A line of PVC and CPVC duct dampers offered in butterfly, gravity, and blast gate types for fume removal applications is available. The backdraft dampers come in three flow control types: butterfly for balancing airflow, a gravity backflow preventer which closes when the air pressure stops, and a blast gate for on-off where space constraints exist. Able to handle corrosive fumes, they are offered in PVC or CPVC construction with flanged, belled, and plain ends, depending upon the version. Available in standard sizes from 4 to 24 inches in diameter, the backdraft dampers provide a corrosion-resistant solution that is compatible with popular fume removal ducts. Sizes up to 80 inches in diameter and polypropylene construction are also offered. Applications include fume and tank hoods and ventilation systems for electro-platers, manufacturers, HVAC, and process requirements.
