Airflow’s HVS10/6 low-cost continuous-ventilation unit can serve up to six duct runs using Airflow’s Airflex Pro 75 mm round ducting. This low-leakage ductwork is Appendix Q eligible.
Like other Airovent units, the HVS10/6 is small enough to be located in the loft or a cupboard to provide low-noise extraction from wet rooms such as kitchens, toilets and bathrooms. Natural ventilation via windows or doors replaces the extracted air.
Airflex Pro ducting is quick and easy to install, with up to 70% time saving on site compared to rigid or spiral ductwork. It can be squeezed into narrow joists or run in concrete screeds.
