Installation

DS fans are supplied ready for automatic operation with installation only requiring mounting and connection to a single phase electrical supply.

Standard units are supplied with an integral thermostat to operate the fan as soon as the roof space temperature rises above the set point.

For frost protection applications units are  supplied without thermostats to be linked to frost protection controls.

The four-way adjustable outlet blades allow the air direction and terminal velocity to be set to suit the application and mounting height.

Design Data

Select the DS unit to suit the mounting height required, ideally the units should be installed  approximately 1 metre below the apex.

Calculate the volume of the building and multiply by two to determine the amount of air that needs to be re-circulated for effective de-stratifi cation. Divide by the primary air volume of the unit to determine the number of units required.
