The invention relates to a device for filtering air and creating an overpressure in a closed or semi-closed space, comprising at least one housing, comprising at least one air inlet and at least one air outlet, at least one ventilator for taking in air in particular via the at least one air inlet, at least one filter for filtering air which is drawn into the device, wherein the at least one ventilator and the at least one filter are received within the at least one housing and wherein the at least one housing is configured such that air drawn into the device by the at least one ventilator is pushed through the at least one filter towards the at least one air outlet.
Device for filtering air and creating an overpressure in a closed or semi-closed space, comprising:
Device according to any of the previous claims, wherein at least part of the at least one housing is substantially cylindrically and/or conically shaped.
Device according to any of the previous claims, wherein at least part of at least one filter is substantially cylindrical and/or conical.
Device according to any of the previous claims, wherein at least one filter comprises a HEPA filter.
Device according to any of the previous claims, wherein at least one air inlet extends over a circumference of the at least one housing.
Device according to any of the previous claims, wherein at least one air inlet is formed by a radially extending slit formed by at least part of the at least one housing.
Device according to any of the previous claims, wherein at least one ventilator is an axial ventilator.
Device according to any of the previous claims, wherein at least one ventilator comprises at least one fan blade and preferably multiple fan blades.
Device according to any of the previous claims, comprising at least one barrier element positioned at a distance from the at least one ventilator.
Device according to any of the previous claims, comprising at least one drive for driving the at least one ventilator.
Device according to any of the previous claims, comprising at least one control unit for controlling the rotational speed of the at least one ventilator.
Device according to any of the previous claims, wherein the at least one control unit is configured to control the rotational speed of the at least one ventilator based on its capacity.
Device according to any of the previous claims, wherein at least part of the housing defines a compartment which is positioned between at least one air channel defined by the at least one filter and at least one air outlet.
Device according to any of the previous claims, comprising at least one prefilter positioned between at least one air inlet and at least one ventilator and configured to filter at least part of the air.
Device according to any of the previous claims, wherein the at least one housing is a modular housing.
Device according to any of the previous claims, wherein at least one filter is removably attached within the at least one housing.
Use of a device according to any of the previous claims.
