4. Specific Difference Between Us and Other Suppliers:

Comparison
Product Picture of other low quality supplier		Product Picture of our factory
Other low quality supplier	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
