The unit includes an integrated screen and an 11-inch tail pipe for connection to ductwork. This type of louvered intake vent allows fresh outside air to enter a structure while the screen prevents insects, debris, and other foreign material from entering the air stream. HVAC technicians and general contractors install this fitting as part of combustion air, exhaust, or fresh-air ventilation systems where a flush wall or soffit termination is required.\u003c\/p\u003e\u003cp\u003eThe 604WTP is suited for residential and light commercial installations where a 4-inch duct termination is needed. It is commonly installed through exterior walls, soffits, or rim joist areas to serve mechanical ventilation, dryer venting supplement, or air intake functions. The white finish blends with standard trim and siding. The tail pipe extends into the wall cavity, simplifying connection to round duct or flexible duct without additional adapters in most standard-depth applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch opening matches standard residential round duct sizing\u003c\/li\u003e\n\u003cli\u003eIntegrated insect and debris screen protects the air stream\u003c\/li\u003e\n\u003cli\u003e11-inch tail pipe allows direct connection to ductwork within typical wall depths\u003c\/li\u003e\n\u003cli\u003eWhite plastic construction resists corrosion and moisture\u003c\/li\u003e\n\u003cli\u003eLouvered face provides directional airflow control at the termination point\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for 4-inch round duct terminations in residential and light commercial ventilation systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by HVAC technicians or general contractors following local mechanical codes. Shut off any associated mechanical ventilation equipment before cutting the penetration and securing the fitting. Seal around the exterior flange with an appropriate weatherproof caulk to prevent water intrusion. Ensure the louver orientation and screen are unobstructed after installation and verify airflow direction meets the requirements of the connected system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTail Pipe Length\u003c\/strong\u003e: 11 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.7 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10 per unit of measure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LAMBRO INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 604WTP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LAMBRO INDUSTRIES","offers":[{"title":"Default Title","offer_id":51525454135602,"sku":"604WTP","price":109.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6fbf5ba9f71ceb6c1e9d6967de5d2f88.jpg?v=1785474227","url":"https:\/\/voomisupply.com\/products\/lambro-industries-604wtp-air-intake-louver-vent-4-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
