Air showers are specialized enclosed antechambers which are incorporated as entryways of cleanrooms and other controlled environments to reduce particle contamination. Air showers utilize high-pressure, HEPA- or ULPA-filtered air to remove dust, fibrous lint and other contaminants from personnel or object surfaces. The forceful "cleansing" of surfaces prior to entering clean environments reduces the number of airborne particulates introduced.When properly incorporated into cleanroom design, air showers provide an ISO-classified transition vestibule to ensure the cleanliness of the classified cleanroom. Air showers are typically placed between a gowning area and cleanroom; after workers don appropriate garb and personal protective equipment, they enter the shower so that the pressurized air nozzles remove any residual particles from coveralls. Once the program cycle is complete, users exit out through a second door, into the cleanroom. Air showers (or air tunnels) may also be placed between cleanrooms of different ISO ratings.

Air Shower Description:

Air shower is a kind of partial clean equipment which is installed at the partition between the clean and non-clean rooms. It’s used for people and goods to shower before entering the clean area. After using it, the dust could effectively be reduced to enter the clean area and maintain the normal working status.

Air Shower equipped with PRE filter and HEPA filter, by double-layers filtration system to ensure high air cleanness level. Air shower is widely used in LCD and electronic Display, PCB, microelectronics, dust-free coating, aseptic packaging, medical care, Pharmacy,auto glass and precision parts.

We can assembly air showers or passages in various lengths as per the number of people that may enter into the clean room.

Shower means: one side shower, double sides shower, three sides shower, top shower.

Features:

1. The control system run automatically by photoelectric sensor, the two door are electric interlocked.   (One door in open state, the other door must in close state. When people enter air shower, the system will shower automatically by photoelectric sensor)

2. Air shower time from 0 to 99 seconds which can be adjustable

3. Adopt Pre filter and HEPA filter 4. The door, bottom-board, nozzles are used of stainless steel, good appearance.

5. When air shower is used to pass cargo, it is without bottom-board.

  Optional accessory:
1. Manual swing doors/ automatic sliding doors /High speed shutter doors

2. HEPA filter or ULPA filter

3. Material for cabinet: cold-rolled steel plate with powder coated / SUS#201 / SUS#304

4. Common fluorescent lamp

5.  With voice announce

6. Emergency switch

Air Showers are Used for a Variety of Applications

Installed as cleanroom entry systems, air showers reduce contamination as personnel enter the clean production space. A worker passes through the entry door, the door closes, and high velocity streams of HEPA filtered air is blown onto the worker from numerous precisely placed, adjustable nozzles. This high velocity air creates a flapping effect on the worker’s clothing, which allows contaminant to be removed from their cleanroom garments.

As the cycle ends, the exit door unlocks, and the worker exits the air shower into the cleanroom. Typical cycle time is ten seconds. An adjustable microprocessor allows for easy “on-site” adjustment of cycle times and other critical process controls.

Cleanroom air showers can also be used to remove particulates as personnel leave areas before going out into the general public, or to prevent cross-contamination when workers move from one workspace to another.

Air showers for cleanrooms are used in a variety of industries where contamination could be detrimental, including:

• Biomedical
• Pharmaceuticals
• Aerospace
• Microelectronics
• Precision Manufactur

Benefits of Air Showers

Air showers are only a small percentage of the cost for the entire cleanroom, but they can save you thousands by preventing contamination that could affect the quality or usefulness of products and equipment.

Additionally, modular cleanroom air showers reduce the need for cleanroom maintenance because the contamination load will be lower. Your cleanroom’s HEPA and ULPA filters will last longer, and overall energy costs will be reduced. Air showers for cleanrooms can also improve efficiency by limiting particle buildup. This improves the efficiency of the HEPA filters by putting less stress on them.

Air showers provide the cost-effective contamination control technology that your applications need to improve the quality of your products.

Types of Air Showers from Clean Air Products

Our modular cleanroom air showers are made from durable, heavy gauge painted steel construction and feature high velocity air filter systems for fast, efficient cleaning. Magnetic interlocks secure the entry and exit points, and LED lighting provides high visibility in low-light environments.

Standard-size HEPA filters and prefilters are installed for zero-leak, negative pressure reliability seals and silicone-free urethane sealant ensure a tight seal throughout the cleanroom air shower.

Laboratory air showers from Clean Air Products also feature microprocessor-controlled cycle times and touchscreen controls that make our laboratory air showers easy to use. When maintenance is required, the inspection panels provide access for fast and easy service.
