We perform fire, corrosion, and air test for our products, and test results shows that our products meets the requirements and standards of:
Our fire dampers are tested for 4 hours and then they pass all leakage and fire test condition of this operation. In addition, we submerge our products in salt solution atmosphere for 35 days, then check if they operate successfully when removed from the immersion tank. Finally, we perform air tests for air control performance to determine leakage and pressure drop.
