This diffuser measures 14 x 8 inches and delivers a 2-way deflection pattern, making it a reliable choice for HVAC technicians and mechanical contractors who need consistent, even airflow across a space. The unit mounts directly to spiral duct systems, which are common in modern construction for their efficiency and clean aesthetic. The 558513 is engineered to work with round spiral ductwork, simplifying installation compared to traditional rectangular duct transitions. With a CFM rating of 756 at 1200 feet per minute, this diffuser handles substantial airflow demands in both light commercial and residential settings. The active face area measures 0.63 square feet, allowing the diffuser to spread conditioned air across a broad coverage zone without creating uncomfortable drafts or hot and cold spots. The 2-way deflection design channels air in two directions simultaneously, improving air mixing and thermal comfort in the occupied space below. At just 1-5\/8 inches in length, the diffuser has a low-profile build that fits neatly into ceiling grids and finished spaces where clearance is limited. HVAC professionals working on new construction, tenant improvement projects, or retrofit installations will find the 558513 straightforward to specify and install. It is compatible with standard spiral duct collars, reducing the need for custom adapters or transitions. The USVH1 Series is a well-known line from Hart Cooley, a trusted name in air distribution hardware, and this model continues that tradition of practical, field-ready performance. Whether you are balancing airflow in an office, retail space, or residential build, the 558513 delivers dependable distribution with minimal installation complexity.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2-way deflection pattern for broad, even air distribution across occupied spaces\u003c\/li\u003e\n\u003cli\u003eCFM rating of 756 at 1200 feet per minute suits light commercial and residential HVAC systems\u003c\/li\u003e\n\u003cli\u003eLow-profile 1-5\/8 inch length fits easily into finished ceilings with limited clearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Hart Cooley 558513 USVH1 Series Universal Duct Spiral Diffuser offers reliable 2-way airflow distribution at 756 CFM for 14 x 8 inch spiral duct applications, combining straightforward installation with consistent performance in commercial and residential HVAC systems.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HART COOLEY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 558513\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: USVH1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 14 x 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeflection Type\u003c\/strong\u003e: 2-Way\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCFM Rating\u003c\/strong\u003e: 756 CFM at 1200 FPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArea\u003c\/strong\u003e: 0.63 square feet\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HART \u0026 COOLEY","offers":[{"title":"Default Title","offer_id":51120964960562,"sku":"558513","price":241.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304881246.jpg?v=1777744461","url":"https:\/\/voomisupply.com\/products\/hart-cooley-558513-usvh1-series-universal-duct-spiral-diffuser-14-x-8-inches-2-way-deflection","provider":"Voomi Supply","version":"1.0","type":"link"}
