Mesh-face HEPA outlets
Terminal HEPA supply outlets with a mesh diffuser face for cleanrooms, combining plenum box, final filter and diffuser in one unit for new builds and retrofits.
Description
A mesh-face HEPA outlet is a ceiling or wall terminal unit for cleanrooms, built as a plenum box with a final HEPA filter, a filter collar and a mesh diffuser face with a perforated diffusion plate. The built-in HEPA stage removes dust particles, bacteria and other contaminants from the supply air, and the mesh face spreads the air evenly to avoid dead zones or local over-blowing. Airflow is set at 500 to 3000 m3/h per unit with a face velocity of 0.9-1.1 m/s. Two casing depths are offered — 380 mm with a 90 mm filter, and 500-600 mm with a 220 mm filter — and an optional down-adjustment damper can be fitted for airflow balancing. The design suits new builds and retrofits across cleanliness classes in pharmaceutical, healthcare, electronics and chemical facilities.
Features
- Plenum box, final HEPA filter, filter collar and mesh diffuser face in one terminal.
- Even air distribution across the mesh face at 0.9-1.1 m/s face velocity.
- Two casing depths: 380 mm with 90 mm filter, 500-600 mm with 220 mm filter.
- Four sizes per series with airflow from 500 to 3000 m3/h.
- Optional down-adjustment damper; detachable construction for filter replacement.
Applications
- Cleanroom supply-air terminals in pharmaceutical and healthcare facilities
- Electronics and chemical cleanrooms
- New-build and retrofit projects across cleanliness classes
