Home Climate Solutions Poultry Ventilation Side ventilation

Key consideration for side ventilation system:

Poultry-temperature-608

Cold or mild climate

Side ventilation is essential in regions where full tunnel ventilation isn’t practical year-round. The choice of air inlet system must align with external air temperature, flock size, and barn type.

Poultry-farm-icon-608

Essential for Brooding & Rearing

In early life stages, chicks are sensitive to drafts and temperature shifts. Side ventilation ensures even, gentle airflow that supports warmth, welfare, and uniform growth.

Efficient Airflow, Lower Energy Costs

When combined with E-line fans, side ventilation minimizes electricity, fuel use, and noise — while maintaining consistent indoor air quality.

Precision application for broiler and layer

Side ventilation is critical during cold seasons or as a transition strategy between minimum and tunnel ventilation modes. It’s especially effective for:

  • Gentle air renewal
    Draft-free, ceiling-directed airflow supports chick comfort and survival in early brooding.
  • Energy savings
    Precise airflow minimizes heating and ventilation costs, without sacrificing air quality.
  • Dryer litter, better hygiene
    Proper air mixing prevents wet spots and reduces ammonia build-up, improving leg health and air quality.
  • Smooth climate transitions
    During spring and fall, transition ventilation bridges the gap between cold- and warm-season strategies — with airflow capacity and control being critical.

Product selection matters 

Sidewall inlets must match your barn design (cage, aviary, or floor systems) to achieve proper air distribution.

  • Solutions for Aviary Systems
    Special inlets with sliding doors help prevent birds from perching on flaps and reduce crowding.
  • Enhanced airflow in tight spaces
    When space above cages is limited, our air deflectors improve airflow and Coanda effect — ensuring even air mixing.
  • Optional light filters and canopies
    For light control and biosecurity, we offer customizable accessories for your inlet setup.

FAQ

Find answers to the most common inquiries about side ventilation, system performance, and how to choose the right solution for your farm.

How does side ventilation work in poultry houses?

Side ventilation draws fresh air through sidewall inlets, directing it across the ceiling where it mixes with warm air before reaching the birds. It ensures controlled airflow, fresh air exchange, and temperature stability—especially in cooler weather or during brooding.

When should I use side ventilation versus tunnel ventilation?

Use side ventilation during cold or mild weather, or for young birds needing stable, gentle airflow. Switch to tunnel ventilation in hot weather for maximum cooling. Many farms use both in a combi-tunnel system for year-round efficiency.

What are the fan and inlet requirements for proper side ventilation?

You need enough fans to achieve minimum ventilation rates based on bird age and density, and properly sized inlets to control air speed and direction. A well-sealed house is critical to ensure fresh air reaches the center and avoids drafts.

What maintenance is needed for sidewall inlets and fans?

Regularly inspect inlets for dust buildup or mechanical wear. Clean fans and shutters to maintain airflow efficiency. Check actuator function and static pressure levels to ensure inlets open and close as intended.

How do I calculate the minimum ventilation rate using side ventilation?

Minimum ventilation is calculated based on bird weight, age, and house volume, and bird genetics. Consult our ventilation expert for an accurate design.

Can I retrofit side ventilation into an existing poultry house?

Yes, many older houses can be upgraded with side inlets and proper fan systems. Success depends on the house’s airtightness, insulation, and structural layout. A professional evaluation is recommended to ensure effective airflow and climate control.
