Fan wheels are designed to
provide low operating costs
The forward-curved, centrifugal,
double-inlet fans are statically and
dynamically balanced at the factory to
minimize transmission of vibration
to the building structure.
In addition, the blower is isolated
from the cabinet by rubber isolators,
and the blower is isolated from the duct
connections by foam.
All motors (single and three phase)
are UL (Underwriters Laboratories) list-
ed or equivalent, factory wired, single
speed with thermal overload protec-
tion and are continuous duty rated.
Motors are supplied with permanently
lubricated bearings, class-B insulation
and are open drip-proof. The motor
mount has an adjustable platform for
easy belt adjustment. The motor is re-
silient mounted (up to 2 hp) or rigid
base mounted (3 to 5 hp) for vibration
free installation. Drives are pre-set at
the factory for the specific airflow at
static pressures as ordered. An adjust-
able pitch pulley allows cfm balancing
to meet system requirements.
Complete factory assembly
minimizes on-the-jobsite costs
and problems
Compact, lightweight units are designed
for easy mounting. For horizontal units,
knockouts designed to accept
3
/
8
-in.
threaded rods are provided on the top
and bottom of each corner of the unit.
External vibration isolation and flex
connections for ducts is recommended.
One-in. duct collars on discharge and
on return are furnished standard. These
integral duct collars cut installation time
and labor expense.
Durable construction means
easy-to-maintain units
The 42BHE,BVE fan coil casings are
fabricated from heavy-gage galvanized
G90 steel, reinforced for maximum
rigidity and structural strength. Option-
al one-inch double wall construction,
perforated or solid lined, is also avail-
able. Removable side panels with tool-
less camlock fasteners allow easy ac-
cess for servicing interior components.
One-inch matte surface, fiberglass
thermal/acoustical insulation lines the
fan coil cabinets to prevent sweating
and to muffle sound transmission. Pre-
mium anti-microbial fiberglass, foil
faced, and closed cell insulations are
also available to address IAQ (indoor
air quality) concerns.
The stainless steel, double-sloped
condensate drain pan is removable for
ease of cleaning, and all models in-
clude primary and secondary drain
connections to provide back up in case
the main connection is plugged.
Slide-in return-duct collar filter
makes it possible to remove and re-
place the filter without disturbing
return air ductwork. A standard 2 in.
and optional 4 in. filter rack allow dif-
ferent filter types, thickness, and effi-
ciency to address IAQ requirements.
