PVC Duct Blastgates

PVC duct blastgates are piping components used to regulate or block flow in ductwork and ventilation systems. The fittings are designed to act as valves or gates that can be manually opened and closed to control the flow of air, dust, and other materials such as exhaust, work fumes, and gaseous media. Blastgates feature a 3-position locking pin and a PVC plastic sliding gate that provides open, half-open, and closed positions of airflow control. This allows for the regulation of air or particulates for applications such as ventilation, dust collection, and environmental control within various industrial and HVAC (heating, ventilation, and air conditioning) systems. PVC duct blastgates are used to improve the efficiency of air handling systems by selectively controlling airflow. The blastgates are made from corrosion resistant PVC thermoplastic and are suitable for ventilation setups and work settings that handle chemical vapors, fumes, exhausts, or moisture. 

These are USA made PVC duct blastgates built by Harrison Machine and Plastic under the trade name SUPERDUCT®, one of the nation’s top manufacturers and brands of thermoplastic ductwork. SUPERDUCT® blastgates are to be used with air and compatible gaseous media in open air, non-pressurized applications only. They are not for use in pressure systems, with liquids, or with known incompatible chemicals. Always verify chemical compatibility prior to use. 

PVC duct blastgate sizes range from 2″ to 24″in Iron Pipe Size (IPS) diameter. Large duct blastgates are available on request in a range of sizes up to 60″ in diameter. The fittings come with belled end socket connection types. For installation, a professional quality PVC primer and cement is recommended on duct fittings up to 14″ in size. Hot air welding is recommended for duct fittings larger than 14″ in size.

PVC duct blastgates are manufactured from industrial grade PVC resin per ASTM D1784 standards. This ensures a superior performance fitting that meets professional standards for uniform quality, high purity, and reliability in service.
