9-M Mounting Positions viewed from discharge end Fabricated mounting legs facilitate fan mounting on the floor, ceiling, or in a vertical position on a wall. Flange connections are standard. Fans are equipped with four mounting brackets suitable for floor, platform, or ceiling mounting. Motor is located on centerline between two of the four brackets. Flange connections are standard. Units feature flanges on inlet and discharge for mounting to the duct work. Roof-mounted fans are furnished with curb caps and collars extending below the curb cap for easy connection. Stackhoods and weather...

ACCESSORIES AND MODIFICATIONS 1. INLET BELL WITH GUARD Arrangement 9-M with inlet bell with guard, weather cover, motor, and V-belt drive. Inlet bell minimizes losses associated with non-ducted inlet applications. Includes wire guard. 2. VIBRATION ISOLATION – not shown Rubber-in-shear or spring-type isolation mounts reduce the transmission of vibration to the mounting structure. 3. SAFETY EQUIPMENT/WEATHER COVER Belt guards are included as standard. Inlet and outlet guards, and louvered weather covers are available. Selection of appropriate safety accessories is the responsibility of the...

INLET BELL Catalog ratings shown in this bulletin are for Vaneaxial Fixed Pitch Fans with free inlet and ducted outlet. When no inlet duct is used, entrance loss must be added to the static pressure calculated for the system. For bare inlets, that loss is equal to the fan velocity pressure. Example: 4200 FPM velocity = 1.1 "WG [see Chart I at right]. Inlet bells render such loss negligible and are available at nominal cost. Sizes 12 through 48 constructed of fiberglass reinforced plastic; Sizes 54 and 60 constructed of steel. Available for all sizes of Vaneaxial Fixed Pitch Fans with...

For a given fan size, CFM, and static pressure, capacity tables can be used to obtain outlet velocity, fan RPM, and BHP If capacities are at conditions other than 70°F, sea level, or standard density [.075 lb./cu. ft.], correction factors must be applied to static pressure and BHP Chart II details maximum safe speed of standard wheels at 70°F. When temperatures are involved, multiply the appropriate safe operating speed shown in Chart II by the factor shown in Chart III. Maximum operating temperature for standard fans is 120°F. For temperatures above 120°F, as indicated by tinted areas in...

Belt-Drive Vaneaxial Fixed Pitch Fans Belt-drive Vaneaxial Fixed Pitch Fans are available in Sizes 12 through 60. Standard Design is provided less a belt well for improved airflow performance and efficiencies. For applications requiring sealed drives, spark-resistant construction, or temperatures in the range of 120 to 200 degree F, fans can be furnished with an optional belt well to isolate the bearings and drive components from airborne moisture and contaminants. In the event that system pressures or flow requirements change, belt-drive Vaneaxial fans offer inherent performance...
