APPLICATION ADVANTAGES New York Blower’s Industrial Duct Fans are designed for low-pressure ventilation and industrial-process applications. Uses include heat, smoke and fume removal; paint booth exhaust; process drying with ambient, preheated air; oven exhaust; comfort and process cooling and general ventilation. All applications can be handled in either supply or exhaust configurations. Numerous modifications and accessories make the Industrial Duct Fan suitable for a wide range of applications and systems. In applications where equipment space is at a premium, the compact flow-through...

ACCESSORIES AND MODIFICATIONS 1. INLET BELL WITH GUARD – pictured on the left Inlet bell minimizes losses associated with non-ducted inlet applications. Includes wire guard. 2. VIBRATION ISOLATION – see page 6 Rubber-in-shear or spring-type isolation mounts reduce the transmission of vibration to the mounting structure. With optional weather cover, bell mouth inlet and inlet guard. (inspection door is standard). 3. SAFETY EQUIPMENT/BELT GUARDS/ WEATHER COVER & INLET/OUTLET GUARDS Belt guards, inlet and/or outlet guards, and weather covers are available. Selection of appropriate safety...

INLET BELL Catalog ratings shown in this bulletin are for Industrial Duct 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. Chart I VELOCITY PRESSURE Available for all sizes of Industrial Duct Fans with matching standard flanges for either inlet or outlet applications. Silencers are available in two...

MOUNTING ARRANGEMENTS Arrangement 9-M with motor, drive, belt guard, inlet bell and outlet guard (inspection door is standard). 9-M Mounting Positions viewed from discharge end WITH MOUNTING LEGS Arrangement 9-S with optional spring isolation. Fabricated mounting legs facilitate fan mounting on the floor, ceiling, or in a vertical position on a wall. Flange connections are standard. VERTICAL MOUNTING 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. Standard construction includes...

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

Belt-drive Industrial Duct Fans are available in 10 Sizes ranging from 12 through 48 for aggressive airstreams and applications where temperatures may reach 375°F. Belt-drive arrangements include a shaft, bearings, and belt-well assembly that isolates bearings and drive components from airborne moisture and contaminants. In the event that system pressures or flow requirements change, Industrial Duct Fans offer inherent performance flexibility. *Wheels available on application with 304 SST or 316 SST blades at same capacity.
