1 Product description
DA 60-820 is an air intake that combines high output with low air speed in the animal zone.
DA 60-820 performs up to 16200 m
3
/h at 40 Pa negative pressure. The high output is created without using a
fan. The output is regulated steplessly via the a parallel motion system which makes sure that the unit opens
uniformly all the way round the unit to ensure uniform distribution of air throughout the house. When installing an
air diffusion fan, an equal pressure system with an output up to 25800 m
3
/h at 0 Pa per unit is achieved.
The DA 60-820 is equipped with a recirculation fan that ensures the required air jet range, even though the
amount of inbound air is reduced.
The system can be set to the air jet range required for the current time of year. In this way it is always possible
to create a combination of negative pressure and opening that provides the desired relation between output and
air speed.
