1.2m Cleanroom Unequal Double Door: Custom Swing & Sliding Doors

Maintaining air pressure stability while accommodating industrial cart traffic is a major layout challenge. The 1.2m cleanroom unequal double door (子母门) is an engineered structural choice designed precisely to bridge the gap between daily personnel transit efficiency and heavy material transfer clearances.

The Core Problem: Air Leakage vs. Logistical Access

Standard single doors are too narrow for industrial equipment carts, while large symmetrical double doors cause significant air volume loss every time they open. The unequal configuration addresses both issues simultaneously by offering dynamic flexibility:

• During Daily Operations: Only the primary active leaf (typically 800mm to 900mm wide) opens, reducing cross-contamination risks and conserving conditioned air.
• During Equipment Transfer: The secondary inactive leaf can be unlocked, expanding the clear opening to a full 1.2 meters to allow machinery or wide pallets to pass.

Comparing Swing vs. Sliding Configurations

At Farclean, we manufacture this versatile 1.2m footprint in two primary functional formats depending on your spatial constraints:

Option A: Custom Swing Doors

Ideal for standard corridors and changing zones. Equipped with heavy-duty stainless steel hinges and specialized drop-down bottom seals, these doors automatically drop an airtight gasket when closed to prevent pressure loss across rooms.

Option B: Automatic Sliding Doors

Perfect for high-traffic zones or tight spaces where a swinging door leaf would block evacuation paths or adjacent 1.2-meter wide corridors. These can be integrated with touchless infrared wave sensors or foot-switch controls to support hands-free material handling.

Material Specifications & Cleanroom Integration

Every 1.2m unequal door manufactured by Farclean features premium materials built for heavy industrial usage. The cores are insulated with high-density flame-retardant materials, while the exterior sheets are treated with antibacterial powder coatings or finished in 304/316L stainless steel to resist harsh chemical wipe-downs. They are engineered to integrate completely flush with modular wall panels to eliminate dust-accumulating ledges.
