NEF Agricultural Packaged Fan
NEF series of agricultural packaged fans manufactured by American CoolAir feature four die-formed galvanized blades securely attached to the fan hub. Fan panle is all-galvanized construction. NEF fans are also available in waferwood frame for economy applications. Sizes: 36" - 54". Airflow to 30,500 CFM. Type NEF Fans are available as standard fan packages in the following configurations: MNEF – includes NEF Fan, Slope Wall Housing, Inlet Shutter & Guard; MNEFC – includes NEF Fan, Slope Wall Housing, Inlet Shutter, Guard and Cone; MNEFDD – includes NEF fan, wall housing and damper doors; NEFB Circulating fan; MNEFID – includes NEF 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 NCF and NBF fans.
Fan Shutters - Coolair offers several shutter options to meet any environmental, aesthetic, and production needs. The FES features interlocking aluminum blades with a galvanized steel frame and tie bars. The LRW is an all-aluminum shutter with interlocking blades, extruded aluminum frame, and nylon bearings. LRW-E motorized air inlet shutter is same as LRW with the addition of a motor kit. The PVCA features the durability and flexibility of PVC in an economical and efficient design.
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.
