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
