Key benefits Dualmaterial construction for durability and flexibility: a stainless steel body with CNC engraved antislip stripes plus an active silicone sleeve that adapts to various pipe diameters for straightforward and secure installation. Triple antibackflow protection: an automatic oneway flap prevents sewage backflow, keeps insects out, and helps minimize odors when the drain is not in use. flow drainage performance: a large 75 mm diameter channel increases drainage capacity by 50%, enabling substantial wastewater handling with reduced risk of clogging. Spacesaving flat design: lowprofile seal installs in tight spaces, addressing issues caused by traditional protruding floor drains and making better use of floor area. What makes it stand out Durable stainless steel body with a wearresistant surface and CNC engraved antislip stripes for secure handling during installation and maintenance. Flexible, adaptable silicone sleeve ensures a tight fit across a range of pipe diameters without special adapters. Combines strong backflow prevention with flow capacity in a compact, lowprofile form factor. Specifications Material: Stainless steel body; active silicone sleeve; CNC engraved antislip stripes. Antibackflow system: Automatic oneway flap for backflow prevention. Drainage channel diameter: 75 mm. Performance: Increases drainage volume by approximately 50%. Fitment: Silicone sleeve adapts to various pipe diameters for easy installation. Design: Flat, spacesaving form suitable for tight installations. Use scenarios Residential bathroom or laundry room floor drain: installs in tight spaces to prevent sewer backflow, deter pests, and reduce odors while maintaining drainage capability during peak use. Basement or utility room floor drain: effective where backflow and odor control are priorities, with reliable performance during heavy wastewater discharge. Small apartments or installations with limited clearance: flat design allows installation behind appliances or in cramped areas without protruding fixtures, preserving usable floor space.
