1. First, look at the 3 most crucial conditions (determining the type of door)
Is the channel width sufficient?
Is there space on both sides? → Choose an automatic sliding door (with good sealing and high cleanliness)
Is the channel narrow and without side positions? → Must be a rolling shutter door
What is the size of the goods?
Small carts, pallets → A sliding door is sufficient
Extremely wide, extremely tall, for forklifts / AGVs → A rolling shutter door
What is the cleanliness level?
Class 100 / Class 1000 / strict GMP → Prefer a sliding door
Class 10,000 / Class 100,000 / logistics passage → A rolling shutter door is more cost-effective
2. Then determine the type of washroom
Single-person single-air shower room: for personnel, not for goods
Washroom (double-door interlocked): dedicated for goods
Washroom passage: for large-scale continuous cargo passage
Corner washroom (L-shaped): limited space, requires turning
3. Match quickly according to the usage scenario
Food / Medicine / Electronics high cleanliness
Automatic sliding door washroom → Strong sealing, easy cleaning, in line with GMP
Warehouse / Logistics / Frequent entry and exit of workshops
Rolling shutter door washroom → Resistant to impact, quick opening, no space occupation
For forklifts, large equipment entry
Large-sized rolling shutter door washroom
Very narrow space
Rolling shutter door or L-shaped corner washroom
4. How to choose the material
201 stainless steel: ordinary cleanroom, dry environment
304 stainless steel: food, medicine, moisture-proof, rust-proof
316 stainless steel: corrosive environment, high-requirement clean area
5. Control and functions must be seen
Must have double-door interlock (to prevent contamination)
Photoelectric induction / infrared induction
Emergency stop, door status indication
Optional: PLC, adjustable air shower time, automatic door opening
6. The simplest summary (copy directly)
To be clean, to be sealed, goods are not large → Automatic sliding door washroom
Narrow channel, large goods, for forklifts, need efficiency → Rolling shutter type washroom
