BioSafe Product Documents
The Drain Foam Attachment is designed to deliver complete sanitation by pushing foam through drains, ensuring 360-degree contact along pipe walls for maximum coverage. Built with durable stainless steel construction, it features a foam disc that covers drains up to 12 inches in diameter and a rubber stopper that plugs drains ranging from 3.5 to 5 inches.
What does the Drain Foaming Attachment do?
The Drain Foaming Attachment connects to any BioFoamer system to push foam directly through floor drains and into drain lines - delivering 360-degree contact along pipe walls where standard surface foaming cannot reach. The foam disc covers drain openings up to 12 inches; the rubber stopper plugs drain openings 3.5 to 5 inches during treatment to maintain foam pressure through the pipe.
Why treat drains separately from surfaces?
Drains collect organic matter, biofilm, and pathogens that surface applications don't reach. An untreated drain in an otherwise sanitized room is a pathogen reservoir that can re-contaminate the environment. The drain attachment closes that gap without requiring a separate chemical treatment or process.
