   ACCESSORIES   
 
 
Discharge damper, two-position motor and interlock:
motor-operated parallel blade damper that prevents warm air from escaping the building through the unit. The motor-damper end switch energizes the starter circuit when the damper is in the full-open position, and returns to a closed position during shutdown. Down discharge arrangement units available with our exclusive "Hassle Free Damper" internally mounted in unit.
 
Discharge louvers with air diffuser:
discharges air in four directions with vertical and horizontal blades, and is field-installed. The blades can be manually adjusted to set direction of airflow.
 
Filter section:
removable, hinged access door, with a 2-inch washable, aluminum-mesh filter, or a 2-inch pleated filter. Also available with 1-inch, 1.5 lb density insulation.
 
Fresh-air intake hood with birdscreen:
prevents rain or snow from entering the unit with a 1-inch mesh screen on hood face; sized to fit unit's fresh-air intake. Shipped loose to be field installed.
 
Full-downturn inlet hood:
prevents rain and snow from entering the unit by bringing air into the bottom of the hood with a 1-inch wire-mesh screen, and is field installed. Large hoods are shipped separately, and must be field assembled.
 
Inlet-hood filters, 2-inch:
cleanable, aluminum-mesh filters mounted on the inlet-hood face in lieu of a separate filter section. Not available on RAM-M 227 and larger models.
 
Inlet screen:
prevents material from entering unit. A 1-inch mesh screen fastens to unit's fresh-air intake.
 
Inlet damper, two-position motor and interlock:
motor-operated parallel blade damper that prevents outside air from entering the building through the unit. The motor damper end switch energizes the starter circuit when the damper is in the full-open position, and returns to a closed position during shutdown.
 
Return-air filter, 80/20 units:
2-inch deep, aluminum mesh, or 2-inch deep, 30% efficient, pleated type; v-bank, filter section shipped loose for field mounting to the return-air connection.
 
Standard curb:
24-inch roof curb formed of 12-gauge steel; 14-inch curb is also available. Shipped separately, and must be field assembled. Insulation, cant, and wood nailer by others
 
 
 
 
   OPTIONS   
 
 
Adjustable drives:
fixed-pitched sheaves are standard on motors 25 HP and larger. An adjustable-pitch motor sheave is provided in lieu of the standard fixed-pitch sheave.
 
Casing insulation:
adds 1", 1.5 lb density insulation to inner surface of unit's walls and ceiling, casing liners are standard with this option.
 
Casing liners with insulation:
prevents insulation fibers from being drawn into air stream and discharged into conditioned space, and prevents physical abuse and moisture damage to insulation. Made of galvanized steel.
 
Extended grease lines:
lubrication lines from blower bearings to a common point on the unit's exterior. Units with permanently lubricated bearings to be changed to pillow block-type.
 
Floor-mounted spring isolators:
box-type lifting points replace standard lifting eyes; 1-inch deflection spring mounts shipped loose for field installation.
 
Hanging spring isolators, 1-inch:
shipped loose for field installation.
 
Painted casings:
one coat of beige air-dried enamel over a vinyl wash primer.
 
Pillow-block bearings, 100,000 hr:
standard on all units ordered with an industrial blower, and are rated at 100,000 to 200,000 hours; available on smaller units with standard, permanently lubricated ball bearings.
 
Spring-isolated blower and motor:
mounted on a 1" deflection spring isolated base. A flexible duct connects the fan outlet to the unit's casing.
 
Two-speed damper package:
provides burner-profile dampers that automatically maintain the correct burner velocity. Also dual airflow switches and rate-limiting control are included to prevent over-firing on low speed.
