DA 1540 Ceiling Inlet

Product overview：

The ceiling inlet is an efficient, compact inlet for attic constructions that directs fresh air into the livestock house through the attic space. The ceiling inlet design ensures optimum regulation of air volume, air velocity, and air direction relative to the temperature and layout of the house. The velocity of the required incoming air volume is low during cold periods.During hot periods with high ventilation requirements, the inlets can be fully opened, directing the air to where the animals are.The ceiling inlet is designed to create maximum air velocity during hot periods.

The DA 1540 is an efficient, compact fresh air inlet for ceiling constructions. The inlet opens by pulling the cord.
The ceiling inlet is made of dirt-repellent, easy-to-clean, injection-moulded PS, PA and POM.
The inlet is delivered fully assembled. The ceiling inlet consists of an inlet casing, a draw hook with a cord, and
an inlet flap.
The ceiling inlet is available in the following variants:
• DA 1540 ceiling inlet
• DA 1540 HP ceiling inlet
• DA 1540 chill inlet
DA 1540 ceiling inlet is used when the ceiling is flat, while DA 1540 HP ceiling inlet has more powerful springs,
so it can be used for ceiling pitches up to 15°. DA 1540 ceiling inlet and DA 1540 HP ceiling inlet can be used
with advanced inlet control.
DA 1540 chill inlet has the special feature that it can open up to 105° degrees and thus direct the air vertically
down the pen. When the inlet is placed near the wall, it can thus create a “chill” effect in the area occupied by
the animals when maximum cooling is required.
