Marine Scrubber Damper with Seal air fan Y- type / T-type of the damper is 100% sealing is achieved by using a high pressure sealing air barrier.
The system works by a fan creating pressure between the discs. This means that no aggressive gas can pass through the damper since the air sealing pressure is higher than the gas pressure.
