Designed for mechanical ventilation, this steel in-line air filter Revit family features a central housing body with dual circular duct spigots. Constructed as an enclosed rectangular housing, the unit features tapered transitions leading to opposing circular duct connections for continuous in-line airflow. The exterior presents a clean metallic grey sheet steel finish with an access panel lid secured by corner mounting flanges. Its slim horizontal form allows compact integration within restricted floor-to-ceiling heights or mechanical risers. Both circular spigot adapters extend symmetrically from the lateral sides, shaped to integrate directly into standardized circular ductwork distributions without abrupt airflow restriction or unnecessary turbulence.
The download is a 358 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.
Load this RFA component directly into MEP project environments to incorporate ventilation filtration into mechanical supply runs. Position the family in ceiling voids or utility cupboards, aligning its connection points with rigid circular ductwork systems. Verify spatial clearances around the top access hatch for periodic maintenance and filter replacements during multi-disciplinary BIM clash detection with structural and electrical services.
Suited to urban residential apartments, healthcare clinics, and modern commercial offices, this inline filtration unit is deployed to combat traffic pollution and particulates in heat recovery ventilation layouts. MEP engineers and HVAC coordinators commonly search for nitrogen oxide filters, MVHR carbon filtration units, or inline acoustic and particulate filter housings. The element pairs effectively with balanced ventilation units, silencers, exterior intake louvres, and round spiral duct systems across detailed design and technical documentation stages.
