DA 60-820 roof inlet

Negative and equal pressure systems in livestock houses

DA 60-820 is a roof inlet for livestock houses that combines both high outputs with low airspeed.

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

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

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

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 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 draughts inside the livestock house due to the uniform openings and air distribution.
• Uniform distribution at 100% stepless regulation.
• The outlet funnel and the bottom plate are made from polyurethane with a material thickness of 30 mm to counteract condensation.
