Consequence
Our Factory
Consequence
Air leakage does not meet the requirements
Excessive air leakage from fire dampers will cause major safety hazards
Airtight performance is selected according to requirements
The air leakage meets the requirements, and the product is safer to use
The installation accuracy of the connecting rod between the baffles is not enough
As a result, when the fire damper is closed, the shutter still cannot be completely closed.
The connecting rod between the baffles is installed with high precision
When the fire damper is closed, the shutter can be fully closed.
The fire rating does not meet the requirements
It is easy to leave a safety hazard
Select as required
Product use more assured, longer service life
The thickness of the damper shell does not meet the requirements
The casing is prone to breakage
The thickness selection of the damper shell The regulations of each classification society are consistent with the SLOAS requirements
The shell meets the requirements, and the damper can be used for a longer time
