A Guide to Essential Cleanroom Equipment

Cleanroom environments are ideal for safely handling specimens, conducting tests, and manufacturing and assembling sensitive goods. Properly maintaining air purity and protecting workers, devices, and products within the space, however, requires a combination of essential cleanroom equipment and protective garments to achieve. In this guide, we’ll review air handling and filtration, PPE, and cleaning equipment solutions to help ensure your cleanroom remains compliant with industry standards.

A Guide to Essential Cleanroom Equipment

Air Handling and Filtration Systems

Supplying and maintaining clean air within a cleanroom is a top priority. Four common types of air handling and filtration equipment that make this possible include the following:

  • High-Efficiency Particulate Air (HEPA) Filters. HEPA filters are a critical component of a successful cleanroom for reliably purifying the air. These filters remove 99.99% or more of particles sized 0.3 microns and up.
  • Air Handling Units (AHUs). These systems help ensure the consistent circulation of purified air while carefully controlling cleanroom conditions. Based on the needs of your application, AHUs effectively manage certain aspects of the air within the space, such as its flow, humidity level, and temperature.
  • Laminar Flow Equipment. Managing air’s flow direction and velocity can be just as important as controlling its humidity and temperature. Laminar flow equipment creates continuous streams of filtered air through a space and across surfaces in a particular direction, such as away from equipment for sterile operations.
  • Pass Thrus. Also called pass-through airlocks or communicators and package transfer units, cleanroom pass thrus allow you to safely transfer items from an exterior space to your controlled interior environment to limit contamination.

Personal Protective Equipment (PPE)

Head and face coverings, clothing, and other equipment help protect workers from breathing in or coming into contact with harmful substances. At the same time, PPE minimizes the chance of cleanroom contamination from dirt, fibers, hair, or skin cells. Some common examples of PPE include:

  • Caps, Hoods, and Related Coverings. These garments keep loose hair from falling onto equipment and work surfaces.
  • Safety Goggles or Glasses. This eye protection keeps airborne particles from entering your eyes, along with any splashed substances.
  • Face Masks. Fully covering your mouth and nose, these masks serve a dual purpose. Face masks protect a cleanroom environment from contaminants you exhale while preventing you from inhaling harmful particles into your respiratory system.
  • Coveralls. These cleanroom garments will provide full-body coverage, from your neck to your wrists and ankles. Usually consisting of materials that develop and shed minimal lint, they protect you and your clothes while reducing fiber and particle contamination in the cleanroom.
  • Gloves. Gloves are another example of PPE offering dual protection. They provide you with a layer of protection between your hands and harmful substances, and gloves lessen the chance of particle transfer onto handled materials.
  • Booties and Overboots. This PPE prevents you from tracking dirt and other contaminants into a cleanroom on the soles of your shoes.

Maintenance and Cleaning Equipment

Proper air filtration and strict PPE use will prevent many potential sources of contamination from compromising your cleanroom. However, additional equipment options are available to help you maintain your cleanroom space.

For example, you can place shoe brush machines near a cleanroom entrance. These units scrape dust and dirt off the bottom of shoes using stiff bristles to reduce the risk of contamination from footwear. Sticky mats, or tacky mats, supplement shoe brush machines, their sticky surfaces pulling contaminants from the bottom of your shoes as you cross over the mat. Wipes, disinfectant solutions, and roll mops also allow your cleaning teams to wipe away and remove contaminants that made their way to surfaces within the cleanroom.
