The fan packages shall be factory assembled complete with electric heat/hot water coils. Factory mounted
control panel shall provide all internal control and fan power wiring for a single point field connection. An
optional factory mounted disconnect switch shall be furnished and prewired so as to disconnect all electrical
components in the fan package. A single point field connection will be made at the disconnect switch. Fan
package must be labeled and listed by a nationally recognized and locally accepted testing laboratory, such
as ITS Intertek testing services. Fan packages must be tested for safety and in accordance with the latest
National Electric Code. Casing shall be a minimum of 20 gauge galvanized steel and acoustically insulated
with 1” fiberglass. The casing shall be Listed and meet NFPA and NBFU 90A requirements. Blower casing
shall be constructed of heavy gauge steel and baked enamel finish. Fan wheel shall be forward curved
centrifugal type, dynamically balanced and be driven by direct drive, single speed permanent split capacitor
motors. Motors shall be single phase, 1050 RPM. An electronic motor speed control shall be provided to
allow continuously adjustable fan speed from minimum to maximum and shall incorporate a minimum
voltage stop to insure motor cannot operate in stall mode. Fan assembly shall be mounted on a 16 gauge
steel sub-base, but shall be internally isolated with rubber-in-shear isolators to prevent vibration transfer to
the sub-base. Motors shall also be isolated with rubber-in-shear isolators between the motor mounting legs
and the blower casing. Fan motor assembly shall be accessible through access panels from both sides and
rear of cabinet (bottom and top access panels are not acceptable). Access panels shall have gasket to prevent
leakage and vibration transmission. An electric heater (hot water optional) shall be part of the total listed
package and shall be controlled by pneumatic, electric controls enclosed in a NEMA-1 enclosure on the side
of the cabinet. The panel shall be gasket sealed to prevent air leakage. Heater shall be the requested available
voltage and phase. Each fan package will be factory tested prior to shipment and certified as such. Each fan
shall have an optional throw-away or permanent filter, and an optional acoustically lined discharge plenum
or return air boot.
