A wide range of SUS-made drainage channels and other products to support your operations implementing advanced hygiene management based on HACCP! We introduce drainage pits, catch basins, and pit covers.

The HACCP support drainage system "Duster Pit Series" is a stainless steel drainage fixture designed with ease of cleaning and management in mind, especially in light of the mandatory implementation and operation of HACCP since June 2021. The part that receives the grating is not flat but has a sloped shape, which prevents clogging and allows for smooth drainage. We offer a variety of products, including the "Neo Duster," which significantly reduces the labor involved in cleaning tasks. This all-stainless steel drainage system is suitable for food production environments such as food service centers, food factories, hospitals, and restaurant kitchens. 【Features】 ■ Difficult for debris to accumulate, easy to clean ■ Made entirely of stainless steel for high durability ■ Complies with hygiene standards for food factories ■ Custom product shapes can be proposed to match zoning requirements *For more details, please download the PDF or contact us directly.

Nihon Pit was established in 1968 as Japan's first independent pit specialty manufacturer, standardizing and mass-producing traditional manhole covers. Since then, we have developed many products, including general wiring and drainage pits for construction, trench ducts and OA floors for office automation, and drainage troughs, among others. Moving forward, we will continue to pursue a wide variety of specialized pits (manhole covers) that transcend the boundaries of architecture, civil engineering, and facilities, always aiming to create products that are ahead of their time.
