Could a sealing sill impede carts or wheelchairs?
The automatic bottom gasket retracts into the door, leaving a threshold-free passage while open.
STJH-AIRTIGHT-CLEANROOM-SWING-DOOR-DROP-BOTTOM
Airtight Cleanroom Swing Door Three-Side Gasket and Drop-Bottom
A swing door using three-sided EPDM contact and a retracting bottom seal for an unobstructed threshold.
- A moving bottom seal leaves no raised sealing sill.
- Three-sided EPDM contact follows the head and jambs.
- An anodized frame provides a finished aluminum wall interface.
Introduction de produit
An anodized aluminum frame supports the 50 mm single leaf and its three-sided EPDM gasket. A separate guillotine-type seal closes the gap below the blade, lowering as the door shuts and retracting for passage. The selected HPL-faced configuration keeps the wall-side surfaces flush and uses stainless operating hardware. Separating the bottom seal from the jamb and head gasket allows the doorway to retain a threshold-free passage for routine wheeled traffic.
Key Features
- A moving bottom seal leaves no raised sealing sill.
