L. COMPRESSED AIR REQUIREMENTS
The model MD-170 dryer requires an external supply of compressed air of 2.5 cfm at 80 PSI (552 kPa). For
Steam Models, compressed air is necessary for the air operated steam damper. On both the Steam Model as well
as the Gas Model, compressed air is necessary/required for blower air jet operation...to clean lint from the
impellor/fan (squirrel cage).
1. Air Requirements

achieved.
