P. STEAM DAMPER SYSTEM
The newest type system is called the
steam damper. It is shown to the
right and it uses a piston with
compressed air to open and close
the steam damper which in turn
allows the air to flow either through
the coil for heat, or under the coil
for cool down. Air supply is 80 PSI
(+/- 10 PSI).
Q. COMPRESSED
AIR REQUIREMENTS
The dryer requires an external supply of air
(2.5 cfm @ 80 psi) on the steam models the
air is necessary to operate the damper system.
On both steam, as well as the gas model, the
air is necessary/required for the blower air jet
operation...to clean lint from the impellor/fan
(squirrel cage type).
