A slim mechanical door-bottom assembly that retracts its silicone blade while the door moves and lowers it evenly against the floor when a single end plunger meets the jamb.
- Single-Side Plunger Actuation
- Parallel-Drop Silicone Blade
- Slim Aluminum Carrier
- No Electrical Connection
مقدمة المنتج
This automatic door drop seal is a narrow mortised assembly for the bottom edge of cleanroom swing doors. A jamb-contacting plunger transfers closing movement through a spring-loaded linkage inside the extruded aluminum carrier. The linkage lowers one continuous silicone blade after the door reaches the frame and returns it into the carrier as soon as the door opens. The self-levelling movement helps the blade follow modest floor variation without dragging across the walking surface during the swing cycle.
الخصائص الرئيسية
A spring-return pushrod and pivot linkage retract the blade promptly to reduce scraping, rolling resistance and premature elastomer wear.
The continuous dark silicone blade descends in a parallel action to close the under-door air path across the full leaf width.
The slim natural-aluminum carrier can be recessed into the door bottom and serviced from the actuator end without a floor-mounted track.
مخاوف المنتج للعملاء
Reliable under-door sealing requires enough blade travel for the finished gap, accurate plunger contact and free retraction before the door begins to swing.
A fixed sweep drags across resin or vinyl flooring, increasing door force and shedding worn seal material near a controlled area.The spring-return linkage lifts the silicone blade clear of the floor immediately after the plunger releases.
A floor that is slightly out of level can leave one end of a rigid door-bottom gasket open.The parallel-drop, self-levelling carrier allows the continuous blade to seat across the opening while maintaining a single uninterrupted seal line.
An over-extended actuator can force the mechanism beyond its useful travel and shorten component life.The accessible end plunger provides controlled stroke adjustment so the blade reaches the floor near the final closed position.
A bulky surface-mounted device can conflict with cleanroom door skins, kick plates or flush architectural details.The narrow extruded carrier fits a prepared mortise in the door bottom, leaving only the end actuator and descending seal function exposed.
