New Publication Helps Farmers Select Energy Efficient Fans

Efficient fans are essential for proper ventilation of poultry production facilities. A new publication from Iowa State University Extension explains the factors farmers should consider to address energy efficiency when selecting or upgrading fans.

Efficient fans are essential for proper ventilation of poultry production facilities. A new publication from Iowa State University Extension explains the factors poultry farmers should consider to address energy efficiency when selecting or upgrading fans.

"Energy Efficient Fans for Poultry Production," PM 2089H, is available to download from ISU's Extension Online Store at www.extension.iastate.edu/store.

This publication addresses considerations when selecting a fan, such as air delivery, static pressure, fan efficiency and ratings by independent laboratories. It also describes factors that affect fan performance.

"Fans serve as the engine of the ventilation system and they are critical to bird health and performance," says Jay Harmon, ISU professor of ag and biosystems engineering. "Larger fans are typically more efficient than smaller ones, but just because two fans are equal in size doesn't mean they are equally efficient. When you're comparing different fan manufacturers, look for independent test data."

How are various ventilation fans rated for energy efficiency?

"If you're upgrading your ventilation or building a new facility, talk to your local utility provider," says Dana Petersen, ISU Extension program coordinator. "There may be rebates available for new equipment, but fan efficiency ratings are often used to determine rebate eligibility."

The new ISU publication is part of a series of farm energy conservation and efficiency educational materials being developed through the Farm Energy Conservation and Efficiency educational initiative. The purpose of the initiative is to increase farmers' awareness of farm energy conservation practices.

Sponsored by a grant from the Iowa Energy Center, the program is also helping farmers explore alternatives to reduce farm energy demand and to improve their farms' overall profitability in a rapidly changing energy environment. To find other publications in the series, go to the ISU Extension Online Store, www.extension.iastate.edu/store, and search for farm energy.
