NOTES:
Constant speed units are rated at capacities shown in regular type; capacities shown in italic faced type apply only to units with multi-speed motors.
** Performance data based on 2 lbs. steam pressure at heater with air entering @60°F.
To determine BTU per hour capacities at various steam pressures and entering air temperatures, use conversion factors from
be calculated by applying basic formula.
