Cleanroom Air Showers
Cleanrooms are required to adhere to strict regulatory guidelines to prevent contamination. Coveralls and other protective gear are used to prevent outside contaminants from entering a cleanroom, but that isn’t always enough. Contaminants are easily transported by people and objects and a simple spec of lint or debris could cause issues in some cleanroom environments. Therefore, cleanroom air showers have become a vital component in maintaining the cleanliness of cleanrooms and other clean-critical environments.
Modular cleanroom air showers are enclosed chambers placed at the entry and exit points of a cleanroom or other controlled environment. Using high-velocity jets of air and HEPA or ULPA air filter systems, cleanroom air showers remove loose contaminants from people and products before they enter the cleanroom, reducing or eliminating product defects for increased yields.
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.

How Do Air Showers Work?
Modular cleanroom air showers are self-contained air recirculation systems. Installed as cleanroom entry systems, these phone booth-shaped units 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 from Clean Air Products
Cleanrooms are graded based on the level of particles present in the air. These grades are determined by ISO and U.S. federal standards, and changes in the level of contaminants can result in a different grade being assigned. Maintaining contaminant levels is critical, which is why you need a modular cleanroom shower that is reliable and effective.
Not all laboratory air showers are the same, and not all air showers perform the same in every situation. Only Clean Air Products’ air showers combine high-quality, all-metal construction with high performance, custom options and versatile configurations.
The Clean Air Products design advantage makes these cleanroom air showers easy to install and maintain. Our laboratory air showers deliver maximum efficiency and value for your cleanroom or other controlled environment.
Modular Cleanroom Air Showers Designed for Performance and ReliabilityOur 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.

How to Choose the Right Cleanroom Air Shower
When selecting a cleanroom air shower for your application, there are a number of factors that should be considered.
- The system should be modular, allowing for easy configuration (and reconfiguration), shipment, and assembly
- The shell of the air shower should be constructed of stainless steel or painted steel
- Blower system must supply high velocity, high volume air to ensure effective decontamination
- Recirculating filtration system should utilize pre-filters, followed by high-capacity HEPA filters
- The air shower should have a high number of adjustable, evenly-spaced air nozzles
- The unit should have a magnetic door interlock system, with appropriate controls
