Harrick Plasma has recently upgraded the PlasmaFlo gas flow mixer accessory (PDC-FMG and PDC-FMG-2) to include more stable, finer control gas flowmeters and a digital vacuum gauge meter. We believe these upgrades will improve the functionality of the PlasmaFlo when used in conjunction with the Plasma Cleaners. For further description, see PlasmaFlo Features.

Harrick Plasma has recently implemented new design changes to the internal electronics and external interface of the basic Plasma Cleaner (PDC-32G and PDC-32G-2). We believe these enhancements will improve the functionality, reliability, and longevity of the basic Plasma Cleaner models.

As part of our continual effort to improve the functionality of our basic and expanded Plasma Cleaner models, a 3-way valve was added to the front cover valve assembly of our Plasma Cleaners, to be used in conjunction with the needle valve.
