SOLUTION PRODUCTS > Certified Back Drafts
PROBLEM: Pulsation, from the cleaning of filter media or other pressure increases, can cause pulsation back into the plant or building through the duct system. Stopping this pulsation at the source is critical. SOLUTION: K&B Back Draft Dampers are designed with a counter balanced flap that easily opens with the flow of air, but quickly and tightly closes when the air flow is reversed. Thus, closing off the building. Units are constructed of heavy duty 3/16" steel to withstand high pressures.
