51mm x 114mm AirflexPro Oval Coil (20m) designed to with equal hydraulic performance to AirflexPro Round and is totally interchangeable - This means you can switch from oval to round using compatible transition pieces in the same duct layout with zero leakage, and zero loss in performance. AirflexPro Oval is the optimal solution when routing ducts is required in tight spaces. No other duct system has this technically interchangeable round to oval (elliptical) design.

KEY FEATURES:

• The duct lining is made from new raw material (not recycled) and is anti-static, non-porous and odourless, this lining helps reduce dirt deposits and has other characteristics such as low air-flow resistance and has high sound absorption.
• Access panels on the distribution boxes so that the ducting system can be easily cleaned out. (As required and stated in the 2010 Domestic Ventilation Compliance Guide).
• No noise transfer (talking, music etc) between rooms (As required and stated in the 2010 Domestic Ventilation Compliance Guide).
• No noise generated by high volumes of air being pushed or sucked down ducting (common with branch systems).
• No joins in ducting so it cannot become dislodged if knocked or disturbed e.g., in loft spaces.
• Quicker and easier to install compared to traditional branch systems.
• Bespoke insulation available for unheated areas.
• Metal attenuated (noise absorbing) distribution boxes – very robust and durable, various sizes.
• Also available in round Ø75mm (OD)/ 63mm (ID) in both red (9041130) and blue (90001379).
