Shut out odors and insects! Sanitary drainage manholes for hygiene management.

Eliminate the worries of hygiene management caused by stagnant water and block the growth of odors and bacteria! The balance valve of the dry trap opens due to the weight of the water and automatically drains it.

The "Sanitary Drainage Pit" automatically drains even a small amount of wastewater by opening the balance valve due to gravity, ensuring that no wastewater (standing water) remains in the pit. Once the water flow stops, the valve automatically closes, preventing the intrusion of cockroaches and mice. It can be widely installed in food processing plants, meat processing plants, plant factories, school lunch centers, supermarkets, livestock facilities, and more. Unlike traditional water-seal types, the "Sanitary Drainage Pit" does not produce odors or attract small flies due to standing water, and there is no slime or clogging. Customers will notice the difference when they use it. 【Features】 ■ Blocks bacteria and odors with a dry trap. ■ Easy maintenance and long-lasting cleanliness. ■ Heavy-duty grating installation allows for the passage of cart forks. ■ Compatible with various pit shapes and allows for cleaning with mesh baskets. *For more details, please refer to the PDF document or feel free to contact us.
