Industrial vaneaxial ventilators
Vaneaxial fans: axial flow through fans designed for
medium and high pressure building ventilation, mining ventilation,
industrial ventilation and industrial process application. Ventilators
applications include
heat, smoke, and fume removal; process ventilation and process air
handling; proces drying with ambient or
preheated up to 650 F air; comfort process cooling and general
ventilation of buildngs. Available in direct drive ventilator
arrangements
4/4M/4V/4D/4R and corresponding belt drive arrangements 9/9M/9V/9D/9R.
Fan capacities: to 350,000 CFM. Static pressure to 14 inches water
gauge.
Available in two stage blower configuration.
Canada Blower VAD Direct Drive
Vaneaxial Type VANAX Fan
American CoolAir Type VanAx vaneaxial VAD fans are true vane axial fans
designed for a wide range of commercial and industrial applications.
High pressure efficiency permits the fans to be installed anywhere in
the system — in any position. The fans can be used for either supply or
exhaust by simply turning the entire unit to move air in the desired
direction. Canada Blower Vanax fans are extremely compact and well
suited to locations where space is limited, and can often be easily
mounted directly to the ductwork. As a result of very close tolerances
and carefully matched vanes and rotors, Vanax fans offer exceptional
performance across its size ranging from 12 to 60. VAB fans are rated
from 1,200 to 47,000 CFM and static pressures up to 4”.
VAD Construction: CoolAir Model VAD feature a rolled steel casing with
a die formed steel vane section. Both the steel casing and vane
sectionare coated with a protective epoxy paint finish. The vane
section for both Canada Blower VA and VAD also serves as the motor
mount for the fan, and the cast aluminum rotor is mounted directly to
the motor shaft. This direct drive arrangement provides years of
maintenance-free service. The cast aluminum rotor is mounted directly
to the motor shaft.
Aluminum wheel, Steel wheel, or Alloy fan wheel: vaneaxial fan for non-sparking x-proof applications is supplied in AMCA A, AMCA B, or AMCA C spark resistant ventilator construction in all aluminum welded construction, or in monel. For corrosive environment vaneaxial fan is supplied in 304 SS, 316 SS, or 316 L stainless steel fan construction. For chemical process applications vaneaxial fan is available in fiber reinforced plastic frp construction, or in polypropylene construction, or in plastic. For high temperature applications up to 650 F vaneaxial 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.
Fan shaft seals: vaneaxial 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 650 F: includes high temperature paint, shaft cooler, shaft and bearing tunel cooling auxiliary blower (optional), insulated fan 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 fan silencers are supplied with matching flanges.
Inlet vane damper assembly: external inlet vane damper is provided for precise air volume control.
Standard accessories: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: roof curb mount cap, roof curb, weather band, weather shroud with integral flap damper, butterfly damper assembly, magnetic latches.
Controls and drives: all standard controls available.
