NBC Farm Building Ventilation Fan
NBC series Farm Building Ventilation fan manufactured by American Coolair Farm Products Division feature innovative drive assembly which applies power through V-belts directly to the propeller. Blade load is concentrated directly over the bearings for more economical operation and longer bearing life. Performance and efficiency are the keynotes to the Coolair NBC Fans. Typical applications for NBC farm building ventilation fans involve confinement rearing of poultry, hogs and other livestock.
NBC series fans feature three high efficiency airfoil blades securely attached to the fan hub. Fan panle is all-galvanized construction. NBC fans are also available in Wafer Wood frame for economy applications. Sizes: 36", 48" and 52" and 54". Airflow to 50,500 CFM. Type NBC fans are available as standard fan packages in the following configurations: NBC Circulator Fan, NBCWW Circulator Fan in Wafer Wood Frame, MNBC fan package includes NBC Fan with Slope Wall Housing, Aluminum Inlet Shutter & Guard, MNBCC fan package includes NBC Fan with Slope Wall Housing, Aluminum Inlet Shutter, Cone & Guard, MNBCID-SQ fan package includes NBC Fan, Square Wall Housing, Inlet Damper, Discharge Cone & Guards. Standard fan accessories are:
SWH - Slope Wall Housing - The slope wall housing allows the shutter to be placed on the intake side of the fan and eliminates the air turbulence that occurs with the shutter on the exhaust side of the fan. It also prevents the warm air from being lost through the metal wall housing to the outside cold air in cold climate conditions. The SWH housing is constructed of galvanized steel for long, durable wear and low maintenance.
SWHCW - Slope Wall Housing with Discharge Cone - The addition of a discharge cone to the slope wall housing greatly increases the performance of the fan for a minimal initial investment. American Coolair’s discharge cones are specifically engineered to recover energy from the air stream, converting it into increased airflow (as much as 12%), while at the same time, reducing electrical power consumption. Cones are galvanized steel and come with a concentric wire guard.
FWH - Square Wall Housing - Coolair’s FWH wall housing is an exterior unit to house any Coolair fan and the LRW shutter. The FWH is constructed of heavy gauge galvanized steel and can be attached to exterior walls to free the interior space from obstructions.
Housing Guards - Fan housings come standard with galvanized mesh guards with 2” spacing. Slope wall housings have a front guard, while the square wall housings have a rear guard. For housings where OSHA guarding is necessary, PVC coated steel wire guards with 1/2” x 1” spacing are available. Shutter-side guards are also available.
Pivot Fan Mount - For precision air circulation, Coolair offers its Pivot Fan Mount. The mount consists of galvanized steel tubing, and the fan is held in place utilizing heavy gauge painted steel mounting brackets. The mount can be affixed to any structural column in the building, and with full 2-axis adjustment, the fan can be positioned to deliver air anywhere in the house. The Pivot Mount is available for all NBC fans.
DD - Damper Door Cone - The DD Damper Door Cone functions as both a damper and discharge cone. The galvanized damper doors open fully when the fan is energized, removing virtually all blockage from the airstream. When the fan is powered off, the doors automatically close and seal magnetically. Gasketing around the circumference of the doors provides a complete weather barrier.
IDD - Inlet Damper Door - They can be used in place of a standard inlet shutter, for increased fan performance. It also isolates the fan motor and drives from the corrosive in-house atmosphere. The IDD can be specified with a new fan, or as a shutter replacement on existing installations. The IDD can also be insulated to save on energy costs.
