Abstract
An improved device and method for checking the adequacy of the rate of air flow in a rotating clothes dryer drum having air flow passing through a first centrally disposed set of perforations and a second set of perforations radially outward of the first set of perforations in the rear wall of the drum into the interior of the drum. The device comprises a rotatable fan and a counter assembly arranged to register the number of revolutions of the fan. There is provided a structure for removably attaching the device to the rear wall of the drum over the first set of perforations in the rear drum wall. A flexible circular skirt having a central opening is removably attached to the rear wall of the drum over and blocking air flow through the second set of perforations. With this device and method the rate of air flow to the clothes dryer drum may be tested by operating the clothes dryer and registering the number of revolutions made by the fan for a period of time and comparing that number to a number determined previously to be an adequate air flow rate.
