HOUSINGS Housings are designed to maximize performance with either AcoustaFoil or PLR wheels. Housings are continuously welded and furnished with mounting studs on both sides of the housing for easy installation. • 13 sizes from 10” to 36”. • AMCA Class I, II, and III construction. • Rotatable • Clockwise or counterclockwise. INLET CONES Aerodynamically designed, spun inlet cones are matched for optimum efficiency with wheel and housing components. Reduced depth inlet cones, for space restricted applications, are also available in a limited size range. • 22 sizes from 10” to 89”. • Available with or without diverters. • Reduced depth cones Sizes 18 to 49. • Mounting holes for ease of installation. Fan Components The New York Blower Company has provided air-handling equipment to the construction and process industries for over 100 years. The same housings, wheels, and inlet cones used in AcoustaFoil and PLR Fans are available to original-equipment manufacturers to meet a full range of air-flow and pressure requirements. These components offer system designers a variety of configurations limited only by the needs of the system and good engineering practice. WHEELS Two backwardly inclined wheel designs are available to match a broad range of application requirements. AcoustaFoil wheels are available for clean, dry airstreams requiring superior efficiency and low sound levels. PLR wheels are provided for moist or mildly contaminated airstreams. • 22 sizes from 10" to 89" in diameter • Static pressures to 20" WG. • AMCA Class I, II, III, and IV construction. • Temperatures to 800°F. • Capacities to 350,000 CFM. TEMPERATURE AND CORROSIVES Special alloys and protective coatings are available for high-temperature or corrosive applications. Alloy construction: AcoustaFoil/PLR wheels, housings, and inlet cones can be constructed of aluminum or stainless steel in addition to standard carbon steel construction. Coatings (up to 12 mils thickness): Special paints and spray coatings are available under a variety of trade names. New York Blower works with experienced coating applicators who can apply coatings to meet a wide range of requirements. THE NEW YORK BLOWER COMPANY 7660 Quincy Street Willowbrook, IL 60527-5530

WHEEL WEIGHTS [lbs.] Size AcoustaFoil * Standard construction is aluminum, not available in steel or other alloy construction. NA - Not Available

BORE RANGE BY WHEEL SIZE NOTE: Straight bores to fit shafts for NEMA motor frames 143T through 445T, metric bores, and taper bores are available, provided bore size does not exceed largest bore as shown above. Contact nyb for special bore sizes and for taper bores. f Maximum safe speeds apply only to wheels operated at or below 70°F. and NA - Not Available free of material build-up, corrosion, or wear.

Above dimensions apply to full-width wheels only. STANDARD DEPTH INLET CONE DIMENSIONS [inches] Selection criteria: The reduced depth inlet cone is suitable for all unhoused wheel applications (Sizes 18-49) where a standard inlet cone can be used with the following exceptions: 1) Applications where the wheel must be removed through the inlet. 2) Applications where the minimum d/D ratio for wheels in a plenum is less than .2...see Plug Fan bulletin. ■ Performance losses occur with Size 18, 22, and 24 reduced depth inlet cones. To determine performance, apply the % derate to...
