FIELD: heat engineering.
SUBSTANCE: invention relates to the field of heat engineering and can be used in a supply ventilation unit for indoor installation. In the supply ventilation unit, which includes an air intake unit, which includes a casing made with the possibility of mounting on the outer surface of the building, pneumatically connected to the air inlet channel and the external environment through the inlet grille and the ability to accommodate a filtration unit, the volume of which is pneumatically connected to the volume of the air inlet channel through the area of static pressure; the cross-sectional area of the static pressure region near the filtration unit by a plane perpendicular to the direction of air movement is greater than the cross-sectional area of the air inlet channel at the junction with the air intake unit; while the casing is made with the possibility of removing at least part of the filtration unit.
EFFECT: simplification of service.
