Turning Air Into Solutions. BACKWARD CURVED HIGH PRESSURE FANS MODEL BCS CATALOG 400 November 2013 CentrifugalFans Model BCS Backward Curved - High Pressure The BCS fan from Twin City Fan & Blower is a high efficiency backward curved industrial fan designed for handling relatively clean air in high pressure applications. Typical applications include combustion air, product cooling, moisture blow-off, forced draft on fluid bed boilers, and induced draft after baghouse process blowers. Because the BCS features a wider wheel and housing, producing a high volume of air at a lower velocity, the need for an expansion evasé is eliminated. BCS fans are available with a variety of construction options and accessories, offering the versatility and flexibility required in today's industrial applications. Sizes Arrangement 9F 16.5" to 89" wheel diameters Performance Airflow to 422,500 CFM at 2" w.g. Static pressure to 40" w.g.

The high efficiency wheel features backward curved blades of single thickness, continuously welded to the rim and backplate. A conical spun shroud (rim) makes BCS fans less susceptible to the performance losses associated with poor inlet conditions. All BCS wheels are statically and dynamically balanced to grade G6.3 per ANSI S2.19 for smooth operation prior to assembly of the fan, followed by a final balance of the entire rotating assembly. Shaft Shafts are AISI-1018, 1040 or 1045 hot-rolled steel accurately turned, ground, polished, and ring gauged for accuracy. Shafts are generously sized for first critical speed of at least 1.43 times the maximum speed for the class. BCS Wheel Bearings Bearings are heavy-duty, grease-lubricated, anti-friction ball or roller, self-aligning, pillow block type and are selected for minimum average bearing life (AFBMA L-50) in excess of 200,000 hours at the maximum fan RPM. Rotation and Discharge Both clockwise and counterclockwise rotations are available in various standard discharge positions. See drawings on pages 28-41. Temperature Limits Standard construction designed for temperatures up to 300°F. Optional construction available to handle up to 800°F. See page 7. Outlet Flange Punched outlet flange is provided as standard construction on all sizes. Arrangement 1 Mechanical Run Test & Final Vibration Check All fans are assembled for a mechanical run test as well as final balance prior to shipment. Vibration readings are taken on both fan bearings in the axial, horizontal, and vertical directions at the specified speed. Fans are balanced to 0.15 in/sec. peak or less. Special Materials BCS fans can be constructed of special materials such as aluminum and stainless steel. www.tcf.com 3 OptionalConstruction Spark Resistant Construction Fan applications may involve the handling of potentially explosive or flammable particles, fumes or vapors. Such applications require careful consideration by the system designer to insure the safe handling of such gases. Twin City Fan & Blower offers the following classifications of spark resistant construction per AMCA Standard 99-0401-86. It is the specifier’s or the user’s responsibility to specify the type of spark resistant construction with full recognition of the potential hazards and the degree of protection required. Type A:All parts of the fan in contact with the air or gas being handled shall be made of nonferrous material — usually aluminum and limited to 250°F. Type B:The fan shall have a nonferrous impeller and nonferrous ring about ing through which the shaft passes aluminum wheel and rub ring and 250°F. Fan with Split Housing Split Housing A flanged horizontal split housing is available on the fan’s centerline. A pie-shaped split is also available for wheel removal without disturbing the ductwork. High Temperature Construction Airstream temperatures above 300°F require high temperature construction. See page 7 for construction requirements. Insulation pins and complete fan insulation are available. InletBoxes To Suit Fan D C Type C:The fan shall be so constructed that a shift of the wheel or impeller or shaft will not permit two ferrous parts of the fan to rub or strike. This is accomplished with an aluminum inlet cone and rub ring. This construction is limited to 500°F. Construction to 800°F is available using a steel inlet cone with copper/bronze lining. Notes: 1.Bearings shall be placed outside the airstream. Therefore, do not use Arrangement 3 or 7. 2.The user shall electrically ground all fan parts.

