Enervex, Inc. Supply-Air Fan SFTA 18

The SFTA supply fan is used to supply combustion air/make-up air to mechanical rooms and laundry facilities. In supply applications it is installed inline where it ca maintain a constant pressure in the entire duct system. For optimal performance the fan speed can be controlled by a modulating pressure control (EBC 30, EBC 35 or EBC 14). In supply applications, it is installed at the air intake where it is controlled by an EBC 30 Modulating Pressure Control. The supply fan is typically used in applications where a louver can't be used for practical or aesthetical reasons.
