800mm Wall Mount Drop Hammer Negative Pressure Ventilation Exhaust Fan

Product Overview

The 800mm Wall Mount Drop Hammer Negative Pressure Ventilation Exhaust Fan is a compact, high-efficiency ventilation fan specifically developed for small to medium-sized livestock barns, poultry houses, and agricultural greenhouses. Featuring a hot-dip galvanized steel housing and an automatic drop hammer shutter mechanism, this 800mm fan delivers reliable negative-pressure airflow, effective heat dissipation, and long-lasting performance in humid and high-corrosion agricultural environments.

Key Features

• Compact 800mm High-Efficiency Design: Optimized dimensions ideal for space-constrained installations while providing strong negative pressure for quick air exchange.

• Corrosion-Resistant Galvanized Frame: Built with premium hot-dip galvanized steel casing and durable blades to withstand harsh farm environments and extend service life.

• Automatic Drop Hammer Shutter System: Shutters open automatically under centrifugal airflow during operation and seal tightly by gravity when turned off—preventing backdrafts, rain, dust, and insects.

• Low Noise & Low Energy Consumption: Dynamically balanced blade assembly paired with a smooth belt-driven transmission ensures whisper-quiet operation and reduced power draw.

• Cooling System Compatibility: Integrates smoothly with evaporative cooling pads to build a complete climate control system for temperature-sensitive livestock and crops.
