Abstract

Device comprising a filter (10) associated with a ventilation air intake. According to the invention, this device also comprises a blocking component (12) of impermeable material designed to press against the filter (10) to partly or completely cover it, said blocking device being associated with means for controlling its movement, said movement control means being connected to a computing device (18) which receives information consisting of the pressure or flow rate at the outlet of the ventilating unit (2) and which takes action depending on the information transmitted to it to maintain the pressure at a constant value by acting on the position of the blocking component in relation to the filter and/or on the advancement of the filter. Application to the ventilation of premises.
