Description

  • The Primex WC4B Polymer Resin Wall Exhaust Vent Cap is an industrial-grade, commercial-grade equipment component engineered specifically to ensure weatherproofing and smooth high-velocity air exhaust across demanding residential bathroom fans, dryer runs, and light commercial ventilation ports.
  • Fabricated from a premium UV-stabilized impact-resistant engineered polymer resin casing, this high-performance component handles intense solar heat loading and coastal humidity variables with absolute structural integrity while permanently resisting paint chipping, plastic brittleness, and winter freeze-cracking.
  • The innovative gravity-assisted damper flapper and integrated downward drip lip significantly improve external water diversion and backdraft defense parameters to smoothly handle heavy rainstorms and high wind gusts without causing cold-air backwashing, exterior wall staining, or bird intrusion.
  • Ideal for licensed ventilation installers, mechanical contractors, and exterior building technicians, this durable wall cap features an extended 4-inch connection collar and a generous mounting flange to rapidly execute clean, direct field installations, maximize overall energy efficiency, and permanently eliminate expensive customer leakage callbacks.