Contact factory in these cases. Performance Correction For Temperature & Altitude The performance tables in this catalog are based on fans handling standard air at a density of 0.075 pounds per cubic foot. This is equivalent to air at 70°F at sea level (29.92 Hg barometric pressure). Thus, when specified performance is at a density different than standard, it must be converted to the equivalent standard conditions before entering the performance tables. The equivalent standard conditions can be calculated by using the Temperature and Altitude Density Ratios shown below.

'FR' equals maximum motor frame. www.tcf.com 41 TypicalSpecifications Fans shall be Model BCS, Backward Curved High Pressure Blowers, as manufactured by Twin City Fan & Blower, Minneapolis, Minnesota. PERFORMANCE — Fans shall be tested in accordance with ANSI/AMCA Standard 210 (air performance) and 300 (sound performance) in an AMCA accredited laboratory. Fans shall have a sharply rising pressure characteristic extending through the operating range and continuing to rise beyond the peak efficiency to ensure quiet and stable operation. Fans shall have a non-overloading design with self-limiting horsepower characteristics and shall reach a peak in the normal selection area. CONSTRUCTION — Fan housings and bearing pedestals shall be of heavy-gauge, continuously welded construction. Housings with partially welded construction are not acceptable. Housings shall be suitably braced to prevent vibration or pulsation. Discharge flanges shall be provided for rigidity and duct connection. Discharge flanges are punched as standard. All units are furnished with lifting lugs. WHEEL — BCS backward curved wheels shall be single thickness, designed for maximum efficiency and quiet operation, and shall be continuously welded to the rim and back plate. Partial welding is not acceptable on backward curved blades. All wheels shall be statically and dynamically balanced. SHAFT — Shafts shall be AISI 1018, 1040 or 1045 hot rolled steel, accurately turned, ground, polished, and ring gauged for accuracy. Shafts shall be sized for the first critical speed of at least 1.43 times the maximum speed. BEARINGS — Bearings shall be heavy duty, grease lubricated, anti-friction ball or roller, self-aligning, pillow block type and selected for a minimum average bearing life (AFBMA L-50) in excess of 200,000 hours at the maximum fan RPM. DRIVE — Motor sheaves shall be cast iron, variable pitch on applications 20 HP and smaller, and fixed pitch on 25 HP and larger. Drives and belts shall be located external to the fan casing and rated for 150% of the required motor HP. FINISH AND COATING — The entire fan assembly, excluding the shaft, shall be thoroughly degreased and deburred before application of a rust-preventative primer. After the fan is completely assembled, a finish coat of paint shall be applied to the entire assembly. The fan shaft shall be coated with a petroleum-based rust protectant. Aluminum components shall be unpainted. ACCESSORIES — When specified, accessories such as access doors, drains, inlet and outlet flanges, belt guards, shaft and bearing guards, outlet screens, outlet dampers, inlet vanes, spark resistant construction, split housings, high temperature construction, shaft seals, inlet boxes, and shaft coolers shall be provided by Twin City Fan & Blower to maintain one-source responsibility. FACTORY RUN TEST — All fans prior to shipment shall be completely assembled and test run as a unit at the specified operating speed or maximum RPM allowed for the particular construction type. Each wheel shall be statically and dynamically balanced in accordance with ANSI/AMCA 204-96 “Balance Quality and Vibration Levels for Fans” to Fan Application Category BV-3, Balance Quality Grade G6.3. Balance readings shall be taken by electronic type equipment in the axial, vertical, and horizontal directions on each of the bearings. Records shall be maintained and a written copy shall be available upon request. GUARANTEE — The manufacturer shall guarantee the workmanship and materials for at least one (1) year from startup or eighteen (18) months from shipment, whichever occurs first. 42 Twin City Fan Catalog 400 • • • • • • AlternativeCentrifugalFans BCSF — Backward Curved High Pressure Composite Fans 16.5" to 60" wheel diameters Airflow to 151,000 CFM Static pressure to 34" w.g.
