Model 008 Cleanroom High-Speed Sealing Door
The Model 008 Cleanroom High-Speed Sealing Door is designed for indoor industrial applications where space efficiency, controlled air sealing, and reliable environmental separation are required.
Requiring minimal installation clearance, Model 008 creates an effective barrier against air drafts, humidity, dust, and particulate contamination. By combining rapid opening speeds with perimeter seal track technology, this door helps maintain comfortable interior working conditions, supports smooth internal logistics, and reduces facility energy loss.
Key Engineering Features
- Fast Cycle Operation for Internal Traffic Flow
- Opening speed up to 1.2 m/s | Closing speed: 0.5 m/s. Minimizes doorway open times to reduce air exchange between adjoining rooms.
- Automatic Curtain Reinsertion System
- If the curtain is dislodged from its side guides due to an accidental impact, it is designed to automatically reinsert during the next opening cycle, reducing the need for manual resetting and minimizing operational interruptions.
- Space-Efficient Compact Construction
- Features a compact Steel – Ø 102 × 2 mm roller barrel assembly, engineered to fit indoor passageways with restricted headroom and side clearances.
- Perimeter Sealing Track Technology
- Integrated seal track design and precision curtain welding deliver Class 1 Air Permeability under standard test conditions, preventing unwanted particulate infiltration.
- Soft-Edge Safety Protection
- Flexible Curtain Structure: Built with a soft curtain containing no rigid metal bars or stiffeners, reducing risk to personnel and passing equipment.
- Wireless Anti-Pinch Safety Edge: Integrated at the bottom to detect contact and reverse door travel upward immediately.
- In-Track Photocells: Standard photoelectric sensors fitted inside the guide tracks monitor the doorway during movement.
- Frequency Inverter (VFD) Drive System
- The 0.75 kW – 1.5 kW drive motor is managed by a variable frequency drive to enable smooth acceleration and deceleration (soft start/stop), helping provide smooth and controlled door movement while extending component lifespan across its 1,000,000-cycle durability rating.
- IP55 Multi-Function Control Unit
- Supplied with an IP55-rated wall-mounted control box equipped with Open / Close / Stop pushbuttons, a master power switch, and expandable interfaces for interlocking, radar sensors, induction loops, and building management systems (BMS).

Frequently Asked Questions (FAQ)
A: If a cart or transport vehicle accidentally strikes the curtain and dislodges it from the side tracks, the guide system is engineered to automatically guide the flexible curtain edge back into the low-friction C-channel during the subsequent upward opening cycle, reducing the need for manual resetting and minimizing operational interruptions.
A: Model 008 is supplied with a galvanized steel frame as standard. An optional stainless steel construction is available for facilities with higher hygiene requirements or washdown cleaning protocols.
A: The door combines sealed side guides, welded curtain profiles, and an opening speed of up to 1.2 m/s. This configuration helps restrict dust, moisture, and particulate ingress between partitioned zones while limiting HVAC energy loss.
A: Model 008 includes a full multi-point safety system: a flexible soft curtain containing no rigid metal components, a wireless safety edge sensor that reverses door movement upon contact, and dual photoelectric sensors integrated inside the side tracks to prevent closure when an obstruction is present.
A: Yes. The IP55 VFD control unit includes configurable I/O interfaces that allow direct connection to cleanroom interlock controllers, radar sensors, induction floor loops, pushbuttons, and facility management systems.
