VENTILATING FANS (FC):
Fan Equipment’s ventilating fans are designed for applications requiring higher volume and lower noise output.

Forward Curve Fans – FC Ventilating Fans

Wheel Blade Type: single thickness forward curved

19 sizes each line (FCS & FCD): 12” thru 73” wheel diameters

Pressures: to 6” W.G. (FCS & FCD)

Temperatures: to 1000°F (FCS), up to 120°F (FCD)

Performance Type: high volume with low static pressure

Construction: AMCA Classes I, II & III as well as our extreme Class IV.

Typical uses: Commercial HVAC, Refrigeration, Plug Fans for Oven Recirculation, Heater Boxes, Cabinet Fans.

Type FC fans provide high volume (CFM) at much slower running speeds than our Type BC and are used for all types of Air Handling applications requiring low noise output and long service life. Type FCS fans are SISW (Single Inlet, Single Width) while FCD fans are DIDW (Double Inlet, Double Width). These Ventilation Fans are typically used to supply or exhaust clean and should never be used in a dirty\dusty environment as the curved blades will experience build-up very quickly leading to imbalance issues.

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 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 1000°F, FCS only), corrosive airstreams, spark-resistance, and low leakage applications. Optional materials of construction include various Stainless Steels, Inconel, Hastelloy, AL6XN, Monel, Titanium, Aluminum, FRP (Fiberglass Reinforced Plastic) (housings only) and more.

Standard finish is gray enamel. We offer numerous paint and coating options on both the airstream and exterior surfaces.

Type FC are not for any level of material, dust, or particulate handling. For material handling capabilities refer to our BISC or M-IE Industrial Line.
