Air Handling Units

Univent, design, manufacture and install bespoke air handling equipment to suit all projects or client requirements. Our air handling units are manufactured utilizing closed cell anodized aluminium pentapost frameworks sized to suit the required panel and insulation thickness, each utilizing ‘knock in’ corner pieces.

Our air handling units can be manufactured with double skinned panelling and either a galvanised steel or leather grain plastisol coated Aluzinc outer skins (other materials & finishes are available on request) with inner skins normally incorporating galvanized sheet steel inner skins with options available for alternative materials or finishes to suit individual project requirements.

These skins would be formed into trays and would normally encapsulate a layer of mineral fibre insulation (thickness & density to suit client requirements). Air handling units for external applications incorporate weather proof roofs, inlet / discharge cowls or louvres & appropriate weather seals. Filtration would incorporate sufficient cells to suit the plant air flow in accordance with the stages & grades required.


  • Frames: Extruded, anodised aluminium, closed section made as standard Plastic coated galvanised sheet steel (GSS), open section made as specials.
