Radial Blowers

Industrial radial pressure blowers

RBO, RD, BP, LS, XO, DH, RTS, Radial Tip blowers: industrial radial blade blowers are supplied in welded heavy gauge steel construction to prevent flexing at high pressure. Available in direct drive arrangements 4/4V/4H/7/8 and belt drive blower arrangements 1/3/9/10. Arr. 10 blowers are known as ventilating sets (vent sets). Available in single width single inlet (SWSI), or double width double inlet (DWDI). Blower capacities: to 500,000 CFM. Static pressure up to 100 inches water gauge depending on the class of construction. Typical class of fan construction is Class 1, 2, 3, 4, 5.

Aluminum wheel, Steel wheel, or Alloy blower wheel: industrial radial blowers and fans are supplied with aluminum wheel or corten wheel to meet requirements of AMCA A, and AMCA B spark resistant fan construction. Mild steel blower wheels are of all welded construction. They are used on pressure applications, material handling fan applications (plastic scrap, paper trim, granular material, low density bulk material) where fan wheel is reinforced with support gussets, or made of abraision resistant construction, or furnished of high strenght steel. Stainless steel ventialtor 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 from fully open to fully closed position.

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

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

Heat fan construction up to 1500 F: includes high temperature paint (up to 1000 F), special alloy construction, shaft cooler, shaft-cooler guard, and steel wheel, or alloy wheel, with steel, or alloy housing.

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 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 inlet filter package.

Standard fan 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, evase, electrical / pneumatic actuators.

* Stainless steel construction of SST 316, SST 304 or SST 347 stainless alloy are available for corrosive applications

ABB Blower Square Fans incorporate non-overloading BI impeller desings: the motor can be sized for the operating horsepower of the fan and not oversized, thus increasing motor efficiency. Heavy gauge spinning inlet with airflow diverter permits smooth air flow and close wheel tolerances.

Three different wheel designs on CB SQB Square Fans provide the widest choice in applications suitability, efficiency, sound, and cost. All of them feature the backward inlcinged non overloading horsepower chracteristic, where the horse power curve reaches a peak and then decreases even as air flow increases. This feature allows maximum brake horsepower calculation and motor selection that prevents electrical system overloading even if system pressure changes.

True aerodynamic airfoil blade shape allows stable operation from wide open to closed off; ideal for clean iar applications such as building ventilation with variable air volume system control or clean industrial gas handling. Aerodynamic single surface blade shape of backward curve wheel offers alternative selction points to the Airfoil wheel and also provides stable operation from wide open to closed-off. Flat, single thickness backwardly inlined plades are suited for applications from clean air to those where dust and limited material is present in the airstream and where airfoil shapes are not recommended due to material build up that closes unbalance and vibration.
