discharge conversion vanes, internal and external belt guards, and adjustable motor mounts.
Fans shall be mounted in a welded tubular casing. Air shall enter and leave the fan axially.
Inlets shall be streamlined with conversion vanes to eliminate turbulence and provide smooth
discharge air flow. Fan bearings and drive shafts shall be enclosed and isolated from the air
stream. Fan bearings shall be sealed against dust and dirt and shall be permanently lubricated,
and shall be precision self aligning ball or roller type. Fans shall be tested and rated according
to AMCA 210.
10-6.8
Ceiling destratification fans. [Fans shall be mounted in high bays and shall be
[propeller] [centrifugal] type. Fans shall be controlled by [thermostat ] [wall switch].]
10-7
AIR DISTRIBUTION CENTRAL EQUIPMENT. Minimum equipment efficiencies shall
be in accordance with DOE Buying Energy Efficient Products Recommendations (refer to
10-7.1
Indoor air handling units. Units shall include fans, coils, airtight insulated casing,
adjustable V-belt drives, belt guards for externally mounted motors, access sections for
maintenance, combination sectional filter-mixing box, vibration-isolators, and appurtenances
required for required operation. Air handling unit shall have published ratings based on tests
performed according to ARI 430. All sections shall be constructed of a minimum 18 gauge
galvanized steel, or 18 gauge steel outer casing protected with a corrosion resistant paint finish.
Casing shall be designed and constructed with an integral structural steel frame such that
exterior panels are non-load bearing. Casings shall be provided with inspection doors, access
sections, and access doors. Inspection and access doors shall be insulated, fully gasketed,
double-wall type, of a minimum 18 gauge outer and 20 gauge inner panels. Drain pans shall be
constructed water tight, treated to prevent corrosion, and designed for positive condensate
drainage. Coils shall be fin-and-tube type constructed of seamless [copper] [red brass] tubes
and [aluminum] [or] [copper] fins mechanically bonded or soldered to the tubes. Coils shall be
rated and certified according to ARI 410. Filters shall be listed according to requirements of UL
900. Filters shall be 50 mm depth, sectional, disposable type of the size indicated and shall
have an average efficiency of 25 to 30 percent when tested according to ASHRAE 52.1. Filters
shall be UL Class 2. Fans shall be double-inlet, centrifugal type with each fan in a separate
scroll. Fan bearings shall be sealed against dust and dirt and shall be precision self-aligning ball
or roller type. Bearing life shall be L50 rated at not less than 200,000 hours as defined by
AFBMA Std 9 and AFBMA Std 11. Bearings shall be permanently lubricated or lubricated type
with lubrication fittings readily accessible at the drive side of the unit.
10-7.2
Rooftop packaged air handling units. Units shall be same as indoor air handling units
except casing and intakes shall be weatherproof and roof curbs shall be supplied with the unit.
10-7.3
Heating and ventilating units. Units shall be same as indoor air handling units.
10-7.4
Warm air furnaces. Furnace shall be a manufacturer's standard, self-contained,
forced circulated air heating type furnace. Furnace and furnace components shall be
completely factory-assembled and wired. Furnace casing shall be factory insulated and be
compatible with the operating temperatures. Furnace shall be provided with removable service
panels which allow access to all internal components requiring cleaning, servicing, or
adjustment.
10-7.4.1 Gas-fired furnace. Shall be the high efficiency, condensing type in accordance with
ANSI Z21.47. Furnace design shall be certified by the American Gas Association Laboratories
SOW-92
