How to Maintain Clean Room Doors for Long-Term Performance

In critical environments like pharmaceutical manufacturing and laboratories, Clean Room Doors play a vital role in maintaining hygiene, pressure differentials, and contamination control. These doors aren’t just entry points—they're engineered barriers, ensuring your cleanroom stays sterile and efficient.

To get the most out of these high-performance doors, regular maintenance and an understanding of their build are essential. Let’s dive into the structure, features, and tips for long-term performance of clean room doors.

Understanding Clean Room Doors: Build and Design

Construction:

Clean room doors are double skin doors with or without view panels, constructed similarly to modular panels and assembled with a specialized door profile. Their core materials and structural integrity make them robust for cleanroom applications.

• Material of Construction:

  • Standard Doors: GPSP GI Sheet (0.8 mm thick) with Frame (1.2 mm thick)

  • Fire-Rated Doors: GPSP GI Sheet (1.2 mm thick) with Frame (1.6 mm thick)

• Shutter Thickness: 42 / 44 / 46 mm

• Door Sizes Available:

  • Thickness: 50 mm, 80 mm, 100 mm, 150 mm

  • Width Options: 750 mm to 2200 mm

Finish:

• Powder Coated / Stainless Steel

• Powder Coating Thickness: 60–80 microns

Key Features and Accessories

High-quality Clean Room Doors come equipped with:

• Hinges: 3–4 stainless steel hinges per door

• Handles: Stainless Steel ‘D’ type (20 mm dia, 300 mm long)

• Push Plate: 125 x 300 mm

• Closers: Dorma TS-68 standard arm

• Locking: Both side key-operated

• Bottom Seal: Automatic door bottom seal

• Glass Panel: 6 mm thick safety glass view panel

• Panic Bar: For emergency exits

• Kick Plate: 300 mm height stainless steel

Filler Material Options:

• PUF: 40±2 kg/m³

• PIR: 48±2 kg/m³

• ROCKWOOL: 96±2 kg/m³

Tips to Maintain Clean Room Doors for Long-Term Performance

1. Routine Inspection: Regularly check hinges, handles, closers, and bottom seals. Tighten or replace components as needed.

2. Clean Seals & Panels Gently: Use a soft cloth with mild disinfectants. Avoid abrasive cleaners that can degrade powder coating or stainless steel surfaces.

3. Lubrication: Periodically lubricate hinges and lock mechanisms with suitable non-contaminating lubricants.

4. Check Door Alignment: Misaligned doors can compromise sealing efficiency. Re-align promptly to maintain air pressure and cleanliness standards.

5. Inspect View Panels and Safety Glass: Clean with non-scratching agents and check for any cracks or fogging that might compromise visibility or safety.

6. Maintain Interlocking Systems: Ensure electronic interlocks and door closure mechanisms function without lag or failure.

7. Filler Material Integrity: Ensure there's no sagging or shifting in the filler material that may reduce thermal or acoustic performance.

Final Thoughts

Clean room doors are engineered for performance, but like any critical component, they demand consistent attention. By understanding their construction and following a proactive maintenance routine, you can ensure optimal performance, compliance, and longevity.

When selecting or maintaining Clean Room Doors, always prioritize quality materials and experienced installation partners—because in controlled environments, every detail counts.
