Acoustic Residential Purge Ventilator

The Sentinel Kinetic range of heat recovery units provide balanced ventilation while recovering up to 91% of the heat from discharged air. This combination of benefits and high efficiency means that draught-free ventilation is achieved at 10% of the cost of traditional ventilation systems.

Two easy to take out filters remove dust to ensure air quality is maintained continuously.

The compact unit is easy to fit and features four air connections to provide ventilation to kitchen, bathroom, toilet and living areas. It is also compatible for use with low resistance ducts and control settings allow constant air flow under all conditions.

Featuring EC/DC motors the Sentinel Kinetic range are classed as ‘zero energy units’ and cost just a few pence a day to run.

The Airtech Acoustic Purge Fan is used to rapidly remove indoor pollutants as well as reducing the impact of overheating in residential dwellings, providing a more comfortable and healthy internal environment for home-owners.

The Acoustic Purge Fan can be used in conjunction with a MVHR unit or independently via a separate switched live connection or 0-10V external sensor input. The Acoustic Purge Fan can be installed in habitable rooms to satisfy Approved Document F Purge requirements (4 air changes per hour). The unit can be installed in conjunction with controllable duct dampers and/ or background ventilators to manage the supply air into the dwelling under purge operation.

The Acoustic Purge Fan is specially treated with acoustic foam to reduce breakout and induct noise, ensuring end-user comfort during operation. As well as boasting a low-profile design, the unit utilises 220x90 spigots to allow easy use of flat ducting in tight void spaces in apartments.
