Pressure Drop Performance Test

The pressure required to discharge the set air volume through the supply or exhaust damper is referred to as pressure drop.
depending on the damper blade shape and opening angle of each manufacturer's product, not conforming to AMCA standards. The performance test for pressure drop serves as a criterion for the design performance data of duct resistance design.
