OPTIONS/ACCSSORIS Airflow 2 6 4 2 4 Removable Screen Standard component of wall box and motor side guard. Screen is available with bolted removable or hinged construction. Allows for access to motor, bearings and drive components. Wall Box is used to mount the fan and accessories cleanly into a wall, and provides the strongest and safest way to mount wall fans. Wall boxes are constructed of 6-gauge galvanized steel and are provided with heavy-gauge mounting flanges with prepunched mounting holes for ease of installation. Available fully assembled or as a kit (field assembly required) to reduce shipping costs. Wall supports are provided by others. xtended Lube Lines with grease fittings are extended to the outside of the fan housing. Birdscreen protects the fan's internal components from entry of birds. 6 Filter Box For applications requiring filtered air, filter boxes are available with wall box or wall collar and fan in supply configuration. Filter box contains 2" thick aluminum washable filters and access panels as standard. Disposable filters and " options are also available upon request. Contact factory for more information. Weatherhood keeps snow and rain from entering the building and to prevent wind from altering the performance of the fan and backdraft damper. The weatherhood is designed to fit over the backdraft damper and can be installed to a wall collar via the mounting flanges and prepunched mounting holes. Weatherhoods are constructed of G90 galvanized steel and are standard with a removable galvanized steel, wire mesh, bird screen. Available fully assembled or as a kit (field assembly required) to reduce shipping costs. Weatherhoods are not weather tight when used with supply fans. Twin City Fan 6 TWIN CITY - CATALOG 48
OPTIONS/ACCSSORIS Airflow 2 4 6 2 4 OSHA Motor Side Guard with Removable Screen meets OSHA standards by completely enclosing the motor and drive components. Motor side guards are constructed of galvanized steel side sheets and a removable wire mesh screen. Prepunched mounting holes allow for easy installation to the fan. Can be used with or without a wall collar. NMA 4 Disconnect Switch provides positive electrical shutoff when fan cleaning or maintenance of fan and is water and dust tight. Switch is available shipped loose for field mounting and wiring or factory mounted and wired. See page 8 for other available disconnect switches. Single Point Wiring Available with factory assembled motor side guard or wall box, wired disconnect switch and motorized backdraft damper. Single point wiring option provides a single location for making connections to the damper actuator and disconnect switch. Wall Collars are an economical alternative to the wall box. Wall collars are constructed of 6-gauge galvanized steel. Heavy-gauge mounting flanges with prepunched mounting holes are provided for ease of installation. Available fully assembled or as a kit (field assembly required) to reduce shipping costs. If motor side of fan is to be enclosed, add OSHA motor side guard. Wall supports by others. 6 Backdraft Dampers are used to keep the elements and unwanted air out of the building when the fan is not in use. They are constructed to easily fasten to the wall box or wall collar so that the weatherhood or damper guard can easily fit over it. The standard damper frame is constructed of.062 extruded aluminum and the blades are constructed of 26-gauge mill finished aluminum. The leading edge of each damper blade is flanged with a vinyl seal for effective weather protection and quiet closing. Heavy duty/high velocity dampers are provided when the fan is selected at higher air volumes (see velocity table on page ). Frame and blades are.080 extruded aluminum. The blades freely pivot open or close on stainless steel pivot pins on both types. Motorized options are available. See page for additional information on backdraft damper limits. Damper Guard protects the backdraft damper when a weatherhood is not used. It is constructed of 8-gauge G90 galvanized steel side sheets and a galvanized steel screen. The screening complies with OSHA standards and will keep birds out of the fan and building. Mounting flanges and prepunched mounting holes are provided for ease of installation. 7
DISCONNCT SWITCHS Disconnect switches provide positive electrical shutoff during fan cleaning or maintenance. NMA Disconnect Switch (Standard) A NMA disconnect switch is available shipped loose for field mounting and wiring or factory mounted and wired with ODP or TFC motors. NMA Disconnect Switch NMA R Disconnect Switch A NMA R, rain proof, disconnect is available shipped loose for field mounting and wiring or factory mounted and wired externally. NMA 4 Disconnect Switch A NMA 4, water and dust tight, disconnect is available shipped loose for field mounting and wiring or factory mounted and wired externally. NMA R Disconnect Switch NMA 7/9 Disconnect Switch A NMA 7/9 disconnect switch is recommended on fans with explosion proof motors. The NMA 7/9 switch is designed for use with fans operating in hazardous environments. Available shipped loose for field mounting and wiring. (Not shown.)
