2 Direct DrivePanel ans Model panel fans are direct drive panel fans designed for low static pressures. They can be mounted in a wall vertically or in a ceiling horizontally. All units come standard with a spun galvanized panel, zinc plated motor mount/guard, custom engineered motor and an aluminum blade that is statically and dynamically balanced. They are manufactured under strict ISO 9001 quality standards and performance is certified by AMCA. Sizes Available in 8 base sizes with blade diameters of 8",10", 12", 14", 16", 18", 20" and 24" Motor and blade pitch combinations make up a total of 31 unique performing model sizes Performance Capacities from 100 to 7600 CM Static pressures to 5 8" w.g. The addition of speed control adds flexibility to the performance capabilities of all sizes Panel an Configurations Exhaust and supply configurations available Construction eatures All spun panels are constructed of 16 gauge G90 galvanized steel The standard motor mount also serves as a motor side guard that complies with OSHA standards All steel guards are zinc plated to inhibit corrosion The motor mount/guard is secured to the fan panel with captivated nut inserts that allow for easy servicing without the removal of the full panel after installation All ODP and TE motors are custom engineered and come in a variety of standard voltages. All single phase 115V ODP motors can be used with a variable speed controller ixed pitch aluminum fan blades Prepunched panel holes for easy mounting Twin City an & Blower certifies that the Model shown herein is licensed to bear the AMCA Seal. The ratings shown are based on tests and procedures performed in accordance with AMCA Publication 211 and AMCA Publication 311 and comply with the requirements of the AMCA Certified Ratings Program. an Efficiency Grade (EG) certification applies to Model, Size 242A. 2 Twin City an Bulletin 4800

3 Electronically Commutated Motors Twin City an is now offering its own line of custom engineered Electronically Commutated (EC) motors. Electronic commutation is the latest motor technology to be used in direct drive fans. Also known in the industry as Brush ree or Brushless DC, the EC motors utilize an electronic circuitboard to control the functionality of the motor. The motor operates off of 115V AC single phase power, which is converted to DC power within the motor s circuitry. The result is a highly efficient motor with an expanded speed control range and a variety of speed control options to choose from. Benefits Efficiencies up to 85% Constant efficiency as the motor speed is varied Up to 66% energy savings over traditional PSC motors Performance range comparable to a belt drive fan with reduced maintenance benefits of a direct drive fan 80% usable turndown range as compared with 40% maximum on PSC motors Soft start gives fans smooth, quiet start Lower operating temperatures result in longer life and reduces energy consumption Heavy duty ball bearings are permanently lubricated Elimination of VD results in lower initial cost ECMotors With EC Motor Speed Control Options Motor Mounted Dial A pontentiometer is mounted to the motor housing offering full speed control range. Speed adjustment is made with a small flat head screwdriver making system balance simple and easy. Also eliminates the need to mount or wire a speed controller. 0-10V DC Lead A 36" long control lead is prewired to the motor which accepts a 0-10V DC signal and can be wired into building control systems. Remote Mounted Dial A wall mounted dial allows the fan to be controlled from within the building by sending the motor a 0-10V DC signal. This option includes a 115V to 24V AC transformer mounted in a NEMA 1 electrical enclosure. Motor Mounted Speed Control Dial Remote Mounted Speed Control Dial 2012 Twin City an Companies, Ltd.

4 O ON ProductAccessories Wall Collar The wall collar is used to mount the fan and accessories cleanly into a wall. The collar will give the fan package a finished look when fully installed. It is constructed of 16 gauge G90 galvanized steel and can be ordered fully assembled or as a kit (field assembly required) to reduce shipping costs. Wall Box The wall box is used to completely enclose the fan and accessories. Constructed of 16 gauge galvanized steel with a removable screen. It is available fully assembled or as a kit. (Wall box not shown below.) Backdraft Damper The backdraft damper is used to help keep the elements and unwanted air out of the building when the fan is not in use. It is constructed to easily fasten to the wall collar or wall box so that the weatherhood or damper guard can easily fit over it. The frame is constructed of 20 gauge galvanized steel and the blades are 26 gauge mill finished aluminum with a vinyl seal along the leading edge for quiet closing and weather protection. An actuator motor is available as an option to allow the damper to be powered. Disconnect Switch A NEMA-1 disconnect switch is available. It is shipped loose from the factory for field installation. Damper Guard Screen The damper guard screen is used to protect the backdraft damper when a weatherhood is not being used. It is constructed of 18 gauge G90 galvanized steel and comes with a galvanized screen. The screening complies with OSHA standards and will keep birds out of the fan and building. Weatherhood with Guard Screen The weatherhood is used to keep the elements from entering the building and to prevent wind from affecting the performance of the fan and backdraft damper. It easily fits over the backdraft damper and can be installed to the wall collar or wall box through the prepunched holes. The weatherhood is constructed of 18 gauge G90 galvanized steel and comes standard with a removable bird screen. It can be ordered fully assembled or as a kit (field assembly required) to reduce shipping costs. Variable Speed Controller Variable speed control is an optional accessory on all models with 115V, ODP PSC type motors. The speed controller is designed to start the motor on high speed for better startup characteristics. Variable speed controllers are shipped loose for field mounting. (It is recommended that the speed controller be placed within 10 feet of the fan for maximum performance. If placing farther away than 10 feet, shielded wire is recommended to reduce electrical noise and interference.)
