Ideal for standard pharmaceutical, biotech, and electronics cleanrooms requiring dry particle removal.
Adds fine mist (water or disinfectant) via high-pressure pump to wet and bind dust/potent particles, preventing resuspension—ideal for toxic dust or APIs. Followed by air jets to remove excess moisture and contaminants.
- Dual-function cycle: mist to bind particles + high-speed air to purge
- Low-flow wet spray condenses fine dust for easier capture and filtration
- Stainless steel build with containment features for safety
- Auto-inductive entry, interlocks, and full control supervision
- Suitable for Class D or higher environments (5–40°C operating range)
- Customizable for high-potency or chemical handling zones

FAQs for Better Results
What is the purpose of an Air Shower?
An Air Shower acts as a personnel/material decontamination airlock at cleanroom entrances. It uses high-velocity HEPA-filtered air jets to remove loose particles, dust, and contaminants from garments, hair, and surfaces—preventing them from entering the controlled environment and supporting GMP compliance.
How does a standard Air Shower work?
Upon entry, the interlocked chamber activates automatically. Adjustable stainless steel nozzles deliver high-velocity HEPA-filtered air jets (>25 m/s) to dislodge particles. Users rotate and raise arms during the timed cycle (adjustable, typically 10–30 seconds). Contaminated air is drawn through HEPA (≥99.99% @ 0.3 μm) + G4 pre-filters and recirculated. Exit is blocked until the cycle completes and purge finishes.
What is a Mist Air Shower (Spray Blowing Shower), and when should I use it?
The Mist Air Shower adds a fine water mist (or optional disinfectant) phase via high-pressure pump and copper nozzles to wet and bind adhered dust, potent particles, or toxic residues—preventing resuspension and airborne spread. It’s ideal for handling APIs, hazardous powders, or high-potency compounds where dry air alone may not suffice. After misting, air jets remove excess moisture and remaining contaminants.
What filtration is used in LENGE Air Showers?
Standard models feature multi-stage filtration: G4 pre-filters + HEPA filters (≥99.99% efficient @ 0.3 μm). Mist versions maintain similar high-efficiency filtration while the mist phase enhances particle capture for hazardous applications.
Are Air Showers customizable?
Yes — fully customizable to your needs. Options include size, layout (straight-through, 90° turn, tunnel/multi-user), nozzle count/location, materials (SUS304/316L), controls, interlocks, and integration features like VHP compatibility or special finishes.
What noise level and operating conditions can I expect?
Noise is typically 65–75 dB(A) for standard models. Units operate reliably in pharmaceutical environments (5–40°C range), with low-noise, energy-efficient direct-drive blowers for consistent performance.
What controls and safety features are included?
Microprocessor control panel with programmable cycles, LED indicators, emergency stop, fault alarms, differential pressure monitoring, magnetic interlocks, and luminous power buttons. Auto-inductive entry and full supervision ensure safe, reliable operation.
What applications are Air Showers / Mist Air Showers best suited for?
Primarily pharmaceutical, biotech, and API manufacturing cleanrooms (Grade D or higher) for personnel/material entry decontamination. Standard versions suit general particle removal; Mist versions excel in high-potency, toxic dust, or sensitizing powder handling to protect operators and prevent cross-contamination.
