The air delivery performance and energy efficiency of a number of commercially available ventilation fans have been measured with a fan test chamber. The air distribution and air velocity profile of the most common swine facility ventilation inlet (continuous slot with adjustable baffle) has also been measured. This information will enable swine producers and building designers to select ventilation systems based on documented performance under realistic operating conditions. Since the availability of this information will allow customers to make informed decisions when purchasing ventilation equipment, it will also encourage the ventilation equipment industry to develop design improvements in order to stay competitive.
