Sealed Light Proof Exhaust Fan

Product Overview

Specially designed for tunnel-ventilated poultry houses, livestock facilities, and commercial greenhouses. Features tight-sealing front double doors to effectively block external light penetration and severe weather conditions while delivering high-volume airflow.

Key Features & Selling Points

• Light-Proof & Weather-Sealed Design: Front double doors fit tightly when inactive, blocking external light to maintain proper lighting control inside dark-out poultry houses while preventing rain, wind drafts, and pests from entering.

• High Static Pressure & Airflow: Engineered for high negative pressure conditions, delivering high-volume air exchange to rapidly clear heat, humidity, dust, and harmful gases (ammonia and hydrogen sulfide).

• Heavy-Duty Anti-Corrosion Build: Constructed from high-strength galvanized steel or fiberglass housing with durable stainless steel/galvanized blades, built to withstand high-humidity and high-ammonia environments.

• Energy-Efficient Performance: High-efficiency motor paired with aerodynamically optimized fan blades ensures maximum ventilation output with low power consumption.

• Smooth & Low-Noise Operation: Precision-balanced blades and heavy-duty bearing system reduce vibration and noise, minimizing stress on poultry and animals.

Applications

• Poultry & Livestock Housing: Broiler houses, layer farms, duck houses, swine housing, and dairy cattle barns.

• Agricultural Greenhouses: Commercial greenhouses needing precise light deprivation and high-volume climate control.

• Industrial Facilities: High-humidity workshops, chemical warehouses, and processing plants requiring heavy-duty exhaust systems.
