:
Frame:High quality galvanized Iron Sheet of 1.6mm thickness.
Blades:Interlocking type blades roll formed from 1mm thick galvanized steel.
Blade Ramp:Formed from 1.6mm thick galvanized steel with a spring holder.
Springs:2nos. constant force stainless steel springs.
Fusible Links:UL listed fusible links which has fire rating of 165F / 212F.

Description:

• Fire damper frame is made from 1.6mm thk. high quality galvanizedsteel sheet. All welded joints are rust proofed by zinc paint coating. The fire damper blades are roll formed from 1mm thk. galvanized steel. The interlocking type blades are designed with hat shaped reinforcement ridges ensuring strength and stability. The blade ramp is formed from 1.6mm thk. galvanized steel with a spring holder. The ramp is frmly secured to the frame by rivets. Constant force stainless steel springs are firmly secured to the blades and held in place on the ramp. The blades are secured by UL listed fusible links which has a fire rating of 165F / 212F and thus kept out of the air-stream when not in operation.
• The heat responsive links on detection of heat beyond 165F / 212F release the blades from their position. Upon release, the blades which are connected to the springs are pulled down by the springs and get automatically locked on a latch and remains so until reset. These fire dampers are 1 rated up to 1/2 hours rating with low leakage. All dampers are manufactured in compliance to the UL 555 standards and the companys quality control procedures.
• Upon the termination of fire condition, the damper can be re-opened (usually an access door has to be provided for inspection) by simply pulling up the curtain blades and replacing the fusible link.

Fusible Link:

Vertical: UL Listed 165F / 212F fusible link as standard.
