Poultry ventilation systems

A crucial component for chicken farming – the side wall air inlet.

Whether you raise broilers or laying hens, whether it’s a large-scale commercial farm or a small breeding farm, the environmental quality of the chicken coop directly determines the health of the chickens, production efficiency, and ultimately, your profits. Among all ventilation solutions, the side wall air inlet is arguably both a core and cost-effective element.

So why is it so important? First, it provides uniform fresh air to meet the high oxygen requirements of chickens.

Many people may not know that chickens have exceptionally high oxygen requirements. For example, broilers consume twice the oxygen of mammals of the same weight, and their metabolism is extremely fast. Chickens produce large amounts of carbon dioxide and ammonia during respiration and excretion. In enclosed or high-density chicken houses, poor ventilation can lead to the accumulation of stale air and insufficient oxygen. Chickens suffering from oxygen deficiency will experience difficulty breathing, reduced feed conversion rates, and in severe cases, suffocation. This problem is particularly pronounced in common large, enclosed chicken houses.

So how do side-wall air inlets solve this problem?

They are typically installed evenly on the upper part of both side walls of the chicken house, working in conjunction with negative pressure fans to continuously draw in fresh, clean air from outside, creating a balanced horizontal airflow circulation. Unlike centralized air intake systems, side-wall air inlets ensure that fresh air is delivered from front to back and from top to bottom to every corner of the chicken house. Furthermore, they can precisely control the amount and speed of air intake based on the breed, density, and growth stage of the chickens—generally, the optimal wind speed is 4.7 meters per second, and the negative pressure is around 16.3 Pa, achieving the best ventilation effect. In this way, the chickens’ oxygen needs are fully met, their metabolism and growth are normal, and their survival rate and production performance naturally improve.
