Glove boxes- Filtration

A very significant segment of a glove box or any containment designated area is its filtration system.

A glove box filter system for filtering out particles from a glove box environment is specifically in a glove box having an outlet and an inlet.

Filters are a crucial part of a glovebox, especially as requirements for creating and maintaining gas purity continue to increase.

Filters perform several roles:

• Protect the environment from harmful particulates that could be released to the atmosphere  when the glovebox is accessed or vented
• Protect the material in the glovebox from environmental particulates that could enter the glovebox
• Protect your equipment from the materials used in the glovebox

          A glovebox can include several types of filters:

• An inlet/supply filter to prevent workers from coming in contact with any materials within the glovebox should the box become positively pressurized
• A prefilter to collect large particulates before the inlet HEPA filter.
• A HEPA or ULPA filter to trap smaller particulates and contain toxic materials.
• An exhaust filter to trap any remaining particulates before exhaust air is released out to the external exhaust system.

Filters are usually installed within a modular housing or mounted on top of the glovebox. Filters mounted on top of the glovebox can be released into the glovebox when they need to be replaced, so they can be removed through the Continuous Liner system.

Filters must be selected to specifically match the needs of your process. Ravona offers a selection of HEPA and ULPA filters to trap and filtrate toxics, cytotoxics, and biological materials

. HEPA filters are rated at 99.99% efficient at removing particles down to 0.3 micron, while ULPA filters are rated at 99.999% efficient at removing particles down to 0.12 micron.
