PRODUCT DESCRIPTION
The DA 60 air supply unit is an air intake that combines high output with low air velocity for the animals'
occupational zone.
The DA 60-920 supplies up to 20,000 m3/h at 40 Pa negative pressure. The high output is obtained without
using fans.
The DA 60 has a parallel motion system which makes sure that the air supply unit opens uniformly round the
unit to ensure uniform distribution of air throughout the house.
The unit can be adjusted to the air jet range desired for the current time of year. It is in this way possible to
always create a combination of negative pressure and opening which gives the desired relation between output
and air velocity.
The DA 60 air supply unit is moulded in PUR with high insulation capacity and the metal parts are made from
stainless steel A2.
