The DA 50 Air Supply Unit is an air inlet, which combines high output with low air velocity in the area occupied by the birds. DA 50-650 performs up to 12,250 m /h at 40 Pa negative pressure. The high output is obtained without the use of a fan.
Check that all ordered parts are present and intact according to the delivery note before you start your work. This chapter concerns the general mounting of the DA 50-650 unit, regardless of the type of building in which it is to be mounted.
