The New York Blower Company

RFE - FRP RADIAL FUME EXHAUSTER

DESIGN FEATURES: The New York Blower Company’s FRP Radial Fume Exhauster [RFE] and FRP Pressure Blower [FPB] are designed so that all parts exposed to the airstream are constructed of high-quality corrosion-resistant fiberglass reinforced plastic. The RFE and FPB are resistant to attack from most chemicals and are ideally suited to applications in the chemical, pulp and paper, waste water treatment, fertilizer, pharmaceutical, and metal plating industries. Specifically, the RFE 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.

SIZE and PERFORMANCE DATA:RFE is available in five sizes: 160, 200, 315, 400, and 500 mm inlet-duct diameters [8”, 10”, 14”, 18”, and 22” wheel diameters]. Capacities to 7,500 CFM. Static pressures to 14”WG. Temperatures to 250°F. Available in compact Arrangement 10 design. FRP PB is available in three sizes: 18”, 22”, and 28” wheel diameters. Capacities to 5,000 CFM. Static pressures to 36”WG. Temperatures to 250°F. Choice of Arrangements: 1, 8, or 10. Choice of fiberglass or alloy wheel construction.

CONSTRUCTION FEATURES: Wheel is cast in a one-piece mold with a resin-glass mixture featuring premium-quality, corrosion-resistant vinyl ester resin. Solid FRP wheels are oven-cured to provide optimum strength and corrosion resistance. Radial-blade design provides stable, pulsation-free performance over the entire pressure range from wide open to closed-off. Standard shaft is ASTM A-108 steel, grade C-1040/1045. Inside the fan housing the shaft is covered with an FRP sleeve that is bonded to the wheel backplate and extends through the housing side, protecting the shaft from corrosive attack . . .316 SST shafting also available. Housing is made of premium-quality, corrosion resistant polyester 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 Voluntary Product Standard PS15-69 or ANSI Class 150 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 10 base features self-contained motor platform. Close-fitting, Teflon® shaft-hole closure limits the free exchange of gases through the shaft-hole opening. Neoprene gasketing at all bolted FRP joints. Fan exterior is coated with gray epoxy enamel. RFE 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 4167 Standard Specification for Fiber-Reinforced Plastic Fans and Blowers when fan is purchased with surface veil.

ACCESSORIES and MODIFICATIONS: SPECIAL ALLOY WHEEL AND SHAFT ASSEMBLIES— 316 stainless steel and Hastelloy® C-276 alloy wheel and shaft assemblies are available for applications where high moisture content may cause erosion of the standard FRP wheel. Available on Arrangement 1 and 8 FRP Pressure Blowers only. Shaft seal—Viton® elements in FRP casing. Type 316 SST sleeve covers shaft for use with seal. Optional Teflon seal and Hastelloy C-276 sleeve available. Outlet damper—corrosion-resistant FRP wafer-type damper sized to match FRP fan outlet flange. Damper flanges drilled as standard. Companion flange with collar—FRP construction; used on inlet or outlet to provide a slip connection for customer furnished flexible connection. Flanged drilling—for ease of direct connection; dimensions shown on page 10. Unitary base—available with spring or rubber-in-shear [R-I-S] isolators. Isolation rails are available for Arrangement 10 fans. Drain—threaded FRP drain with PVC plug, 1” npt, at lowest point of housing scroll. Inspection port—allows examination of fan interior. Located on inlet side half of housing at 2 or 10 o’clock, opposite discharge. Port size is 3” on RFE-160/200/315, and FPB-18/22; and 4” on RFE-400/500, and FPB-28. Surface veil—for added protection against certain corrosives. Provides compliance with ASTM D 4167. All-vinyl ester airstream—for additional protection from certain corrosives. Graphite impregnation—to control static electricity. The gas-stream surfaces are grounded to the fan base. Positive screw adjustment—two threaded rods provide easy motor platform/V-belt adjustment. [Arrangement 10 fans only.] Arrangement 10 weather cover/belt guard—provides motor and drive protection, and can be easily removed for inspection and maintenance. Louvered side panels provide ample motor ventilation. Safety equipment—belt guards and shaft and bearing guards are available for Arrangement 1 fans, and coupling guards for Arrangement 8 fans. Extended lube lines are furnished as standard with shaft and bearing guard. Drive components—a wide variety of motors, couplings, and v-belt drives are available from nyb.

SAFETY ACCESSORIES: Safety accessories are available from nyb, but selection of the appropriate devices is the responsibility of the system-designer who is familiar with the particular installation, or application, and can provide for guards for all exposed moving parts as well as protection from access to high-velocity airstreams. Users and/or installers should read “Recommended Safety Practices for Air Moving Devices” as published by the Air Movement and Control Association International, Arlington Heights, Illinois.

AMCA SEAL and LABELS: The New York Blower Company certifies that the FRP Radial Fume Exhausters and FRP Pressure Blowers are licensed to bear the AMCA Seal. The ratings shown are based on tests and procedures performed in accordance with AMCA Publication 211 and comply with the requirements of the AMCA Certified Ratings Program.

FRP Radial Fune Exhausters and FRP Pressure Blowers with Special Alloy Construction: airstream components, blower pedestal, guards, and unitary base can be constructed of a wide range of alternate alloys for corrosive applications: 950X/960X alloy; 980X alloy, aluminum, high strength aluminum 6061-T6 ; Monel, 304 stainless steel, 316 stainless steel, 2205 stainless steel, corten, etc.

FRP Radial Fume Exhaisters and FRP Pressure Blowers Protective Coatings: Cost-effective protective coatings under a variety of trade names are available to increase the fan’s resistance to adverse, corrosive environments.

FRP Blowers Drive components: motors, couplings, and v-belt drives, as well as a variety of preventive-maintenance products including vibration detectors, bearing-temperature detectors, and zero-speed switches are also available.
