When designing a new cleanroom or planning an upgrade of an existing cleanroom, it can be easy to get bogged down in the terminology. One such piece of terminology is pass-through chamber. Here we explain what a pass-through chamber is and its important features and benefits for cleanroom design.

What is a pass-through chamber?

A cleanroom pass-through chamber has a seemingly self-evident name: it’s a chamber through which you can pass materials. More specifically, it is a chamber that allows you to pass materials into and out of your cleanroom without your employees having to exit and enter the cleanroom and gown. Pass-throughs allow materials to enter the cleanroom while reducing the contamination entering the cleanroom. 

Pass-through chambers come in many different sizes and can incorporate many different materials, depending on the needs of your cleanroom. Heavy duty sealing locks prevent contamination from passing through the pass-through chamber when it isn’t being used, and double door designs can prevent cross-contamination issues. There are also stainless steel corrosion-resistant designs, fire safe designs, and chemical resistant chamber designs, along with designs that can incorporate HEPA-filtered air blowers. 

What are the benefits of pass-through chambers?

Pass-through chambers, since they allow materials to enter and leave the cleanroom without requiring employees to gown up and enter and exit the cleanroom, have obvious benefits for maintaining a high level of contamination control in the cleanroom environment. Additionally, pass-through chambers increase productivity because they allow employees to work more efficiently—no need to go through the time-consuming gowning and air-showering process every time an item is needed in the cleanroom. 

A pass-through chamber also reduces the number of employees who need to be in the cleanroom environment, cutting down on the potential for contaminants entering the controlled environment. It also means that you’ll need less costly gowns and other PPE on hand. 

What kinds of cleanrooms need pass-through chambers?

Any cleanroom that requires the transfer of materials into and out of the cleanroom on a regular or frequent basis could benefit from a pass-through chamber in their cleanroom design. Pass-through chambers are a feature that can be easily integrated into a new cleanroom design or installed into an existing cleanroom. Research facilities dealing with new and volatile substances, medical cleanrooms dealing with dangerous and contagious substances, pharmaceutical cleanrooms requiring a high level of sterility, and electronic and technology cleanrooms often incorporate pass-throughs in their cleanroom designs to manage contamination and keep productivity high. 

Whether you need pass thru chambers, air showers, or any other specialized cleanroom features, Angstrom Technology can design a cleanroom that incorporates those features.
