Clean Booth
STJH Cleanroom provides compact, flexible, and cost-effective clean booth solutions designed to create local high-cleanliness areas inside existing workshops. A clean booth is often used as a mini cleanroom for production, testing, assembly, and process protection.
Create a local clean area with STJH Cleanroom
A clean booth is a practical solution when you only need a clean environment for a specific process, machine, workstation, inspection area, or small production zone. Instead of building a full cleanroom for the entire workshop, a clean booth creates a controlled clean space exactly where it is needed.
This makes it especially valuable for factories that need fast improvement, limited clean areas, flexible production changes, or a lower-cost cleanroom alternative. It is a small but powerful cleanroom solution for many industrial applications.
What is a clean booth?
A clean booth, also called a clean shed, softwall cleanroom, clean enclosure, or mini cleanroom, is a localized air purification system. It usually consists of a metal or aluminum frame, FFU fan filter units, HEPA or ULPA filters, ceiling panels, lighting, anti-static PVC curtains or rigid wall panels, and a clean working area below.
The FFU draws air from the surrounding environment, filters it through high-efficiency filters, and sends clean air downward into the booth. This creates a cleaner local area for sensitive production steps. Compared with a full cleanroom, a clean booth is smaller, faster to build, easier to move, and more economical.
A local cleanroom for focused contamination control
Not every factory needs a full cleanroom. Many customers only need to protect one production line, one machine, one assembly process, or one inspection area. In this situation, a clean booth can provide the required local cleanliness without changing the entire building.
Clean booth vs. cleanroom vs. modular cleanroom
Clean booths, modular cleanrooms, and standard cleanrooms all help control contamination, but they are used for different project needs. The clean booth is the most compact and localized option.
| Comparison | Clean Booth | Modular Cleanroom | Standard Cleanroom |
|---|---|---|---|
| Project Size | Small local clean zone | Room-level clean space | Full cleanroom facility |
| Installation Speed | Very fast | Fast | Usually longer |
| Cost Level | Lower cost | Medium project cost | Higher construction cost |
| Flexibility | Easy to move and adjust | Expandable and relocatable | More fixed after construction |
| Best Use | Machine area, workstation, testing, assembly | Production room, factory upgrade, line expansion | Permanent production facility |
| Main Advantage | Local cleanliness with minimal construction | Fast room-level cleanroom solution | Comprehensive facility-level control |
Key advantages of clean booths
Local High Cleanliness
A clean booth creates a cleaner local area around key processes, helping protect sensitive products without upgrading the whole workshop.
Fast Installation
The structure is simple and modular. Most clean booths can be installed much faster than traditional cleanroom construction.
Lower Investment
Because it only controls a selected area, a clean booth can reduce project cost compared with building a complete cleanroom.
Movable Design
The booth can be relocated or adjusted when production lines change, making it suitable for flexible manufacturing environments.
Easy Expansion
Additional FFUs, larger frames, curtains, or connected booths can be added when the clean area needs to grow.
Simple Maintenance
The structure is easier to inspect, clean, maintain, and modify than a large cleanroom system.
Main structure and components
Typical applications
Electronics Assembly
Protect dust-sensitive electronic components, precision parts, screens, optical parts, and assembly processes.
Laboratory Testing
Create a cleaner local environment for sample handling, testing, and small-scale experimental operations.
Medical Device Production
Provide a local clean zone for assembly, inspection, packaging, or process protection.
Precision Manufacturing
Reduce particle contamination around high-precision machines and sensitive workstations.
Inspection Area
Build a cleaner space for quality inspection, visual checking, and final product handling.
Existing Workshop Upgrade
Quickly improve local cleanliness without rebuilding the entire workshop.
Available cleanliness levels
Clean booths can be designed for different cleanliness levels depending on the number of FFUs, filter efficiency, booth size, airflow design, surrounding environment, and operating conditions. For many applications, a clean booth is an efficient way to achieve a local clean zone inside a general workshop.
| Cleanliness Level | Typical Configuration | Suitable Use |
|---|---|---|
| ISO Class 5 | Higher FFU coverage and strict airflow control | Critical local processes and high-cleanliness work areas |
| ISO Class 6 | Enhanced filtration with stable clean airflow | Electronics, medical devices, precision assembly |
| ISO Class 7 | Balanced clean booth configuration | General clean assembly, inspection, packaging |
| ISO Class 8 | Cost-effective local cleanliness improvement | Workshop upgrade, material handling, support processes |
When should you choose a clean booth?
Choose a clean booth when you do not need a full cleanroom, but you still need a controlled clean area for a specific process. It is especially useful when budget, installation time, workshop space, or production flexibility are important.
For many factories, a clean booth is the fastest way to improve local cleanliness, protect product quality, and start cleaner production with less investment.
How we design your clean booth
We confirm booth size, process type, equipment, operators, and required cleanliness level.
We plan FFU quantity, air supply direction, filter type, and airflow coverage.
We design the frame, curtain or panel enclosure, lighting, access, and supporting options.
The clean booth is assembled quickly and prepared for local clean production.
Need a clean booth for your workshop?
Tell STJH Cleanroom your booth size, product type, required cleanliness level, workshop condition, and process layout. We can help you design a compact clean booth solution for your local clean production area.
