Tubeaxial Fans (industrial tubeaxial ventilators)
Tubeaxial fans are axial flow
through fan designed for low pressure building ventilation and
industrial process blower application. Ventilator uses include
heat, smoke, and fume
removal; process ventilation and process air handling; process blower
drying
with ambient or preheated up to 650 F air; comfort process cooling and
general ventilation of buildngs. Available in direct drive arrangements
4/4M/4V/4D/4R and corresponding belt drive
arrangements 9/9M/9V/9D/9R. Capacities: to 350,000 CFM. Static pressure
to
4 inches water gauge.
Tubeaxial
fans are designed to handle a wide range of requirements from
general ventilation to process air supply. The mounting flexibility
makes them an ideal choice for many industrial and commercial
applications. Units are available as direct or belt driven, with steel
or aluminum impellers that are fixed or adjustable blade pitch.
Vaneaxial fans are designed for applications where large volumes of air
are required at moderate to high pressures. Direct and belt driven
models, with fixed and adjustable blade impellers, are available. The
tubular design and high
impeller efficiency provides maximum performance while using minimal
space.

Aluminum wheel, Steel wheel, or Alloy wheel: tubeaxial fans for non-sparking x-proof applications is supplied in AMCA A, AMCA B, or AMCA C spark resistant construction in all aluminum welded construction, or in monel. For corrosive environment tubeaxial fan is supplied in 304 SS, 316 SS, or 316 L stainless steel construction. For chemical process applications tubeaxial fan is available in fiber reinforced plastic (FRP) construction, or in polypropylene construction, or in plastic. For high temperature applications up to 650 F tubeaxial fan is supplied typically in steel welded construction.
Inlet flanges, outlet flanges, companion flanges: continuosly welded to match ANSI class 125/150, DIN, ISO, or custom hole pattern.
Shaft seals: tubeaxial shafting is straightened to close tolerance to minimize "run-out" and ensure smooth operation. Bearings are of pillow plock, or flaged bearings. Ceramic shaft seal and lubricated shaft seals (Buna, Teflon, Viton) are standard. Red silicone gasketing is used on high temperature applications.
Heat fan construction up to 850 F: includes high temperature paint, shaft cooler, shaft and bearing tunel cooling auxiliary blower (optional), insulated shaft and bearing tunel, steel, or alloy wheel.
Cladding for sound attenuation and silencers: cladding consists of 2 inches mineral-wool insulation covered with a welded steel jacket. Acoustic cloth jackets are available as inexpensive alternative. Inlet silencers/outlet silencers are supplied with matching flanges.
Inlet vane damper assembly: external inlet vane damper is provided for precise air volume control.
Standard accessories include: flash / raised access door, inspection port, drain and plug, 3-way drain, mount feet, belt guard, motor cover, spring vibration isolation, rubber-in-share (RIS) vibration isolation, vibrating pads, electrical actuators, pneumatic actuators.
Roof mount accessories available: roof curb mount cap, roof curb, weather band, weather shroud with integral flap damper, butterfly damper assembly, magnetic latches.
Easy Access Construction option:
for wash-down duty applications: tube casing is of split open hinged
construction and allows for direct access to the wheel-shaft-bearings
and drive.
