A quick and easy to fit system of semi-rigid ducting (Ø90mm (OD) 77mm (ID) x 50M roll in blue) that can result in up to 70% time saving during the on-site installation process, compared to rigid or spiral duct methods.

KEY FEATURES:

• The smooth duct lining is anti-static, which prevents dust build up, antibacterial to improve hygienic conditions 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
• Metal attenuated (noise absorbing) distribution boxes – very robust and durable, various sizes
