In the realm of advanced door technology, QUALIA's Pneumatic Seal APR Doors stand out as a game-changer, especially in high-traffic areas, cleanrooms, and laboratories. Here’s a detailed look at the features and benefits of these innovative doors.

Eliminating Tripping Hazards

One of the most compelling features of QUALIA's Pneumatic Seal APR Doors is their ability to reach flush thresholds. This design eliminates the inherent tripping hazards associated with traditional mechanical seal doors, creating a safer and more accessible environment for everyone.

Superior Air Tightness

These doors are engineered to deliver exceptional air tightness, making them ideal for applications involving high traffic flow, wheeled equipment, or large animals. Whether it's a busy hospital corridor, a pharmaceutical facility, or a biosafety laboratory, QUALIA's Pneumatic Seal APR Doors ensure a tight seal that prevents contaminants from entering or escaping.

Unique Working Principle

The working principle of these doors is both simple and ingenious. When the door is open, the inflatable seal strip deflates and retracts into its groove. Upon closing, the seal strip inflates and expands, creating a firm seal between the door leaf and the frame while the door is securely locked. This mechanism ensures that the seal remains intact, even in the most demanding environments.

Key Features of QUALIA's Pneumatic Seal APR Doors

Material and Construction

• Door frames and leaves are made from 304 stainless steel, with a frame thickness of at least 5mm and a door leaf thickness of at least 1.5mm.
• Full welding construction ensures the door surface flatness does not exceed 1mm over a 1-meter range.

Seal Integrity

• The inflatable seal provides ±2000Pa pressure with a decay of less than 0.5% Vol/h over 20 minutes.

Safety Features

• Emergency deflation valves are located on both sides of the door, allowing personnel to take immediate action in case of a power outage or other emergency.
• Automatic deflation if the inflation value exceeds 0.2 MPa and automatic inflation if it falls below 0.18 MPa.

Ease of Maintenance

• The unique design allows a single person to replace the seal strip, thanks to the innovative lift-hinge mechanism, eliminating the need for multi-person door dismantling.

Versatility and Integration

• These doors can be used independently or in multiple combinations, featuring single or interlocking multiple doors. The integrated operation handle conceals the electromagnetic interlock.

Additional Features

• Viewing windows made of 12mm thick tempered glass, disc-style.
• The inflatable seal is made from high-density ethylene-propylene-diene monomer (EPDM), offering superior corrosion, oxidation, and chemical resistance.

Comparison with Competitors

Applications

QUALIA's Pneumatic Seal APR Doors are used primarily in high containment and high traffic situations where air leakage cannot be permitted, such as:

• Bio-hazard laboratories (BSL3, BSL4, BSL3-Ag and BSL4-Ag)
• Pharmaceutical laboratories
• Medical clean rooms.

These doors facilitate superior sealing during cleanroom facilities and laboratory purification and fumigation processes, ensuring a controlled and secure environment.

Conclusion

QUALIA's Pneumatic Seal APR Doors represent a significant advancement in door technology, offering a perfect blend of safety, efficiency, and ease of maintenance. With their innovative design, high-quality materials, and enhanced safety features, these doors are the ideal solution for maintaining superior air tightness and ensuring a safe and secure environment in various high-demand settings.
