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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6-inch diameter fits standard duct sizing for residential and light commercial systems\u003c\/li\u003e\n\u003cli\u003eDesigned as a fresh air intake for controlled outdoor air introduction into ducted HVAC systems\u003c\/li\u003e\n\u003cli\u003eCompatible with typical forced-air duct configurations as a replacement or new-installation part\u003c\/li\u003e\n\u003cli\u003ePart of the DEFLECT HVAC room air parts and accessories product line\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit fresh air intake for ducted HVAC ventilation systems requiring a 6-inch connection point.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation 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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Fresh Air Intake\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DEFLECT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: hsm4b\/24\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DEFLECT","offers":[{"title":"Default Title","offer_id":51162260603186,"sku":"HSM4B\/24","price":23.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/306258027.jpg?v=1778894370","url":"https:\/\/voomisupply.com\/products\/deflect-hsm4b-24-fresh-air-intake-6-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
