The Bovema AGH ventilator is an aluminium wall extract unit, with an axial flow fan, designed to remove large volumes of air with low energy consumption. It is particularly suitable for the exhaust of free air from large buildings, and has low system resistance.
The aerodynamic aluminium wall cowl prevents water penetration even when the fan is not operating, and the internal airflow shutter provides further weather protection to prevent air losses when closed.
The lightweight aluminium construction is suitable for installation into all types of wall construction and various types of vertical glazing systems.
The AGH ventilator is manufactured to NEN-EN-ISO 9002 quality control standards, from high quality corrosion resistant aluminium, for long life and low maintenance.
The electric motor is directly connected to the fan shaft to minimise transmission losses, and the fan extracts the air, which is discharged via the horizontal cowl. This air cools the fan motor.
Where fitted the optional non-return shutters close when the fan stops, to cover the opening and prevent air losses through the ventilator, in winter or at other times when ventilation is not required.
The external screen prevents birds or rubbish from entering the ventilator.
The AGH ventilator is suitable for continuous operation.
Bovema has its own team of specialists that ensure the calculation and NCP certified installation of all systems without involving any sub-contractors in the process.
The AGH ventilators are fully assembled and tested prior to delivery.
