TYPE NBF FAN
ECONOMICAL, PRACTICAL, EFFECTIVE

American Coolair's Type fan provides the solution to fresh air ventilation in most types of farm  buildings. Type NBF fans are built to give you years of heavy-duty trouble free service. The rugged, belt driven construction operates in any position, and is available with single or two speed totally enclosed motors. Coolair has developed a complete ventilation system for farm use combining the type NBF fan with all aluminium shutter (type LRW) and heavy gauge galvanized steel wall housing (square box or slope) for exterior mounting, allowing a maximum of unobstructed interior space.  

EXCLUSIVE DRIVE ASSEMBLY

Our engineering department  has developed an innovative drive assembly for the Type NBF fan. Our use of quality materials and precise engineering techniques in constructing wheel assemblies assures you of years of quiet, trouble free service. Power is applied through V-belts directly to the propeller with blade load concentrated directly over the bearings to eliminate overhang bearing load. This exclusive, time tested design has been widely acclaimed by engineers and users.

BASIC COMPONENTS

PERFORMANCE AND EFFICIENCY

Coolair's engineers have designed a most successful combination of blade and flared orifice resulting in efficient operation.

CONTROLLED ENVIRONMENT SYSTEMS
COOLAIR POWER TUBE FAN

In controlled environments where a precise tempering of air is critical to production, American Coolair offers the Power Tube Fan. 
Coolair Power Tube Fans are especially designed units developed for compatibility with polyethylene tubes. For the necessary low velocity tempering of air, these fans and tubes are perfectly matched. 

Constructed of heavy gauge steel, the Coolair Power Tube Fan is offered in diameters of 12, 18, 24 and 30 inches. The 12 and 18 inch fans are direct drive units. The 24 and 30 inch fans are belt driven and incorporate the Coolair exclusive stationary shaft design from the Coolair NBF type units. Belt drive models have two sealed lifetime lubricated oversized shaft bearings. The propellers have six steel die formed blades. All Power Tube fans employ air straightener vanes for efficient air distribution. 

All Coolair motors are of heavy duty type, totally enclosed, for fan operation. They employ sealed ball bearings for continuous trouble free performance. Manufactured from polyethylene tubing, the Power Tube is custom punched to suit your particular requirements. The Power Tube is clear so as not to totally obscure vision in your facility. 

The new Coolair Power Tube Hangers slide easily into position on the tubing. They are easily installed by clipping each on a suspended wire. The Tube Hanger supports the tube when not in use. This feature allows for both additional unrestricted view and normal air movement as well. 

The Coolair Power Tube is a methodically researched product...designed to meet the ventilation needs of the industry with traditional American Coolair quality.

Performance shown for PTF Fans is with Polyethylene Discharge Ducts attached. 1Brake Horsepower listed include drive losses.
