Deflecto dawc Wall Cap Spring Damper 3-1/4x10 in

Product Description

The DEFLECTO dawc is a rectangular aluminum wall cap with an integrated spring damper, designed for use as an exterior duct termination in residential and light commercial ventilation systems. Fabricated from aluminum in a silver finish, this wall cap fits 3-1/4 x 10 inch rectangular duct connections and provides a weatherproof outlet point for exhaust airflow. The spring-loaded damper closes when the system is off, blocking backdrafts, insects, and debris from entering the ductwork. Licensed HVAC technicians and ventilation contractors install this fitting as the final exterior component of a ducted exhaust run.

The dawc is suited for rectangular duct exhaust systems commonly found in range hood ventilation, bathroom exhaust, and whole-house ventilation applications where a 3-1/4 x 10 inch duct terminates through an exterior wall. Its rectangular profile matches standard range hood duct sizing, making it a practical termination cap for kitchen exhaust installations. The aluminum construction resists corrosion in outdoor and semi-exposed mounting conditions.

• Rectangular profile fits 3-1/4 x 10 inch duct connections directly

Compatibility

Designed as an OEM-style replacement or new-installation wall cap for rectangular 3-1/4 x 10 inch ducted ventilation and exhaust systems.

Installation Notes

A licensed HVAC technician or qualified contractor should install this wall cap following local mechanical codes and manufacturer guidelines. Power down or switch off the associated ventilation appliance before beginning installation. The cap should be sealed to the exterior wall surface using appropriate weatherproof sealant to prevent air and moisture infiltration around the mounting flange. Do not install over ducts carrying combustion exhaust gases from Category I or naturally drafting appliances.
