Product Description
This anti‑backdraft butterfly cone fan is purpose‑built for chicken barns and commercial poultry houses, focusing on reliable sealing performance when the fan stops running. Equipped with precision‑fitted butterfly double‑door structure and full‑perimeter rubber sealing strips, the shutters close completely once the fan powers off, achieving 100% tight sealing.

It effectively blocks cold air backflow, outside light infiltration and wind reverse‑draft. Unwanted cold drafts will no longer disturb the stable indoor temperature, and light leakage is eliminated, which is critical for layer chicken farms that require strict light cycle management.
The cone‑shaped housing delivers stable negative‑pressure exhaust airflow during operation. The housing is available in hot‑dip galvanized steel or fiberglass material, resisting ammonia vapor and high humidity inside poultry facilities for long‑term service life.
Designed to pair with automatic climate control systems, this sealed cone exhaust fan is widely adopted in broiler houses, layer barns and multi‑stage poultry farming projects. It prevents temperature fluctuation caused by idle‑fan air leakage, helping you maintain consistent barn environment and improve poultry production performance.
