Type BC fans are quiet and efficient. They are used for all types of Air Handling applications requiring high efficiency, low noise output, long service life, and lower operating costs. Type BCS fans are SISW (Single Inlet, Single Width) while BCD fans are DIDW (Double Inlet, Double Width). Full width BCS and BCD fans (sizes 2 thru 12) bear the AMCA Certified Label for Air Performance. These Ventilation Fans are typically used to supply or exhaust clean air near room temperature, as well as exhausting contaminated, noxious, or hot air away from workers and/or machinery when properly specified.
Type BC fans exhibit non-overloading horsepower characteristics. This provides a BHP (Brake Horsepower) curve that reaches a peak within the normal operating zone allowing the optimum motor (or other prime driver) selection that will not overload with a drop in the system’s pressure.
The impellers are all welded high-strength steel construction with gauges and features to ensure structural integrity and long life throughout the operating class. Hubs are taper-lock or clearance straight bore depending on the application. All fans are factory balanced to ISO 1940/1 Grade G2.5 (1/10 in/sec max velocity).
The aerodynamic volute shaped housings are constructed of robust gauges for each class, are substantially braced, and have a continuously solid welded exterior scroll to the side seams. Solid welding inside and outside is available upon request.
Standard construction is for clean to mildly dirty air up to 200°F maximum temperature. Special options, materials, and construction features are available for other demanding process conditions such as elevated temperatures (up to 700°F), corrosive airstreams, spark-resistance, and low leakage applications. Optional materials of construction include A588, A656, A514, various Stainless Steels, Inconel, Hastelloy, AL6XN, Monel, Titanium, Aluminum, FRP (Fiberglass Reinforced Plastic) and more.
Standard finish is gray enamel. We offer numerous paint and coating options on both the airstream and exterior surfaces. Rubber lined housings interiors are available where practical.
While not specifically for material handling, BCS fans are capable of light dust and particulate handling but are subject to fan wheel material build-up which must be monitored. For more serious material handling capabilities refer to our BISC or M-IE Industrial Line.
