Overview
What is a tunnel ventilation system for poultry houses?
Tunnel ventilation moves air the house length through wall fans, with evaporative pads at the inlet and light traps on dark-out houses at the fan openings.
Overview
5090 vs 6090 vs 7090 pad grades overview
5090, 6090, 7090, and 7060 are cellulose pad grades on this site. Thickness options on the cooling-pads page are 100 mm, 150 mm, and 200 mm.
Overview
Why do dark-out poultry houses need light traps?
Dark-out houses run lighting programs; daylight at fan openings would break them. Light traps pass air and block daylight at the exhaust-fan wall.
Sizing
How many exhaust fans does a tunnel-ventilated poultry house need?
Size tunnel fans from the house cross-section and target air speed, not from house length alone. Worked example, static pressure effects, and what to send for a quote.
