Dundas Jafine LH3WXZ Exhaust Hood Vent Deflector 3 Inches

Product Description

The DUNDAS JAFINE LH3WXZ is a 3-inch white polypropylene exhaust hood with a vent deflector flap, designed for terminating dryer exhaust or ventilation ductwork through exterior walls. The cammed louvers pivot freely to reduce sticking caused by lint buildup or weather exposure, and the molded caulk edge gives installers a clean, finished application surface. UV-resistant polypropylene construction protects the cap from sun degradation over time. The unit snaps directly onto aluminum pipe cap assemblies, eliminating the need for lint-trapping staples. It can be painted to match exterior finishes.

This exhaust hood is used in residential ventilation applications where a 3-inch duct terminates through an exterior wall or soffit. Typical installations include dryer exhaust, bathroom exhaust fan terminations, and range hood makeup air outlets. The snap-on and snap-off design for j-channel siding simplifies both initial installation and future replacement without cutting or removing surrounding material. Its compatibility with standard 3-inch aluminum pipe cap assemblies makes it a common service replacement for field technicians and installers.

Installation Notes

Installation is performed by HVAC technicians, plumbers, or general contractors during new construction or service replacement.

Ensure the exterior wall penetration is properly sealed with appropriate exterior-grade caulk along the molded caulk edge to prevent moisture intrusion.
