Our Best-Selling Clean Systems
Ulpa Fan Filter Unit
This ulpa fan filter unit is integrates a HEPA/ULPA filter (99.99% efficiency on 0.3μm particles ) with a low-noise centrifugal fan. Its modular structure allows ceiling suspension or floor-mounted installation, adapting to ISO Class 1-100 cleanrooms . The rigid galvanized steel or stainless steel housing ensures corrosion resistance, while the split design simplifies filter replacement.
Cleanroom Door
This cleanroom door implements a triple-seal architecture combining magnetic compression strips, inflatable perimeter gaskets, and interlocking threshold profiles. Unlike conventional swing doors, our design achieves 99.97% airborne particle containment for particles ≥0.5 μm, effectively blocking microbial contaminants and process-generated aerosols.
Air Shower Booth
Unlike conventional systems, our air shower booth integrates pulsed airflow sequencing to dislodge submicron particles from lab coats, gloves, and footwear within 15 seconds. Proprietary nozzle arrays ensure uniform turbulence while reducing 40% energy consumption. Ideal for semiconductor fabs and biopharma facilities, this Air Shower Cabin adapts to multi-user workflows with motion-sensing activation and real-time particle counter feedback.
Key Features of Air Shower Booth
Multiple Chamber Design
Air shower booths often feature multiple chambers, including entry, shower, and exit chambers, each serving a specific purpose in the decontamination process.
High-Velocity Air Jets
Air shower booths use high-velocity air jets, typically powered by HEPA or ULPA filters, to blast contaminants off the surface of personnel and goods. The air jets are precisely placed to ensure uniform coverage and distribution of filtered air.
Advanced Filtration Systems
HEPA or ULPA filters are integrated into the air shower booth Key Features ofto ensure that the air used for decontamination is clean and free from contaminants. These filters capture particles as small as 0.3 microns, maintaining the highest level of air purity.
Control Systems
Air shower booths come equipped with touch-screen controls or buttons that allow users to activate the shower, adjust settings, and set decontamination duration. This includes microprocessor-controlled cycle times and various control panel options.
Safety Features
Emergency stop buttons and interlocking doors are standard features to ensure user safety and maintain the integrity of the decontamination process. The interlocks prevent multiple chambers from being opened simultaneously.

The Role of Air Shower Booth
Air shower booth protects products and employees against hazardous contaminants which could find their way into cleanroom. One instance of too much particulate can result in a ruined batch of pharmaceuticals or a malfunctioning piece of electrical equipment.
Air shower booth prevents these major problems from happening. It reminds employees the importance of remaining particle-free. Human is the main contaminating factor. The dust on the personnel's body will be removed after going through air shower, minimizing the contamination.

The length of the air shower booth is usually determined based on the number of people in the workshop. If there are about 20 people in the workshop, one person can pass through each time, so that more than 20 people can pass through in about 10 minutes. If there are about 50 people in the workshop, you can choose one that passes through 2-3 people each time. If there are 100 people in the workshop, you can choose one that passes through 6-7 people each time.
Please do not place air shower booth near high-speed dust sources and earthquake sources. Please do not use volatile oil, diluent, corrosive solvents, etc. to wipe case to avoid damaging the paint layer or causing discoloration.
The following places should not be used: low temperature, high temperature, high humidity, condensation, dust, and places with oil smoke and mist.
