1 ARRANGEMENT 4/4F/4H/4V SINGLE-WIDTH ACOUSTAFOIL/PLR FANS 13 Class PLR Arr. 4 Fan, CW rotation with top angular up discharge. APPLICATIONS With three classes to choose from, the Arrangement 4/4F/4H/4V Single-Width AcF/PLR Fans are ideally suited for a wide range of clean-air applications. They are typically used for: air-drying, product cooling, product drying, combustion air, supply and exhaust, fume control and on the clean-air side of dust collection systems. DESIGN FEATURES Sixteen sizes... 1 to 49 wheel diameters. Pressures up to 34 WG. Capacities from 38, to 7,. Operating temperature to 18 F. on Arrangement 4 fans. Operating temperatures to 1 F. on Arr. 4F/4H/4V fans. Efficiencies beyond 8%. Eliminates shaft and bearings for minimum maintenance. Choice of AcoustaFoil, PLR, or C wheels. Unique inlet cone with airflow diverter improves fan efficiency. Narrow-width wheel designs permit higher speeds and pressures. Class 3 PLR Arr. 4V Fan, CW rotation. CONSTRUCTION FEATURES Welded construction - heavy-gauge welded components provide structural strength and durability for extended service life in a wide range of applications. Housing - continuously welded for the strongest possible construction. Precision balancing - all AcoustaFoil, PLR, and C wheels are dynamically balanced before final assembly. After assembly, all fans are fine-tune balanced on a rigid test fixture at the specified running speed. Finish - two-coat paint system consisting of one prime coat and one finish coat of nyb green air-dried enamel. Lifting eyes - standard on all models... sized and located for ease of handling. Optional accessories - numerous fan accessories are available to meet application requirements including: motors, variable frequency drives [VFDs], inlet and outlet guards, flanged inlets and outlets, drains, outlet rainhoods and more. Consult your New York lower representative for a complete list. CS-13 Form 7 MJN

2 DIRECT-DRIVE FAN SELECTIONS It is often most cost-effective to use direct-drive fans due to reduced bearing loads and maintenance. However, a major objection to direct-drive arrangements in the past was the inability to adjust fan speed if system requirements changed. With the advent of variable frequency drives [VFDs] the speed, and therefore performance of direct-drive fans can now be adjusted to meet varying process requirements. Dampers are also available when required. ARRANGEMENT 4/4F/4H/4V FANS With the fan wheel directly mounted on the motor shaft, speed limitations imposed by the fan s shaft and bearings are eliminated. In addition, fan maintenance is further reduced by the elimination of these components. The maximum temperature for Arrangement 4 fans is 18 F. The maximum temperature for Arr. 4F/4H/4V fans is 1 F. The Arrangement 4 fans utilize a foot-mounted motor, whereas the Arr. 4F/4H/4V fans utilize a c-face motor. WHEEL SPEED VS. WIDTH A major component in the determination of wheel maximum safe speed is blade strength. Narrower wheels are inherently stronger permitting higher wheel maximum safe speeds. The direct-drive performance curves shown on pages 3, 4, and illustrate maximum performance capabilities with fullwidth wheels [solid lines] and maximum performance capabilities with narrow-width wheels [dotted lines] at 7 F. Final selection of direct-drive AcF/PLR Fans can only be optimized using nyb Electronic Catalog software. PRELIMINARY FAN SELECTION Following the engineering and selection guidelines presented on page 6 and 7, use the corrected capacity [] and pressure [ WG] to determine which AcF/PLR Fan sizes and classes can meet the performance requirements. The directdrive performance curves on pages 3, 4, and illustrate maximum pressures and capacities at 7 F. Any performance point under the curves can be attained using a VFD and reducing RPM. Generally, the smallest size and lowest class [CL., CL. 3, CL. 4] will be the least expensive; however, a larger size and class will generally be more efficient requiring a less expensive motor and controls, as well as offer significant operating cost savings. To determine the optimum fan at a specific point of operation, nyb Electronic Catalog software must be used [see description below]. To obtain a copy contact your New York lower sales representative or nyb at ELECTRONIC CATALOG Fan-selection program corrects for altitude, temperature, rarefication, adjusts maximum safe speed for wheel width, and generates performance curves. Also includes complete product literature, guide specifications, installation and maintenance literature, Engineering Letters, web-site launch, and a listing of New York lower sales representatives.

Flush mounted by inlet to customer s mating surface. (Up to size 33) GENERAL The direct-drive performance curves shown in this catalog sheet will guide the designer to potential fan sizes and models. It is recommended that final selection be made using New York lower s Electronic Catalog software and that a New York lower sales representative be consulted for assistance in optimizing the selection. CORRECTION FACTORS Fan performance is based on actual cubic feet per minute [A] at the fan inlet at standard density [.7 lbs./ft. 3 ] and static pressure at the fan outlet. Static pressure capabilities are shown in inches water gauge [ WG]. Air-density corrections are necessary for proper selection when air density varies from the standard.7 lbs./ft. 3 at 7 F. at sea level. This also occurs when negative static pressure exists [rarefication] on the inlet side of the fan. Multiply the required static pressure at operating conditions by the appropriate factors in Charts III, IV, and V to obtain the corrected static pressure for standard conditions. Pressure and HP will be reduced at conditions by the inverse of these factors. Multiply one factor by the other if temperature, altitude, and rarefication are non-standard. For example: if the installation is located at an altitude of 4 feet, the gas temperature is 1 F. and the inlet pressure is - WG, the correction factor is 1.33 [1. x 1.9 x 1.].
