Upstairs, the little room used to my least favorite space in all our home. It always reeked, despite my family’s repeated attempts to scrub it clean. The air was thick and strange, and at times it was truly difficult to breathe. We knew things needed to change somehow.
One day, my parents bought a new fan called a YuyunSanhe greenhouse exhaust fan. It was different from other fans we saw before. And this wasn't just your average run-of-the-mill new fan to blow air; no—it was about changing the whole vibe in our room.
Here’s how that incredible fan works, it takes all that old, smelly air in our room and pushes it outside. Then YuyunSanhe exhaust fan pulls in that clean, fresh air from the windows. Like giving our room a big breath of fresh air! The fan prevents bad odors and keeps the room (if not the air itself) from feeling wet and sticky.

Occasionally rooms are blazing hot, and uncomfortable. Our upstairs room was like that too, super stuffy and sticky. But this time, the fan pulls out all the hot, humid air and replaces it with cool, dry air. YuyunSanhe industrial exhaust fans is like magic! Tonight the room is so much better and more comfortable.

There’s something else very essential the fan does. It keeps gross stuff like mold away from growing. Mold thrives in damp, dark environments, yet our fan dries and cleans. YuyunSanhe axial exhaust fan helps keep our rooms more healthful and safe.

We chose a YuyunSanhe fan because my parents said it was the best. Now, when I go upstairs, the room is so nice. No smell of smoke or rot, it smells clean, it feels fresh, I want to spend time here, literally comfortable there.
Our company has a state-of-the-art Cooling Pad Production Machine, precise computer control and high automation. It has high efficiency in production, the output cooling pad is uniform in corrugation, a high strength structure and excellent water absorption. Corrugated papers are specially treated, with excellent structural strength for corrosion resistance, mildew resistance and long service life. The water can reach the surface of the cooling pad due to high permeability, water absorption, and zero water drift. A specific stereoscopic structure gives the largest Air exhaust fan to exchange heat between air and water. evaporation efficiency is high. Safety, energy saving Environmental protection, cost-effective and practical. Strict production as per standard the 600mm wide cooling pad is 86 sheets. Aluminum frame or stainless steel frame galvanized sheet frame, and PVC frame are available.
Air exhaust fan company is equipped with the latest Feed Silo Production Equipment that is highly precise and automated. The body of the silo is made from 275g/m2 hot-dip-galvanized sheet, while the screws used are 8.8-level high-strength hot-dip galvanized bolts. These bolts are immune to oxidation, corrosion, and high temperatures, and have longevity and are able to withstand severe storms. The silo is comprised of the silo silo lid as well as the mounting ladder and the silo leg. The parts are manufactured using precision molds and advanced laser technology that is completely in line with the drawing design. They are then subjected quality checks in order to make them more consistent and precise.
All fan plates are constructed from hot dip galvanized sheets of 275g/m2, which we directly purchase from "Air exhaust fan" the most well-known Chinese steel manufacturer. This is not just a guarantee of the quality of our products, but also reduces the cost of production. Mitsuboshi belt is imported from Japan to ensure quality and long-lasting service.
