Frequently Asked Questions

The push pull fan system uses two fans—one to push fresh air into the space and another to pull stale air out. This creates a balanced airflow that ensures uniform ventilation and temperature control, especially effective in long buildings like poultry houses and workshops.
Animal husbandry fans must provide consistent airflow to remove heat, moisture, and ammonia while maintaining a comfortable environment. They should be durable, corrosion-resistant, and capable of operating continuously under high humidity and dust conditions.
A negative pressure fan consists of a fan blade, motor, bellmouth, shutter (often butterfly type), and a sturdy frame. It works by extracting air from inside a building, creating negative pressure that draws fresh air through inlets, ensuring continuous air exchange.
Yes, our fans and air coolers are widely used in industrial workshops for temperature control, fume removal, and air circulation. The heavy hammer fan and push pull systems are especially effective in large manufacturing and processing facilities.
Yes, we provide customized ventilation and cooling solutions based on building size, climate conditions, and specific application needs. Contact us for a tailored system design.
