4 Wall Collar and Optional Accessories Wall Collar The heavy gauge, galvanized mounting collar provides a simple solution to installing a fan in a rough wall opening when a rear safety guard is NOT required. A front wire guard, shutter, and/or rainhood can be attached to the front pre-punched flanges. The wall collar can be used in exhaust or supply applications for all fan sizes. The wall collar is mounted with the fan on the interior side of the building. All collars ship fully assembled with the fan to lessen job site installation costs. We strongly recommend rainhoods and motorized shutter for all supply applications as well as for exhaust applications where additional weather protection is desired.

Motorside Guard G Sheet Metal and Wire Motorside Guard An assembled heavy gauge galvanized steel housing is available with front or rear OSHA approved flat wire safety guard with q x 1 in. galvanized welded wire. This housing and guard attaches to the fan panel. It ships pre-assembled to lessen installation cost, but is available knockeddown for field assembly. Optional heavy duty OSHA approved guard is constructed of heavy gauge aluminum expanded metal. Please note that this style guard is not compatible with wall collar or wall housing. Adequate clearance must be maintained between fan blade and damper. Flat Guard (Removable) H J 4

5 Wall Housing and Optional Accessories Wall Housing This heavy gauge, all galvanized steel housing provides a simple solution to installing a fan and all required accessories in a rough wall opening. It can be used in exhaust or supply applications and in fan sizes 24 through 72 inches. Depending on space and maintenance requirements, the wall housing may be installed inward or outwards of the building. All housings ship assembled with the fan to lessen job site installation costs. Wire guards, shutters and/or rainhoods may be attached to the prepunched flange. We strongly recommend rainhoods and motorized shutters for all supply applications and whenever additional weather protection is desired.

6 Options: Inlet Guard Outlet guard Rainhood Adjustable speed drives (Standard through 3 HP) Damper Box construction Discharge Shutter Automatic type shown. Eliminates backdraft and rain entry. Motor Side Wire Guard Galvanized sides and expanded metal construction meets OSHA specs. Box Construction Allows simple, onepiece, through-the-wall installation. 6 Electric Damper Operators Electric damper operators provide more positive open and closed damper positions which helps increase weather resistance. Power open-spring close (POSC) motor and linkage kits are field installed (except for center pivot style) and are available in 24, 120/240, or 460 volts (single phase ) and require approximately 0.5 amps at 120/1/60 power supply. Transformers are available for voltage reduction. For fan motors 5 hp and larger, we recommend a factory tilt switch or delay-on timer in the control circuit (by others) to allow the damper to open prior to allowing fan operation, which will protect the damper blades and fan from damage when the fan is first energized. Electrical Accessories are available to simplify the installation and reduce the total project cost. Disconnect Switches can be shipped loose or factory mounted and wired (except explosion proof) in NEMA 1, 3R, 4X, or other enclosures. Two-speed and explosion proof disconnects are available but may be subject to more stringent code requirments. It is the responsibility of the buyer and the installer to comply with all local and national codes. Two Speed Switch- A High/Low selector switch is available for use with two speed single phase motors and can be shipped loose or factory mounted and wired. Aluminum Construction is available for most models and typically includes propeller blades, fan panel, motor and drive support (large frame motors may have steel reinforcement) and accessories. When an explosion proof motor is specified, aluminum fan construction must be used for additional spark resistance. UL-705 Listing is available for sidewall propeller fans with most motors and should be specified for electrical safety and reliability. Extended Lube Lines provide convenient access for routine bearing lubrication. Lubrication lines are installed from the fan shaft bearings to the exterior of the wall housing or sheet metal motorside guard and are provided with Zerk fittings. Paints and Coatings include protective and corrosion resistant coatings such as air-dry, two part epoxy, phenolic (Heresite) and polyester resin, as well as decorative color finishes to match the building (a paint chip is required to match). Please note that our standard construction material specifications are almost exclusively galvanized steel and may not require any additional coating. Mounting Angles facilitate the installation and a secure attachment of the wall housing or wall collar into the framed wall opening. Galvanized or aluminum angles are available and are pre-cut to the proper length. Additional bracing, mounting hardware, flashing and caulking are typically provided by the installer. Factory Wiring can simplify jobsite installation and reduce the overall project cost. Optional services include wiring of motor, disconnect switch, speed control (when suitable), damper actuator, and other custom controls. Please note that some wiring options may not be available in conjunction with UL-705 listing option (for example, explosion proof and special motors).

7 Use the estimated pressure drop graphs to help select the proper exhaust or supply fan package that will deliver the desired airflow. Enter the graph from the bottom at the specified CFM and move vertically upward to the fan curve for the desired fan size, then horizontally to the left and EXHAUST AIRFLOW with WALL HOUSING GRAVITY DAMPER RAINHOOD MOTORSIDE GUARD Pressure Loss Guide for Accessories read the estimated static pressure drop resulting from these typical accessory packages. Add the accessory pressure loss to the system (or building) design static pressure loss to obtain the total static pressure loss to be used for the proper fan selection.

The fans shown are exhaust. Rainhoods are required on supply applications and recommended on exhaust applications where additional weather protection is desired. Exhaust and/or supply fans installed as shown should be serviced from the building interior. Field flashing and caulking of wall housing seams and unused mounting holes, will ensure a weather resistant installation. 7
