Product Introduction

The clean ward supply ceiling combines four independent terminal filter housings in a compact square 2-by-2 array for hospital ward bed zones and other healthcare rooms requiring filtered ceiling supply. Each shallow powder-coated steel plenum has its own top circular duct collar, retained H14 HEPA cartridge and perforated room-side diffuser. Natural-anodized aluminum rails join the modules beneath one continuous perimeter trim, while corner suspension lugs support coordinated installation above the finished ceiling. The arrangement provides broad turbulent-mixing supply without the lighting, surgical-lamp opening or large central compensation device used on an operating-room canopy.

Key Features

Four individually ducted terminal modules distribute filtered air across a compact square ward ceiling footprint.

Hinged perforated diffuser panels provide clean-side access to the filter retaining rails, seal interfaces and test points.

A separate circular inlet above each plenum reduces dependence on one deep common box and supports branch balancing.

Powder-coated exposed faces, slim anodized rails and concealed grille fasteners create wipeable room-side surfaces.

Customer Product Concerns

A ward supply terminal must deliver clean air across the occupied bed zone while fitting limited ceiling space and remaining serviceable without dismantling the complete array.

A single small ceiling outlet can create a concentrated jet while leaving weak circulation around the patient zone.Four perforated diffuser faces spread supply over a broader square area and add terminal resistance for more even room mixing.

Ceiling-side filter replacement may disturb services above the ward and require removal of finished ceiling components.Each hinged room-side diffuser exposes one retained HEPA cartridge so an individual module can be accessed below the ceiling.

Shared plenums can make branch balancing and fault isolation difficult when several filter faces serve one bed zone.Four dedicated top inlet collars allow the corresponding terminals to be connected and balanced as defined branches.

A bulky surgical canopy can consume unnecessary ceiling space and introduce lighting or equipment interfaces that a clean ward does not need.The compact four-module layout omits surgical-light openings and integrated luminaires while retaining filtered ward supply coverage.
