Natural care with fresh air
The 71 cm fan generates fresh air around your animals, to prevent heat stress. It can be installed in the holding area, along the feeding tables, over the cubicle side rows in big barns and in barns with low inner height. The installation angle is 19° to 21° along a feeding table or over a cubicle, with six to eight meters between each fan for an optimal ventilation pattern. In a holding area the fan should be installed at an angle of 15° to 30°. The protection grill is tight enough to put the fan below 2.7 m. The number of rows and fans needed in the building depends on its density, construction, utilization and local climatic conditions.
16400 m³/h of air is projected and the speed is automatically adjustable to suit your temperature settings via a control box. For security reasons, the DeLaval DF710 is provided with a protective cage on each side.
