Ventilator for building with deflector - has double casing with complementary air entrance and directed exit with dust filter fixed by gasket to building deflector

摘要

The ventilator has a rigid casing (1) containing an air entrance (1a) for flow from the mouth (3) of the system. An air exit (1b) aperture is directed towards the building interior. Walls (6,7), complementary, or part of the casing, produce an interior chamber, with an entry (8a) related to the air entry. An exit (8b) similarly relates to the casing exit. A filter (4) captures particles in the air from the chamber exit. The casing is fixed (9) around the mouth with an airtight gasket, surrounding a deflector (10), which projects into the chamber. USE/ADVANTAGE - For buildings with fan ventilation. Avoids air draughts and soiling, without need to alter existing system.
