SKOV DA 60-820 Roof Inlet

High-Capacity Fresh-Air Distribution for Poultry and Livestock Ventilation

The SKOV DA 60-820 Roof Inlet is an agricultural ventilation air inlet designed to deliver high fresh-air intake capacity while maintaining low air velocity in the animal-occupied area of poultry and livestock buildings.

Designed for negative-pressure and equal-pressure ventilation systems, the DA 60-820 introduces fresh air through the roof and distributes it throughout the building. Its stepless parallel-motion regulation system allows the inlet to open uniformly, supporting balanced airflow and consistent indoor climate conditions.

The roof inlet is particularly well suited to wide agricultural buildings where distributing incoming air evenly can be challenging.

For producers looking to improve fresh-air management, the SKOV DA 60-820 Roof Inlet offers a flexible solution for compatible new construction and ventilation upgrades.

Key Features & Benefits

• High-Capacity Fresh-Air Intake: Designed to provide substantial incoming airflow without requiring an integrated intake fan in negative-pressure operation.
• Low Air Velocity at Animal Level: Helps reduce uncomfortable drafts in areas occupied by poultry and livestock.
• Uniform Air Distribution: Supports consistent fresh-air distribution throughout the building, including wider barn layouts.
• 100% Stepless Regulation: Allows continuous adjustment of inlet opening rather than relying on fixed positions.
• Parallel-Motion Opening System: Ensures uniform inlet movement and controlled airflow distribution.
• Negative-Pressure Compatibility: Suitable for ventilation systems that draw fresh air into the barn using exhaust-generated negative pressure.
• Equal-Pressure Compatibility: Can be incorporated into equal-pressure ventilation systems when equipped with an appropriate air-in fan.
• Optional Recirculation Fan: Supports the required air-jet range when incoming fresh-air volume is reduced.
• Reduced Sensitivity to Outdoor Wind: Designed to maintain dependable air distribution despite changing external wind conditions.
• Suitable for Wide Buildings: Helps address ventilation challenges in wider poultry and livestock facilities.
• Roof-Mounted Installation: Introduces fresh air through the roof rather than relying exclusively on wall-mounted air inlets.

How the SKOV DA 60-820 Roof Inlet Works

The DA 60-820 introduces outside air through a roof-mounted inlet as part of a coordinated ventilation system.

Step 1 — Fresh Air Enters Through the Roof

Outside air is drawn into the inlet by the building’s negative-pressure ventilation system or supplied through an appropriate fan arrangement in an equal-pressure system.

Step 2 — The Inlet Opening Adjusts

The parallel-motion mechanism regulates the opening continuously according to the ventilation system’s requirements.

Step 3 — Air Is Distributed Throughout the Building

The inlet’s design supports uniform fresh-air distribution while limiting excessive air velocity in the animal-occupied area.

Step 4 — Air Distribution Is Maintained at Reduced Ventilation Rates

An optional recirculation fan can help maintain the required air-jet range when fresh-air intake volume decreases.

Step 5 — The Ventilation System Maintains Climate Conditions

When integrated with appropriately designed ventilation equipment and controls, the roof inlet contributes to consistent air distribution throughout the barn.
