In-Line Filter Housings

IN-LINE HVAC & HEPA FILTER HOUSINGS are used where enhanced air filtration is required. In-line filter housings can be installed on supply-air ductwork in order to protect a room or area, and they can also be used on return or exhaust ductwork to filter airborne contaminants generated by a process.  As the name implies “In-line Housings” are sheet metal enclosures that house modular filters and are placed with duct-connections either on one end or both ends of the filter housing. These sheet-metal enclosures (housings) have one or two doors at either side of the housing, used to install the modular filter elements. These filter housings usually have gaskets and/or mechanicalsealing-mechanisms to eliminate air bypass.

Side-access (in-line) filter housing construction is typically16-gage galvanized-steel, but optional materials include aluminized-steel or stainless-steel. Material of construction will depend on the application and the physical location of the filter housing.  Housings typically have separate tracks to accommodate ASHRAE MERV8 (or higher) prefiltration, followed by higher efficiency ASHRAE filters or maybe HEPA (High Efficiency Particulate Air) or ULPA (Ultra-Low Penetration Air) filters. These housings can also be paired with High-Efficiency Gas-Phase Air (HEGA) filters in series for applications where particulate contaminants and gaseous contaminants need to be abated.

For more information on HEGA (typical carbon or impregnated carbon) filtration, see our next Solutions section.
