Fans And Blowers Noise Level   By: oleg tchetchel
Fan blade pass frequency is a pure tone produced when the blades of the fan wheel (impeller) rotate past the housing cut-off sheet in centrifugal fans, or the turning vanes, in axial fans. The blade pass frequency is calculated by multiplying the number of blades times the rotating speed in revolutions per minute. If this frequency matches the natural frequency of the ductwork, it can excite the ductwork, which can cause it to resonate, thereby increasing the noise level. Because of this possible increase in sound, and because certain pure tones are irritating to people, the sound output of the blade pass frequency should be investigated when sound reduction is desired. The next factor to consider is the fan design. Generally a fan operating at peak mechanical efficiency will produce less noise, because high efficiencies result from minimal air turbulence within the fan.(read entire article)

Fiberglass Pressure Blower   By: oleg tchetchel
Potential applications for FRP fans include any process in which corrosive fumes must be captured, moved, cleaned, or vented. FRP fans are most often used in fume-scrubber systems where the scrubber itself may be constructed of FRP or an exotic alloy, but where FRP is the preferred fan material. Galvanizing and etching processes often have FRP exhaust hoods and ducts, and many of the fans used to convey fumes in such systems are also built of FRP. Waste water treatment plants and laboratory exhaust systems are other applications for which FRP fans are being used with increasing frequency.(read entire article)

Ventury Fume Scrubbers   By: oleg tchetchel
Venturi fume scrubbers wash dust and particles out of the air by forcing the air into a spray chamber, where fine water particles cause the dust to drop from the air stream. Where applied, venturi scrubber technology is able to achieve the highest particulate collection efficiency of any wet scrubbing system.(read entire article)
