Mechanism
Motor for 60 Hz Units shall be a brushless 1/10 H.P. 3400 R.P.M. with
self-lubricating bearings. It shall be insulated by a resilient mounting and
shall be protected by a self resetting thermal switch. Motor for 50 Hz Units
shall be a universal 1/10 HP. 4200 R.P.M. at rated load with sealed lubricated
ball bearings. It shall be insulated by a resilient mounting. Motor is thermally
protected.
Fan shall be a large. single inlet centrifugal type for
maximum capacity and shall deliver a minimum of 180 CFM. Fan shall be
mounted directly on the motor shaft, and fan and motor unit shall be insulated
from dryer with a resilient rubber mounting to obtain maximum sound and
vibration dampening effect.
The heating element of Nichrome wire shall be side mounted on
the intake, thereby being vandal proof. It shall be protected by an automatic
resetting circuit breaker (25 Amp). which shall open whenever air flow is cut
off and shall close when flow of air is resumed. It shall produce an air
temperature of approximately 145° F (63° C) at 72° F (22° C) ambient room
temperature at the outlet.
A sealed electronic timer will operate the hand dryer for 30
seconds after push button actuation. |
