Available in direct drive arrangements 4/4V/4H/7/8 and belt drive arrangements 1/3/9/10. Arr. 10 blowers are known as ventilating fan sets (vent sets). Available in single width single inlet (SWSI), or double width double inlet (DWDI) ventilators wheels. Capacities: to 500,000 CFM. Static pressure up to 100 inches water gauge depending on the class of construction. Typical class of construction is Class 1, 2, 3, 4, 5.

Aluminum wheel, Steel wheel, or Alloy wheel: industrial backward inclined (bi) blowers and fans are supplied with aluminum fan wheel or corten wheel to meet requirements of AMCA A, and AMCA B spark resistant construction. Mild steel ventilator wheels are of all welded construction. If higher pressure is required wheel can be furnished of high strenght steel. Stainless steel wheel in 304 SS, 316 SS, 316 SS, 2205 SS are supplied for corrosive applications, or high temeparature fan applications. The pressure curve remains stable to the right of the pick point.

Inlet flanges, outlet flanges, companion fan flanges: continuosly welded to match ANSI class 125/150, DIN, ISO, or custom hole pattern.

Shaft seal and low leakage fan construction: shafting is straightened to close tolerance to minimize "run-out" and ensure smooth operation. Teflon shaft seal, ceramic fan shaft seal and lubricated shaft seals (Buna, Teflon, Viton) are standard. Red silicone gasketing is provided for low leakage construction and for high temperature construction.

Heat fan construction up to 800 F: includes high temperature paint, shaft cooler, shaft-cooler guard, and steel fan wheel, or alloy wheel.

Cladding for sound attenuation and silencers: cladding consists of 2 inches mineral-wool insulation covered with a welded steel jacket. As an inexpensive alternative is offered slide-on acoustic cloth jackets. Inlet silencer / outlet fan silencer are supplied with matching flanges for further attenuation of the noise level.

Inlet filter assemblies: cell type, 1 inch, or 2 inch filters are available with filter cabinet to be mounted at fan inlet. Bird guard, insect screen and weather hood are optional accessories with blower's inlet filter package.

Standard accessories:flash / raised access door, inspection port, drain and plug, unitary base, shaft and bearing guard, belt guard, motor cover, spring vibration isolation, rubber-in-share (RIS) vibration isolation, vibrating pads, outlet damper, inlet vane damper, external inlet vane damper, electrical / pneumatic actuators.

Controls and drives: variable frequency drives (VFD), across-the-line starters, RTDs, pressure sensors, flowmeters - complete control packages.

The purpose of an industrial fan is to provide a large flow of air or gas to various processes. This is usually directed through a rotation of blades which are connected to a hub/shaft, and driven by a motor.

Industrial Fan Basics

There are numerous uses for the continuous flow of air or gas that industrial fans generate, including: combustion, ventilation, exhaust, and particulate transport to name a few. Fans operate in both clockwise and counterclockwise orientations, and common accessories for fans include: flanges, shaft seals, belts, and bearing guards. Belt/shafts and bearing guards are extremely important as OSHA requires it – they are an absolute must !

The Two Primary Types of Industrial Fans are:

Centrifugal Fans

Centrifugal fans utilize what’s known as a “centrifugal force” generated by a rotating disk, with blades mounted at the right angles to the disk, to impart movement to the air or gas stream and increase its pressure. In contrast to axial fans, centrifugal fans/blowers use wheels rather than propellers. The centrifugal fan wheel is typically contained within a scroll-shaped fan housing. The air or gas inside the spinning fan is thrown off the outside of the wheel to an outlet at the housings’ largest diameter. There are a variety of centrifugal fans, which may have fan wheels that range from less than a foot to over 16 feet.

Axial Fans

An axial fan design utilizes axial forces to achieve the movement of the air or gas, spinning a central hub with blades extending radially from its outer diameter. Unlike the centrifugal fan, axial fans utilize propellers rather than wheels. The axial fan is often contained within a short section of cylindrical ductwork, to which inlet and outlet ducting can be connected. Axial fan types have fan propellers with diameters that usually range from less than a foot to over 30ft. Simply put, axial fans are used where the principal requirement is for a large volume of flow, and the centrifugal design where both flow and higher pressures are required.
There are numerous subset designs within each of these groups to meet the specific needs of your process (backward-inclined, shrouded radial, paddle wheel, air foil, tube axial, etc…).
