Enclosure Solutions for Maintaining Clean Room Environment

In most cases, organizations invest in enclosure solutions to protect their electronics from dangerous particulates floating around the environment.

The enclosures are set up to produce a positive-pressure interior air system–the fan pulls air through a filtered intake. The clean air is used by the electronics to keep the system cool, and then it’s expelled back into the environment via the cable port or other opening.

Some organizations, though, need to keep certain electronics in a clean room, which is a controlled environment where pollutants and particulates are filtered out to create the cleanest area possible. Clean rooms are often found in organizations that manufacture electronic, pharmaceutical and medical products.

This means that while most production and warehouse facilities are trying to keep harmful particulates found in the room from getting into the electronics, organizations who rely on clean rooms need a way to protect the room and its contents from the airborne particulates that can be expelled by printers and other electronics.

At DustShield®, we’ve developed a solution that allows us to protect the room while still providing ventilation to the electronics.

Clean Room Enclosure Solutions

Organizations often invest a significant amount of capital to set up and build a clean room. Therefore, they will do everything they can to ensure the environment continues to meet the clean room standards.

Some electronics, though, expel particulates that could contaminate the environment. For example, printers can exhaust paper dust or ink particulates into the air through their normal functions.

To combat this, the DustShield engineers create a negative air pressure system inside the enclosure. Instead of pulling air into the enclosure via a filtered port, the fan pushes air out of the enclosure via a filtered port. To help ensure air only goes out through the filter, our team will often put grommets on all cable entry points. This means that air will only come in via the paper port and out through the filtered opening.

In some cases, the electronic system can be as sensitive as the environment. In that instance, our team can set up a two-filter system as a redundancy. We will ensure all openings are closed except two, both of which will have a filter. The fan pulls the air through one filtered opening and then blows it out the other. Depending on the size of the enclosure, the equipment and even the environment, the DustShield team might determine that a second fan will be beneficial as well.

Submicronic Filters

Regardless of how the system is set up, the filters are the star of the show and the part that will ensure the clean room environment stays clean.

At DustShield, our filters are designed to remove all airborne particulates down to .1 micron. That makes them 6x more effective than most permanent, washable electrostatic filters. As long as the organization is properly installing the filters and replacing them regularly, the filters will help keep the electronics inside the enclosure safe and clean for years to come.
