SEPPES Lab Doors Case Study- airtight pvc roller doors
In high-tech industries such as pharmaceuticals, laboratories, electronics, and food processing, maintaining a controlled environment is critical. Dust, air leakage, and pressure fluctuations can directly affect product quality. This is why airtight roller doors are widely used as clean room doors and lab doors in positive pressure airlock systems.
This article shares a real project case and explains when to choose clean room fabric door solutions, when not to choose them, and how to maintain them for long-term performance.
A customer required four airtight interior doors for two clean room airlocks with positive pressure (bubble type) to prevent dust from entering or escaping. The door specifications were:
- Door size: 6′ (W) × 10′ (H)
- Material: PVC fabric
- Application: Clean room airlocks
- Function: Airtight sealing, fast opening and closing, automatic operation
Based on this requirement, we recommended automatic clean room doors using high-speed clean room fabric door technology to ensure airtightness and stable air pressure.
Why Airtight Roller Doors Are Used as Clean Room Doors
Compared with traditional steel doors, airtight roller doors are more suitable for clean rooms and laboratories because they provide:
- High airtight performance for positive pressure environments
- Fast opening and closing to reduce air exchange
- Smooth PVC surface for easy cleaning
- Automatic operation to improve efficiency
- Flexible curtain to reduce safety risks
For this reason, many clean room doors manufacturers recommend clean room fabric door systems for airlock areas instead of traditional hinged doors.
When to Choose Airtight Roller Doors
Airtight roller doors are the best choice when your facility has the following requirements:
- Clean rooms with positive or negative pressure
- Air lock doors between clean room and non-clean area
- Laboratories that require lab doors with high sealing performance
- Frequent traffic areas where doors must open and close quickly
- Environments that require automatic clean room doors
Typical industries include:
- 제약 공장
- Semiconductor manufacturing
- 식품 가공 공장
- Laboratories
- Electronics production workshops
In these environments, clean room doors must maintain airtightness while operating quickly, which is why clean room fabric door systems are widely used.
When Not to Choose Clean Room Fabric Door
Although airtight roller doors are ideal for clean rooms, they are not suitable for all environments.
You should not choose this type of door if you need:
- Fire-rated doors
- Heavy impact resistance (e.g., heavy forklift collision areas)
- Extremely large industrial exterior doors
- High-security steel doors
In these cases, steel roller shutters or sectional doors may be more suitable than clean room fabric door systems.
How to Maintain Automatic Clean Room Doors
To ensure long-term airtightness and performance, regular maintenance is important.
Maintenance tips:
- Clean the PVC curtain regularly to prevent dust accumulation.
- Check the sealing brushes and bottom seal to maintain airtight performance.
- Inspect the motor and control system to ensure smooth operation.
- Check guide rails to ensure the curtain runs smoothly.
- Repair small damages immediately to avoid air leakage.
Proper maintenance will extend the service life of automatic clean room doors and keep the clean room environment stable.
