FFU et équipement de purification de l'air terminal
Module d'alimentation en air propre intégré HEPA Système de grille de plafond
A complete ducted ceiling terminal combining an inlet damper, pressure-equalizing plenum, sealed HEPA or ULPA filter and room-side diffuser in one cleanable module.
- Balanced Ducted Supply
- HEPA or ULPA Final Stage
- Room-Side Test Access
- Interchangeable Diffuser
Introduction de produit
The integrated HEPA clean air supply module receives conditioned air through a top or side duct collar and distributes it across a sealed final filter through an internal equalization plenum. A balancing damper can be adjusted from the cleanroom side, while separate upstream pressure and aerosol ports support routine checks without opening the ceiling void. The module includes the filter seat, retaining hardware and removable perforated or radial diffuser, so the complete air terminal can be installed as one coordinated ceiling component rather than assembled from unrelated parts on site.
Key Features
Room-side damper access allows supply volume to be balanced after ceiling installation.
Separate upstream pressure and challenge ports keep routine test connections accessible below the ceiling.
A quick-release face accepts different diffuser patterns without replacing the sealed plenum.
Préoccupations du client produit
A cleanroom supply point must convert uneven duct air into a sealed, testable and draught-controlled final discharge without consuming unnecessary ceiling space.
High inlet velocity loads one part of the HEPA face and leaves another area underused.The pressure-equalizing plenum diffuses the incoming jet before it enters the final filter.
Ceiling access is obstructed by services when the airflow damper needs adjustment.A room-side adjustment mechanism reaches the inlet damper through the removable diffuser.
Temporary hoses for filter testing are routed through the occupied ceiling void.Dedicated room-side pressure and aerosol ports connect directly to the upstream plenum.
One discharge pattern creates local draughts after the room layout changes.Perforated, swirl or radial front plates can be exchanged while the terminal body remains installed.
