Sanitary Fan Manway Cover

Sanitary sector manhole, also known as fan-shaped manhole, is a special hygienic access opening tailored for tank top and corner installation positions. With a unique fan-shaped structure, it perfectly fits the arc and corner dead space of tank equipment, making up for the installation limitations of round and square manholes. Made of high-quality stainless steel with seamless mirror polishing, the manhole features smooth surface, no sanitary dead corners, and easy cleaning and sterilization. The reliable locking and sealing structure ensures excellent tightness, adapting to normal pressure and low-pressure hygienic production environments. It is widely used for daily inspection, cleaning, maintenance and sampling of various sanitary storage tanks and fermentation equipment.
