DA 60-820 roof inlet

Negative and equal pressure systems in livestock houses

The DA 60-820 is a roof inlet combining high outputs and low airspeed for livestock houses.

Negative pressure occurs when fresh air is pulled in from outside through the inlets.

High output in livestock houses is created without using a fan. The output is regulated steplessly via a parallel motion system that ensures uniform unit opening and uniform air distribution throughout the house.

When an air-diffusing fan is installed, you can use the DA 60-820 for equal-pressure systems.

You can equip the DA 60-820 with a recirculation fan (optional) that maintains the required air-jet range, even when 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 airspeed.

Features and benefits:

• Uniform climate all year round.
• Provides high air output with low airspeed (performs up to 16,200 m³/h at 40 Pa negative pressure).
• No drafts inside the livestock house due to the uniform openings and air distribution.
• Uniform distribution at 100% stepless regulation.
• To counteract condensation, the outlet funnel and the bottom plate are made from polyurethane with a 30 mm thickness.
