Abstract
520,641. Ventilators; conditioning air. YOUNGER, A. R. Oct. 26, 1938, No. 30959. [Class 137] A ventilator of the kind described in Specification 491,651, and adapted to be accommodated in a wall, comprises an inlet fan 1 drawing in air through louvres 16 and discharging it into an enclosure through ducts 11 and 12, and an exhaust fan 2 which removes foul air through a duct 15 and louvres 17. The two fans are coupled direct to an electric motor 4 and the assembly may be mounted on a panel 5 fitting within a wall aperture 6. A filter 19 and a heater (or cooler) 20 may be provided. With electrical heating means an automatic cut out is provided which may be a thermostatic control switch, or an air operated switch comprising a vane 21 pivoted at 22 and having a contact 23 so co-operating with a fixed contact 24 that when the fan and electric motor are operative, the air flow in the duct 15 closes the switch which automatically opens when the fan stops, and prevents the resistance 20 from being overheated,
