FP ADIAL FUME EXHAUSTES DESIGN FEATUES The New York Blower Company s FP adial Fume Exhauster [FE] and FP Pressure Blower [FPB] are designed so that all parts exposed to the airstream are constructed of high-quality corrosion-resistant fiberglass reinforced plastic. The FE and FPB are resistant to attack from most chemicals and are ideally suited to applications in the chemical, pulp and paper, wastewater-treatment, fertilizer, pharmaceutical, and metalplating industries. Specifically, the FE is designed for exhausting moderate volumes of highly corrosive fumes at moderate pressures. Typical applications include laboratory fume hoods, small plating and pickling operations, etching processes, and chemical-fume scrubbers. The FPB is designed for low volumes at high pressures. Typical applications include pulp and paper processes, chemical-fume scrubbers, and soil remediation. FP ADIAL FUME EXHAUSTES Five sizes: 60, 200, 5, 400, and 500 mm inlet-duct diameters [8, 0, 4, 8, and 22 wheel diameters]. Capacities to,500. Static pressures to 4 WG. Temperatures to 250 F. Available in compact Arrangement 0 design. FE-400, Arrangement 0, clockwise Up Blast, with optional motor and v-belt drive. FE radial FP wheel. AMCA SEAL The New York Blower Company certifies that the adial Fume Exhausters shown herein are licensed to bear the AMCA Seal.

AND PESSUE BLOWES CONSTUCTION FEATUES Wheel is cast in a one-piece mold with a resin-glass mixture featuring premium-quality, corrosion-resistant vinyl ester resin. Solid FP wheels are oven-cured to provide optimum strength and corrosion resistance. adial-blade design provides stable, pulsation-free performance over the entire pressure range from wideopen to closed-off. Standard shaft is ASTM A-08 steel, grade C-040/045. Inside the fan housing the shaft is covered with an FP sleeve that is bonded to the wheel backplate and extends through the housing side, protecting the shaft from corrosive attack... 6 SST shafting also available. Housing is made of premium-quality, corrosionresistant vinyl ester resin. The interior is extremely smooth, due to fabrication on male molds. Flanged inlet and outlet for easy in-duct connection; supplied without holes as standard. Flange drilling available in choice of National Bureau of Standards oluntary Product Standard PS5-6 or ANSI Class 50 lb. patterns. All fans are rotatable to any of six discharge positions. Lifting eyes on all fans for ease of handling. Welded-steel base is constructed of heavy-gauge components for structural strength and durability. Arrangement 0 base features self-contained motor platform. Close-fitting, Teflon shaft-hole closure limits the free exchange of gases through the shaft-hole opening. [Teflon is a registered trademark of DuPont.] Neoprene gasketing at all bolted FP joints. Fan exterior is coated with gray epoxy enamel. FE and FPB wheels are dynamically balanced before final assembly. After assembly, all fans are given a final balance check at the specified running speed. Meets ASTM D 46 Standard Specification for Fiber- einforced Plastic Fans and Blowers when fan is purchased with surface veil.

HOW TO USE PEFOMANCE TABLES For a given fan size,, and static pressure, capacity tables can be used to obtain outlet velocity, wheel PM, and BHP. If capacities are at conditions other than 0 F., sea level, or standard density [.05 lbs./cu.ft.], correction factors must be applied to static pressure and BHP. STEPS TO FOLLOW Determine fan static pressure at standard conditions. If temperature or altitude is involved, correct for air density [see Charts I and II]. Select size, PM, and BHP of fan from capacity tables. Check the maximum safe speed of the fan shown below in Chart III. Apply temperature maximum safe speed factors from Chart I to maximum safe speed of fan from Step to determine new maximum safe speed when temperature is involved. Determine actual performance by dividing static pressure and BHP* from Step 2 by the correction factor in Step. STEPS EXAMPLE: *NOTE: Motor should be selected for BHP @ 0 F. to insure proper operation during cold starts. FE-400 fan to handle 2400 at 8 WG at 200 F. at sea level. Chart I shows.25 correction factor for 200 F. 8 WG x.25 = 0 WG at 0 F. Capacity table shows 265 PM,. BHP for FE-400 fan at 2400 at 0 WG at 0 F. Maximum safe speed of FE-400 fan is 050 PM at 0 F.

IN COOSION-ESISTANT FP FANS... STANDADS MAKE A DIFFEENCE! In FP Fans, construction quality and accurate air ratings are vital. That s where standards make a big difference. The American Society for Testing and Materials [ASTM] developed a standard specification for FP fans and blowers. ASTM D 46, Stan - dard Specification for FIBE-EINFOCED PLASTIC FANS AND BLOWES, defines minimum specifications for construction of major fan elements. It is a concise, understandable, readily available standard. The Air Movement and Control Association s [AMCA] Certified atings Program provides assurance of accurate ratings. AMCA Standard 20 describes how fans are to be tested for air performance. The AMCA Certified atings Program requires the fan manufacturer to guarantee aerodynamic performance within close tolerances of the manufacturer s published ratings. The Society of the Plastic Industry s [SPI] Users Guide to P Industrial Equipment, #2-Fans, Guide for Purchasing or Specifying einforced Plastic Fans and Blowers, recommends specification of both the ASTM and AMCA standards. The New York Blower Company s complete line of FP Fans Fume Exhausters, adial Fume Exhausters, Pressure Blowers, General-Purpose Fume Exhausters, and Tubeaxial Fans meet these standards.
