PVC Duct Rain Caps Style B are zero pressure loss protective ductwork fittings used in ventilation, exhaust, and duct systems to prevent precipitation, debris, and animal intrusion. Style B Rain Caps have a unique internal engineering to modify airflow dynamics so air can pass through without a significant loss in pressure. This is known as the zero pressure loss feature. Style B Rain caps also have a long, slender design to improve aerodynamics and reduce wind friction for superior protection in high wind events. These rain caps are made from Type 1 Grade 1 polyvinyl chloride (PVC) and conform to ASTM D1784 standards and Cell Class 12454-B requirements for chemical resistance, durability, and long term outdoor exposure.
Style B Rain Caps are designed for improved functionality in environments with heavier rainfall, high winds, and when preventing pressure loss in the ventilation system is critical. SUPERDUCT® Style B Rain Caps are IPS sizing standard compatible with Schedule 40 PVC duct pipe for ease of installation. Sizes range from 3″ to 24″ to accommodate different duct systems and for project completion across industrial, commercial, and residential applications.
