centrifugal type according to UL 705 and fitted with V-belt drive, round hood, and windband
upblast discharge configuration, integral residue trough and collection device, motor and power
transmission components located in outside positively air ventilated compartment.]
10-6.7
In-line fans. Fans shall have centrifugal, backward inclined blades, stationary
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 exhaust fans. Suspended cabinet-type ceiling exhaust fans shall be
centrifugal type, direct-driven. Fans shall have acoustically insulated housing. Integral
backdraft damper shall be chatter-proof. The integral face grille shall be of egg-crate design or
louver design. Fan motors shall be mounted on vibration isolators. Unit shall be provided with
mounting flange for hanging unit from above. Fans shall be U.L. listed.
10-6.9
Range hoods. Kitchen range exhaust fans shall be two-speed, and shall be sized for
an exhaust rate of 7.6 (L/s)/m2 [1.5 cfm/ ft2 ]. Maximum allowable noise level shall be 6 sones
as installed.
10-6.10
Dryer Vents. A 100 mm [4-inch] diameter dryer vent shall individually and directly
discharge to the exterior. The vents shall be rigid aluminum with exterior wall cap and backdraft
damper. Vent pipes shall be a maximum of 6100 mm [20 ft] long, with no more than three right
angle elbows (with minimum radius of 150 mm [6 inches]), and have a maximum vertical run of
3660 mm [12 ft]. Means shall be provided for cleaning entire length of dryer vents. Dryer vents
shall not exhaust near air conditioning condensing units, entry doors, patio or balconies. Dryer
vents shall not run through non-accessible spaces.
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
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 [2] inch 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
SOW-135
