Clean Air offers an extensive range of ductwork and ventilation fittings to complement our range of corrosion resistant extract fans for fume cupboards and school fume cupboards. All pipework is manufactured to meet BESA DW/154 Specification for Plastics Ductwork which is the premier specification for PVC and PP-S (polypropylene) ducting.

Clean Air’s expert team will guide you to the ductwork and ventilation system that best suits your needs. From design through to installation – just contact us to discuss your requirements.

Our PVC & PP-s fittings are manufactured in our Manchester factory by our time-served craftsmen. We use blow and injection moulding techniques. This ensures a smooth internal bore in the ventilation ducting which results in minimal air turbulence.

All Clean Air’s PVC and PP-s materials are ideally suited for safely conveying aggressive media in chemically corrosive environments. We have successfully installed our extract systems in pharmaceutical, life sciences, laboratories, chemical processing, and waste water treatment settings.

Glass Fibre Reinforced Plastic (GRP) Options

Where ducting is required in larger sizes, it can be externally reinforced with a GRP laminate by our experienced in-house team. The GRP laminate provides UV protection, increased strength and a shatterproof layer to fan casings and ductwork systems.

We can colour pigment the GRP laminate to any available RAL colour. This is useful for clients who wish to colour match fans and ductwork to brickwork on older and listed buildings.

White pigment is popular for systems that are installed in hot countries as the white pigment reflects the heat.

Bespoke Fabricated Ductwork

With our wide range of equipment and team of highly skilled plastic fabricators, we have the manufacturing capabilities to produce bespoke fabricated ductwork to your specification.

Circular duct diameters are available up to Ø3m. Rectangular ductwork can also be fabricated and tailored to suit your dimensional requirements. We make ductwork routes including radius bends, transformation sections etc. in line with widely accepted specifications such as BESA DW/154.
