NOTE: Air considerations are important for proper and efficient operation.
D. FRESH AIR SUPPLY REQUIREMENTS
Air supply (make-up air) must be given careful consideration to ensure proper performance of each dryer. An
unrestricted source of air is necessary for each dryer. An airflow of 400 cfm (cubic feet per minute)
(11.3 cmm [cubic meters per minutes]) must be supplied to each gas dryer. As a general rule, an unrestricted air
entrance from the outdoors (atmosphere) of a minimum of 1 square foot (0.093 square meters) is required for
each dryer. If registers or louvers are installed over the openings, then the area must be increased. It
is not
necessary to have separate make-up air openings for each dryer. Common make-up air openings are acceptable.
However, they must be set up in such a manner that the make-up air is distributed equally to the dryers. The
dryer must be installed with provisions for adequate combustion and make-up air supply.
EXAMPLE: For a bank of eight (8) dryers, two (2) unrestricted openings measuring 2 feet by 2 feet
(0.61 meters by 0.61 meters) are acceptable.
IMPORTANT: Make-up air openings should not be located in an area directly near where exhaust
vents exit the building.
Allowances must be made for remote or constricting passageways or where dryers are located at excessive
altitudes or predominantly low pressure areas.
IMPORTANT: Make-up air must be provided from a source free of dry cleaning solvent fumes.
Make-up air that is contaminated by dry cleaning solvent fumes will result in
irreparable damage to the motors and other dryer components.
NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.
