Applications
Supply Air
Terminal Housings for HEPA filters are used to house and seal HEPA filters into ceilings as part of supply air systems offering the cleanest air.
Typical applications include cleanrooms, pharmaceutical production, laboratories and research units where clean HEPA filtered air is essential.
Extract Air
HEPA Terminal Housings can be used for extract air, preventing contaminated air from escaping a space. Whilst safe change systems should always be considered in these scenarios, a HEPA terminal housing can offer a suitable solution to the isolation of contamination, where filters can be changed within the operational space.
Common scenarios for this concept would be isolation rooms in healthcare, laboratories, or secure post rooms.
Description
HEPA Terminal Housings are designed to be suspended directly above false ceilings, allowing access to change the HEPA filter from within the room by removing the grille. Suitable ceilings are typically, but not limited to, Grid Style or Plasterboard where ductwork services run in the space above the ceiling. Terminal housings can also be mounted on their side to be used in a wall as required.
Spigots on the rear of the unit are available as either Top Entry circular spigots, or a Side Entry sleeved spigots to suit different duct layouts.
As standard Terminal Housings are supplied with 4 Way Blow Diffusers that are painted white. Variations of grille can be arranged upon request including swirl, perforated and egg crate. Securing the grille is often achieved via a removable core to the grille.
A smoke challenge insertion point is installed as standard 1”BSP, along with an upstream pressure tapping point, which can be used for upstream smoke challenge detection. Balancing Dampers and downstream pressure tapping points can be added on request.
HEPA Terminal Housings are fabricated from mild steel ensuring that the case maintains a high level of rigidity to support the HEPA clamping system essential to the correct functionality of the housing. Flanges are flat to suit both rounded or flat neoprene gaskets, and achieve a seal for the filter to the housing to the same efficiency as offered by the HEPA Filter.
