| Industrial Pressure Blower Co. now makes a new | | | | temperature fan construction with a shaft cooler |
| design of a centrifugal general ventilating fan - Square | | | | assembly and high temperature paint * Flanged inlet |
| Fan, in direct drive and belt drive configurations. | | | | and outlet * Stainless steel construction of SST 316, |
| Arrangement 4 direct drive square fans are ideally | | | | SST 304 or SST 347 stainless alloy are available for |
| suited for a wide range of clean-air applications reuiring | | | | corrosive applications |
| a tight footprint. Typical uses include pneumatic | | | | Industrial Pressure Blower Co. Square Fans |
| conveying, product drying, process cooling, and | | | | incorporate non-overloading BI impeller desings: the |
| exhaust on clean-side of dust collection systems. | | | | motor can be sized for the operating horsepower of |
| Some design features of the Industrial Pressure | | | | the fan and not oversized, thus increasing motor |
| Blower Co. Square Fans include: | | | | efficiency. Heavy gauge spinning inlet with airflow |
| - Ten sizes from wheel size 10" to 30" - Capacities up | | | | diverter permits smooth air flow and close wheel |
| to 30,000 CFM airflow @ 20" WG pressure - Choice | | | | tolerances. |
| of backward inclined, airfoil and backward curve wheel | | | | Three different wheel designs on SQB Square Fans |
| - Four discharge configurations - Narrow-width design | | | | provide the widest choice in applications suitability, |
| permits higher speed and pressures | | | | efficiency, sound, and cost. All of them feature the |
| The following accessories are avilable: | | | | backward inlcinged non overloading horsepower |
| * Clean-out door - available as a quick opening latch | | | | chracteristic, where the horse power curve reaches a |
| type door that swings open on hinges after cam | | | | peak and then decreases even as air flow increases. |
| levers have been turned, or flash bolted type with | | | | This feature allows maximum brake horsepower |
| closely spaced studs to keep door securely sealed | | | | calculation and motor selection that prevents electrical |
| with Neoprene foam tape gasketing * Shaft seals or | | | | system overloading even if system pressure changes. |
| Teflon shaft hole closures * Outlet damper - single or | | | | True aerodynamic airfoil blade shape allows stable |
| multi blade, parallel blade or opposite blade designs, | | | | operation from wide open to closed off; ideal for clean |
| manually operated or complete with mounted electric | | | | iar applications such as building ventilation with variable |
| or pneumatic actoator, for on / off or modulating air | | | | air volume system control or clean industrial gas |
| flow control * Inlet screen * Base rails with | | | | handling. Aerodynamic single surface blade shape of |
| rubber-in-shear or spring type vibration isolators * Inlet | | | | backward curve wheel offers alternative selction |
| volume control with variable inlet vanes - external or | | | | points to the Airfoil wheel and also provides stable |
| nested in the inlet cone, for manual or automatic air | | | | operation from wide open to closed-off. Flat, single |
| flow control * Housing drain - tank flange furnished in | | | | thickness backwardly inlined plades are suited for |
| scroll of fans with down blast discharge, half couplings | | | | applications from clean air to those where dust and |
| in housing drive side on all other discharges * Spark | | | | limited material is present in the airstream and where |
| resistant and explosion proof construction * Safety | | | | airfoil shapes are not recommended due to material |
| drive guards * Extended grease tube fitting * High | | | | build up that closes unbalance and vibration. |
