BCRD-E Endurex Roof Exhausters, Belt Driven Model BCRD-E belt driven roof exhausters feature a housing constructed of Twin City Fan & Blower's proprietary Endurex polymeric material. The polymeric construction of Endurex provides the same long lasting characteristics as aluminum but with significantly improved impact, weather, corrosion, and UV resistance. To prove our confidence in Endurex we are providing a limited lifetime warranty on all Endurex housing components. Standard Models Available in ten sizes from 070 through 240 Capacities range from 80 to 8,700 CFM, with static pressures to 2.25 inches High-Pressure Models Available in six sizes from 00 through 240 Capacities range from 330 to 7,700 CFM, with static pressures to 3.25 inches Endurex Construction Advantages Impact Resistant - Housing will not dent or crack even in cold weather to -40 o F. Weather Resistant - Resistant to storm damage caused by wind, hail and airborne objects. Corrosion Resistant - Impervious to salt, airborne chemicals and normal weathering. UV Resistant - UV inhibitors provide resistance to ultraviolet light for long years of service. Resists Shipping Damage - Impossible to dent and alter housing shape caused by improper handling. Safe Installation - Provides safe areas to grab for installation and maintenance without sharp metal edges. Ease of Maintenance - Removable top cover provides for belt inspection and maintenance, while the onepiece construction provides easy removal and access to the wheel. C E SQUARE A DIA.

The Endurex material underwent rigid testing per these standards, surpassing the requirements of the following: Ultraviolet Light Exposure Testing Samples were exposed to ultra violet light for an equivalent of 500,000 hours (90+ years) to provide the assurance that the material will last a lifetime. Flammability Testing Flame tests performed per UL94, the most widely accepted flammability performance standards for plastic materials, gauged the material s ability to propagate or extinguish a flame once ignited. Impact Resistance Testing Tensile and izod impact tests measured the material s resistance to real life conditions such as, falling objects, blows, collisions, drops, etc. Functional Support Testing Flexural and tensile strength tests to prove the material s structural stability and integrity.

Construction Features Wheel Quiet and efficient non-overloading wheels with backwardly curved blades are precisely matched to a deep spun venturi. All wheels are statically and dynamically balanced to ensure smooth and quiet operation. Housing BCRD-E housings feature Endurex polymeric construction of the housing and top cover. Twin City Fan & Blower's proprietary Endurex material provides significantly improved impact, weather, corrosion and UV resistance. BCRD housings feature heavy gauge spun aluminum construction of the shroud and top cover. Shrouds feature a rolled bead edge for rigidity. Motor bands are constructed of heavy gauge aluminum, rolled and beaded for rigidity. DCRD housings feature heavy gauge spun aluminum construction of the shroud and top cover. Shrouds feature a rolled bead edge for rigidity. All housings provide complete protection of the motor and drive assembly, while allowing quick access to these components. Curb Cap One-piece curb cap/inlet venturi assembly features welded corners to provide complete protection from weather. Prepunched mounting holes provide easy and accurate attachment to the roof curb. Shaft Precision ground and polished with a first critical speed of at least 25% of the fan s maximum operating speed. Bearings Heavy-duty re-greaseable pillow block ball bearings are specifically designed for air handling applications to provide an average life (L-50) of 500,000 hours or more at maximum cataloged operating speeds. Vibration Isolation Wheel, motor and drive assembly are completely isolated from the fan supports by rubber isolators to reduce transmission of noise and vibration. Motors ODP, TEFC, and explosion proof, single and three phase motors are carefully matched to the fan load. Drive Adjustable pitch V-belt drives with cast iron sheaves and heat resistant belts are selected at 50% of the driven motor horsepower. Balancing Entire fan assembly is balanced and tested at the factory before shipping. Galvanized Bird Screen Protects the wheel, inlet, and internal components from entry of birds. Disconnect Switch Standard on all units. Fans are provided with a NEMA- type disconnect switch mounted in the motor compartment when ODP or TEFC motors are used. When explosion proof motors are specified, a NEMA- 7/9 disconnect switch will be shipped loose for field mounting and wiring. Conduit Tubing A conduit tube is furnished for running electrical wiring through the curb cap and into the motor compartment. Conduit tubes are constructed of Electrical Metallic Tubing (EMT). A conduit embossment and watertight fitting on the curb cap prevents the entrance of water into the ductwork. Nameplate Permanently attached nameplate displays serial number and unit information for future identification. 6 Twin City Bulletin 4050

Accessories Backdraft Damper Backdraft dampers, with automatic or motorized operation, feature a felt seal on the edge of the damper blades for quiet operation. Damper frames are constructed of 20-gauge galvanized steel and blades are constructed of 26-gauge aluminum. Motorized dampers are recommended for low CFM applications to assure unrestricted airflow. Motorized dampers are available with 5, 208, 230, 460 or 575 volt service; 575 volt service requires a step-down transformer. When a motorized damper option is selected a 2" (or greater) high roof curb is required. Curb Hinge The curb hinge arrangement provides easy access to the exhaust fan, backdraft damper and duct for servicing and cleaning. The curb hinge is of the piano type, running the entire length of the fan's curb base. The curb hinge option ships loose and is designed for use with a standard canted curb only (.5" less than fan base). This option cannot be used with self-flashing curbs. Retaining Chain A retaining chain is available in conjunction with the curb hinge arrangement to stabilize the unit and to prevent damage from occurring to the unit while servicing and cleaning. Security Hasp A security hasp is available in conjunction with the curb hinge arrangement to prevent removal of the unit from the unit curb cap and prevent entrance into the building through the roof s ductwork. Prefabricated Roof Curbs Prefabricated roof curbs are available in heavy duty galvanized steel or aluminum construction, in heights of 8", 2", or 8". The standard curb (canted) is provided with a factory installed wood nailer, while the optional self flashing design is provided with a /4" polystyrene gasket. Both the standard curb and the self flashing design are provided with.5" of insulation as standard and feature continuously welded seams for added rigidity and moisture protection. Prefabricated curbs are also available in raised cant, pitched and peak models. Refer to Bulletin 490 for complete details on roof curb options. Aluminum Insect Screen Provides protection from entry of insects into wheel, inlet and interior of building. Variable Speed Control Variable speed control is an optional accessory on all DCRD models. To allow the adjustment of airflow for system balancing. Variable speed controllers are solidstate (Tri-ac) design, and are designed to start the motor on high speed for better startup characteristics. Variable speed controls can be shipped separately, factory installed, or field installed on the unit at a later date. Motor must be ODP 5V, PSC or shaded pole type. NEMA-4 Disconnect Switches A NEMA-4, water and dust tight disconnect is available shipped loose for field mounting and wiring. 2-Speed Switch Two speed switch is available for 2 speed/2 winding motors to control the fan speed (high speed, low speed, off). Available on single phase, and below. Firestat The firestat option is intended to shut down the unit in case of a fire in the building. If the firestat sensing element is exposed to an air temperature over its set point, it will open, de-energizing the motor of the unit. The standard firestat is set to open at 40ºF and must be manually reset. The firestat cut-out point is field adjustable from 00ºF to 70ºF. Firestats are available for 5, 208, 230 and 277 volt, -phase units, either factory or field installed. Special Coatings Powered roof exhausters often require special coatings for protective and decorative purposes. Available coatings include air-dried enamel, air-dried epoxy, and Heresite (air-dried phenolic). Contact your Twin City Fan & Blower representative for more information on available coatings and colors. Minimum 2" high curbs are recommended for use with motorized damper. 8 Twin City Bulletin 4050
