Featuring a compact, rectangular cabinet design, model BCF mounts easily in standard duct passages. Horizontal mounting with either top horizontal or upblast discharge allows the BCF to be applied in a wide range of air handling applications. BCF cabinet fans are available in single and double fan models. Both feature the combination of a quiet running, forward curved wheel and a well proportioned fan housing for efficiency. In double fan models, each wheel is housed separately, but both are driven by a single motor and shaft. wheels are statically and dynamically balanced to assure vibration free operation. Every model has been designed with low-profile construction to fit within tight spaces, as low as inches (280 mm). Capacities range from 70 to 5,850 cfm (290 to 9950 m 3 /hr) with static pressures up to ½ in. wg (375 Pa). All fan sizes are tested in our AMCA Accredited Laboratory, and all BCF sizes are licensed to bear the AMCA Certified Ratings Seal for Air Performance. Greenheck subjects these products to extensive life testing assuring you that the fans will provide years of reliable performance. Greenheck Corporation certifies that the model BCF fans shown herein are licensed to bear the AMCA Seal. The ratings shown are based on tests and procedures performed in accordance with AMCA Publication 2 and comply with the requirements of the AMCA Certified Ratings Program. The certified ratings for model BCF are shown on pages to 5. Enjoy Greenheck s extraordinary service, before, during and after the sale.

3 Standard Construction Features Vibration Isolation - Internal true vibration isolators support the entire drive assembly, wheel, and scroll without steel to steel contact. This provides long life and quiet operation. Housing - The fan cabinet is constructed of galvanized steel for corrosion resistance and maintenance free operation. Access Panel - Hinged or removable panels allow for easy access to all internal components. Hinged panels are on fan sizes 0, 07, 20 and 207 and are removable on the larger sizes in both single and double fans. Bearings - Permanently sealed, pillow block ball bearings are selected for a minimum L 0 life in excess of 00,000 hours (L 50 average life of 500,000 hours) at maximum catalogued operating conditions. Wheel - Forward curved, centrifugal, galvanized steel wheel is utilized to generate high efficiency and minimal sound. Each wheel is statically and dynamically balanced for long life and quiet operation. Housing Motor - Ball bearing motors are carefully matched to the fan load. Open drip proof and totally enclosed enclosures are available. Drive Frame - Constructed from heavy gauge steel and designed with belt adjustment to eliminate scroll damage. Adjustment is accomplished by loosening fasteners, sliding the motor plate, and retightening. Drive Assembly - Belts, pulleys and keys are sized for a minimum of 50% of driven horsepower. Machined cast iron pulleys are factory set to the required RPM and adjustable for final system balancing. Belts are static free and oil resistant. Shaft - Precisely sized, ground, and polished so the first critical speed is at least 25% over the maximum operating speed. Close tolerances between the shaft and bearing result in longer bearing life. Duct Collars - Inlet and outlet duct collars are provided for easy duct connections.

4 Options and Accessories Mixing Boxes - Constructed of galvanized steel and available with or without dampers. Inlet position must be specified. Any two of the three positions shown (X, Y or Z) may be selected. Filter Boxes - Constructed of galvanized steel. Available with either a sloped filter arrangement or vertical slide-out. Smaller fan sizes (0, 07, 20 and 207) have a sloped single angled filter. The doublevee configuration is used with all larger sloped sizes. Filters are available in or 2-inch disposable media or permanent, washable aluminum mesh. Filter boxes with slide-out have 2-inch washable aluminum filters. Sloped, Single Angled Filter - Sizes 0, 07, 20 and 207 Y X Z Side Access Doors - For installations where normal access is restricted, removable side access doors are available for ease of inspecting and servicing fan wheels, motors, belts and drives. Door locations must be specified left or right as viewed from the discharge end of the fan. Surrounding ductwork or other equipment should be considered when selecting the access door location. Insulated Housing - For noise reduction and condensation control, the interior of fan housings, mixing box and filter box can be lined with a inch fiberglass duct liner. Disconnect Switches - A wide selection of NEMA rated switches are available for positive electrical shutoff and safety. This includes general, dust-tight, rainproof, and corrosion-resistant. Vibration Isolators - Base and hanging isolator kits are available with either neoprene or spring isolators. Kits range in size to support either the weight of the fan alone or the weight of the fan with filter and mixing box combinations. Kits are for horizontal mounting and include mounting brackets and hardware. Knockouts are provided in the fan cabinet for ease of installation. (Hanging rods supplied by others.) Sloped, Double-Vee Filter - Sizes 08, 0, 2, 208, 20 and 22 Hanging Spring Neoprene Standing Spring Hanging Neoprene Slide-Out, Aluminum Filter - Sizes 0 thru 22 Wiring Pigtail - Allows direct hook-up to the power supply externally (eliminating field wiring at the fan). Coatings - A wide variety of protective or decorative coatings are available.

To select the most effective fan position and discharge, it is necessary to consider the direction of air entering the fan and the direction of exhausted air. All of the accessories shown on page four can be used with the installations shown. In order to assure proper fan performance, caution must be exercised in fan placement and connection. Obstructions, transitions, poorly designed elbows, etc., can cause reduced performance, excessive noise, and increase mechanical stress. For performance to be as published, the system must provide uniform and stable airflow into the fan.

Provide uniform airflow to the fan inlet. Use turning vanes in elbows to reduce adverse effects where needed. Do not install fans with ductwork directing airflow in the opposite direction of wheel rotations. Avoid sharp turns, poorly designed elbows, and transitions which cause uneven airflow. 5
