Cleanroom Drainage, Hygiene and Safety Equipment
Trapped Cleanroom Floor Drain
Compact cleanroom drain with a removable water-seal trap to control sewer gases while retaining service access.
- Removable Water-Seal Trap
- Cleanable Stainless Seal Cup
- Above-Floor Service Access
- Vertical or Side Outlet
Product Introduction
The trapped cleanroom floor drain integrates an accessible water-seal cup below a flush stainless top. Its welded body and removable internals allow the trap, basket and sump to be inspected from above without opening the connected drain line. Vertical and side-outlet versions suit different slab depths, while the floor flange can be configured for resin, vinyl or tiled finishes.
Key Features
The smooth stainless sump and seal components can be lifted out for cleaning.
An optional sediment basket protects the trap and downstream pipe from larger debris.
Vertical or horizontal discharge arrangements accommodate different floor constructions.
Customer Product Concerns
Intermittently wet controlled rooms need odor isolation without creating a concealed trap that is difficult to inspect, prime or clear.
An untrapped floor opening can allow drainage odors to enter a controlled room.A removable water-seal cup creates a physical barrier between the room and waste pipe.
Long idle periods can allow the water seal to evaporate.An optional trap-primer connection can replenish the seal where the maintenance plan requires it.
A blockage below a fixed grate may require disruptive pipe access.The grate, basket and trap cup remove from above so the outlet can be cleared directly.
Deep traps may conflict with shallow slabs or congested services.Selectable trap depth and vertical or side outlet layouts adapt the body to available floor depth.
Typical Applications
Cleanroom gowning areasControlled laboratoriesSanitary roomsIntermittent-wash support spaces
