FRP Pressure
Blowers
FRP Pressure
Blowers
are designed for highly corrosive application to handle acid vapors,
and organic and inorganic chemical fumes that are highly corrosive to
metal at temperatures up to 250 F. Fan applications include scrubber
systems, odor control systems in wastewater treatment plants,
laboratory exhaust systems, metal finishing and chemical-process
industries. Fiber-reinforced-plastic pressure blowers are made from
chemical grade polyester or vinyl ester resins and reinforced with
glass or fiber. Additional surface veil is available depending on the
application. Capacity range of FRP Pressure Blowers is from 0 to 8,000
CFM and static pressure range is up to 40” WG.
Housings of FRP
Pressure Blowers are rotatable and fabricated of polyester resin based
FRP , while
FRP fan wheels are made of vinyl ester resin FRP to allow for more
strength.
316 stainless steel, or Hastelloy C-276 alloy wheel and shaft
assemblies are available. FRP ORB self-cleaning wheel design and FRP
Pressure Blower wheel design are used depending on application.
Standard fan shafts are made of C-1040/1045 steel covered with FRP
sleeve.
316 stainless steel shafts are optional. Inlet/outlet flange drilling
is according to ANSI 125/150 bolt pattern, or Voluntary Product
Standard PS15-69. Neoprene gasketing with Teflon Shaft Seal, or Viton
seal element in FRP casing is provided where low leakage is desired.
FRP Pressure
Blower Accessories include outlet flanged wafer-type damper, made of
FRP; inlet vane damper in FRP construction; companion flange with
collar
in FRP construction; unitary base available with spring or
rubber-in-shear RIS isolator ; drain and plug threaded FRP drain with
PVC plug; inspection port ; surface veil provided in compliance with
ASTM D 4167; all-vinyl ester airstream; graphite impregnation to
control static electricity; adjustable motor base ; OSHA Guards and
Motor weather cover; drive components; VFD duty high efficiency motors;
and others.
Teflon
Impregnated Flexible Connectors to isolate FRP pressure blower and to
allow for mis-alingment of piping.
FRP Blower
Silencers
are offered as inlet and discharge silencers with FRP sound absorbing
elements. 304, 316 stainless steel options are available as well.
Controls and
drives:
variable frequency drives (VFD), magnetic motor starters, are available
in NEMA 1, NEMA 3R, NEMA 4 enclosure, as well as complete set of
electrical components for x-proof fan applications.
