Deflect hsm4b/24 Fresh Air Intake 6 Inches

Product Description

The DEFLECT hsm4b/24 is a 6-inch fresh air intake designed for residential and light commercial HVAC applications. Fresh air intakes draw outdoor air into the ventilation system, supporting proper air exchange and indoor air quality. This part is installed by HVAC technicians as a duct system component, typically at an exterior wall or roof penetration. The 6-inch diameter suits standard duct trunk and branch configurations commonly found in forced-air systems. Its compact form factor and straightforward connection profile make it a practical replacement or new-installation component for ducted ventilation work.

This fresh air intake is suited for residential forced-air heating and cooling systems where controlled outdoor air introduction is required. It fits into duct systems that call for a 6-inch opening at the intake point. Typical installations include supply-side fresh air makeup connections and mechanical ventilation strategies in both new construction and retrofit scenarios. HVAC technicians routinely specify this type of component when upgrading or repairing ventilation systems to meet current air-exchange requirements.

Installation Notes

Installation should be performed by a licensed HVAC technician. Power the air handling system down completely before beginning duct work at the intake location. Verify that the installation meets local mechanical code requirements, including any applicable ASHRAE 62.2 ventilation standards for residential systems. Seal all duct connections with code-approved mastic or foil tape to prevent air leakage at the intake joint.
