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

Clean Air’s expert team will guide you to the ductwork and vent system that best suits your needs – 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 to ensure 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 such as pharmaceuticals, life sciences, laboratories, chemical processing, and waste water treatment.

Our ductwork can be reinforced with GRP (glass fibre reinforced plastic) upon request by our in-house team. We can tint the GRP to any RAL colour. This facility is useful for clients who wish to colour match fans and ducting to brickwork on older and listed buildings. White tinting is popular for systems installed in hot countries. The white pigment reflects the heat and the GRP coating itself provides a shatterproof layer to fan casings and pipework.

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 duct can be fabricated to suit your dimension requirements and to normally accepted specifications such as DW/154.
