Abstract

480,305. Apparatus for ventilating rooms. KURTH, F. J. Aug. 19, 1937, No. 22788. Convention date, Aug. 20, 1936. [Class 137] A device for supplying heated air to enclosures comprises an air conduit 1, in which is mounted a fan 9 which draws fresh air through a screened inlet 4, and filter 12, and delivers it through a set of concentric frustoconical rings 20 to ensure uniform distribution, and through a heater 8 to a distributing body 5. The assembly projects through a roof 2, and is provided with a duct 13 through which recirculated air is drawn a valve 14 in this duct being coupled with a valve 15 in the fresh air conduit to control the proportion of fresh to recirculated air used.
