Portable air clean unit for industrial and cleanroom applications

GE Technology Inc. (Getek) has launched the ACU portable air clean unit. ACU combines high-efficiency particulate control with customisable molecular filtration in a self-contained mobile unit, delivering a solution for indoor air quality and controlled-environment contamination control in both commercial and industrial settings.

Unlike conventional portable air cleaners, which are limited to HEPA filtration and generic carbon media, the unit offers ULPA-class particulate options for beyond-HEPA performance and refillable, site-specific CHEMSORB chemisorptive blends. This combination targets airborne molecular contaminants (AMC) that standard design/absorbents cannot address, while reducing consumable waste and supporting ESG objectives.

The mobile design allows fast relocation to address localised contamination wherever it occurs. Air enters from the bottom, moves vertically through the unit, and exits from the top for efficient air distribution. Four casters, including four locking wheels, provide for easy movement and secure placement. Configurations can vary from general ambient air cleaning to ultra-high filtration for cleanrooms and critical production areas.

ACU supports HEPA H13 and optional ULPA stages, delivering up to 99.999% particle removal efficiency at MPPS. This makes it suitable for occupational health protection, reducing infection risk, and ensuring process-critical cleanliness.

The lower chamber houses Getek CHEMSORB media in refillable trays (CHEMSORB-R), pleated (CHEMSORB-P), or sponge (CHEMSORB-S) formats. Depending on the blend, CHEMSORB targets acids, bases, molecular gases, VOCs, ozone, reactive compounds, and boron-/phosphorus-containing gases.

The ACU is ideal for applications including commercial and Public Spaces, Industrial and Manufacturing, Cleanroom and Process-Critical Environments. The ACU is positioned as an IAQ supplementation solution and is not a medical device. No pathogen-reduction claims beyond filtration performance are intended.
