Pure Copper EC Motor & Maintenance-Free Design
This factory exhaust fan uses a 100% pure copper EC motor, supporting stable 24/7 continuous operation with low heat and low power loss. The belt-free direct drive structure avoids slipping, aging and frequent replacement, greatly reducing later maintenance costs. Coaxial transmission ensures zero energy loss, constant speed and non-decaying airflow, achieving long-term energy-saving and maintenance-free performance.
Dual Material & Full Sizes for Factory Exhaust Fan
We provide two mainstream housing materials for factory exhaust fans. Galvanized steel fans are sturdy and cost-effective for general manufacturing workshops. Fiberglass fans feature acid and alkali resistance, rust-proof and aging-resistant performance for chemical plants and livestock farms. Sizes cover 24–50 inches to fit small spaces and large factory ventilation demands.

Factory Exhaust Fan Solutions for Diverse Application Scenarios
Our factory exhaust fans deliver real high airflow to blow away heat, dust and odors in workshops and warehouses. Every fan is tested in a wind tunnel lab with no fake airflow data. It solves common problems like sweltering workshops, low efficiency and frequent staff complaints. The energy-saving EC motor runs 24/7 and greatly cuts your electricity bills. It operates steadily with low vibration and low noise, helping you avoid noise complaints, fines and failed environmental inspections. Your team works in a better environment, and your production runs more smoothly.
Are you troubled by high humidity, heavy ammonia odors, and short fan service life on your farm? Our factory exhaust fan is built for harsh breeding environments. It delivers strong airflow to cool down the barn quickly and remove ammonia and excess moisture. The corrosion-resistant body never rusts easily, and the IP66 waterproof motor resists burnout during daily washing and disinfection. Stable ventilation reduces livestock heatstroke and disease, helping you cut breeding costs and gain better profits.
Ordinary fans corrode fast and fail easily in corrosive chemical and spraying workshops. Our anti-corrosion factory exhaust fan adopts acid and alkali resistant fiberglass material. It quickly exhausts harmful smoke, waste gas and pungent odors, stops dust leakage, and helps you pass environmental inspections smoothly. With optional anti-static design, it perfectly fits all your high-risk industrial working conditions.
As a project contractor, you’ve probably dealt with inaccurate specs, uneven quality and late shipments that put your payments at risk. Our factory exhaust fans are built to consistent standards, so quality stays reliable across every unit. We help you choose the right model based on your actual site conditions, so you won’t face rework from poor airflow. With strong production capacity and on-time delivery, we keep your project on schedule. We also offer full customization and complete certification documents to make project approval and auditing as smooth as possible.
Poor ventilation and humid stuffy air often cause mold, bad crop growth and low yield in your greenhouses. Our factory exhaust fan fits all types of agricultural greenhouses. It provides stable ventilation and balances temperature and humidity, improves stuffy and damp conditions, and prevents mold and crop loss. Durable and low-maintenance, it optimizes your planting environment and effectively upgrades your crop quality and output.
