Tunnel Air Inlets for Poultry Houses – WUSEN

WUSEN air inlets feature a standard modular design that allows for direct installation into wall openings without requiring structural modifications. Multiple units can be combined to fit end-wall installations of various widths. This flexibility makes them an ideal solution for locations with limited wall space—particularly in caged poultry houses where installation room is restricted. With an opening height of just 35 cm when fully open, they maximize airflow even in compact spaces.

In poultry houses utilizing tunnel ventilation, air travels at high speed from one end to the other, making the design of the air inlet critical. WUSEN tunnel air inlets are specifically engineered for this purpose, combining precise control, durability, and energy efficiency.

The WUSEN ventilation system is directly driven by electric linear actuators, enabling stepless adjustment of the opening from 0% to 100%. With a response time of under 10 seconds, the system reacts rapidly to environmental changes. It integrates seamlessly with WUSEN environmental controllers to provide fully automated, coordinated control of temperature, air speed, and negative pressure, maintaining a stable environment without the need for frequent manual intervention.

Constructed from UV-resistant, ammonia-resistant, and moisture-proof engineering plastics, the air inlets are exceptionally durable. This design minimizes maintenance requirements and ensures a long service life, representing a reliable, long-term investment for your farm.

Airflow Guidance: Preventing Stress

Preventing stress is at the core of WUSEN’s design philosophy. Specially angled louvers direct high-speed airflow toward the upper part of the poultry house, creating the “Coandă effect.” This allows cold air to mix thoroughly with the warm air near the ceiling before settling. This process eliminates the risk of cold drafts and reduces the likelihood of respiratory diseases, ensuring the birds maintain optimal performance in a comfortable environment.

Energy efficiency is a top priority. The air inlet features a multi-louver design equipped with double-layer rubber seals; when closed, it achieves a complete seal with an air leakage rate of less than 1%. In winter minimum ventilation mode, heat loss is minimized; energy savings of up to 30% are achieved compared to standard curtains or wall openings. This precise control capability is crucial for maintaining optimal indoor temperatures during cold weather.
