Fans

Centrifugal

3600 RPM centrifugal fans range from 5 horsepower to 200 horsepower and deliver a high amount of CFM at relatively high static pressure levels. The centrifugal fan is designed with a backward-incline wheel that is non-overloading and energy efficient. 


1800 RPM centrifugal fans range from 7-1/2 horsepower to 100 horsepower and deliver a high amount of CFM at relatively low static pressure levels. Also designed with a backward-inclined wheel for maximum energy efficiency and non-overloading characteristics. The lower rotations per minute result in a lower decibel level for grain storage close to residential areas.

Tubeaxial

Ideal for ground pile applications, our tubeaxial fans, ranging from 3/4 horsepower to 10 horsepower, are designed to deliver maximum airflow to grain structures with relatively low static pressure levels. Fans can be installed for updraft or downdraft aeration systems depending upon the customer's request.

Roof Exhaust

We manufacture a full line of roof exhaust fans for updraft aeration systems. Fan sizing and style are dependent on CFM performance and available for all different types of storage facilities. 

Vertical Mount End Wall Fans

Tiernan manufactures a 48" diameter, 5 horsepower, 1160 RPM, direct drive, end wall fan with shutters for the gable of your barn storage.


All fans are assembled and tested to ensure maximum efficiency before being shipped.
