DESIGN FEATURES TUBEAXIAL FANS Tubeaxial Fans are designed and constructed for moderate pressure ventilating and industrial process applications requiring the compactness of an axial fan. • Capacities—to 86,000 CFM. • Pressures—to 3"WG. > Thirteen sizes—12" through 60" wheel diameters. • Choice of arrangements—direct-drive or belt-drive arrangements in five mounting positions [see page 6]. • Precision rolled tube—for minimum tip clearance... maximum efficiency. Cast aluminum wheel —airfoil-shaped blades assure most efficient operation. Heavy-gauge welded components—provide...

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

1. INLET BELL WITH GUARD-see page 5 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. 3. SAFETY EQUIPMENT/WEATHER COVER Belt guards, inlet and outlet guards, and weather covers are available. Selection of appropriate safety accessories is the responsibility of the system designer familiar with the specific installation. 4. COMPANION FLANGES —not shown Fit flush with fan inlet and outlet flanges,...

INLET BELL Catalog ratings shown in this bulletin are for Tube-axial Fans with free inlet and ducted outlet. When no inlet duct is used, en-trance 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 128 through 488 constructed of fiberglass reinforced plastic; Sizes 548 and 608 constructed of steel. Available for all sizes of Tubeaxial Fans with matching standard...

Mounting Arrangements! ARRANGEMENTS WITH MOUNTING LEGS 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 on Arrangement 9. Flange connections are standard. Units feature flanges on inlet and discharge for mounting to the duct work. Tubeaxial Fans are available packaged with stack hoods and curb...

For a given fan size, CFM, and static pressure, capacity tables can be used to obtain outlet velocity, fan RPM, and BHR If capacities are at conditions other than 70°F, sea level, or standard density [.075 Ib./cu. ft.], correction factors must be applied to static pressure and BHR Maximum Safe Speed Information 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 Arrangement 4 fans is 105°F and for standard...

Available in Sizes 128 through 608, the direct-drive Tube-axial Fan is ideally suited for relatively clean-air applications at temperatures to 105° F. Elimination of external motor mounting structure permits installation in extremely tight locations and reduction in overall unit weight. The Arrangement 4 configuration virtually eliminates all regularly scheduled maintenance. External inlet vane dampers and variable frequency motor controllers are available to modulate airflow in process or commercial air-conditioning systems.

Belt-Drive Tubeaxial Fans Belt-drive Tubeaxial Fans are available in Sizes 128 through 608 for more aggressive air streams or applications where temperatures may reach 200°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, belt-drive Tubeaxial Fans offer inherent performance flexibility. New performance is easily achieved by modifying readily accessible drives. Performance shown is for installation Type B: Free inlet,...

Performance shown is for installation Type B: Free inlet, Ducted outlet. Power rating (BHP) does not include drive losses. Performance ratings do not include the effects of appurtenances in the airstream.
