4 OFF ON Accessories Wall Box with Guard The 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 16-gauge G90 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 Collar The wall collar is an economical alternative to the wall box. They are constructed of 16-gauge G90 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. Backdraft Damper 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 so they will easily fasten to the wall box or wall collar and so that weatherhood or damper guard can easily fit over it. The frame is constructed of 19-gauge galvanized steel. Damper blades are constructed of 26-gauge mill finished aluminum. The leading edge of each damper blade is flanged with a felt seal for effective weather protection and quiet closing. The blades freely pivot open or close on stainless steel pivot pins. A motorized option is available.

5 OFF ON Accessories Damper Guard The damper guard is used to protect the backdraft damper when a weatherhood is not used. It is constructed of 18- 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. Weatherhood with Bird Screen A weatherhood is available to keep 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. They are constructed of 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. An optional painted coating is available. OSHA Motor Side Guard The motor side guard meets OSHA standards by completely enclosing the motor and drive components. They are constructed of galvanized steel side sheets and a removable wire mesh screen. Prepunched mounting holes allow for easy installation to the fan. (For use with a wall collar.) Disconnect Switch A NEMA 1, 3R or 7/9 safety disconnect switch is available for positive electrical shutoff of the fan and the protection of service personnel. Disconnects are shipped loose for field mounting and wiring.
