  • Dynamic Air Quality Solutions - Celebrating Thirty Years!

    This year we are very pleased to celebrate the thirtieth anniversary of the first one-inch polarized-media electronic air cleaner. It was thirty years ago that the first polarized-media electronic air cleaner, produced under our “Dynamic Air Cleaner” brand, was introduced. As with many high-efficiency filtration products, polarized media has its roots in industrial applications. ...

  • Polarized-Media EACs are coming of Age

    Non-ionizing  polarized media is an IAQ technology finding broader market uses. It applies an active electric field to cap tore airborne particles, changing the way particles, behave in the air. In smaller residential equipment, this allows an electronic air cleaner (EAC) to operate efficiently within a space only 1 inch wide - the same sp-ace as a disposable filter. In larger commercial ...

  • Microbial reduction efficiencies of filtration, electrostatic polarization, and UV components of a Germicidal Air Cleaning System

    Abstract: This study determined the effectiveness of components of a germicidal air-cleaning system involving filtration, electrostatic polarization, and UV light on the reduction of airborne bacteria and molds. The filter alone, filter and electrostatic polarization combined, and the filter, electrostatic polarization, and UV light were found to be effective (P < 0.05) in reducing a given ...

  • Air bubbles enhance membrane cleaning: a future perspective

    Abstract Air bubbles generated using a novel micro-bubble generator have displayed a dramatic enhancement in cleaning efficiency when used in conjunction with specially formulated cleaning chemicals. In order to establish the effect of this application on membrane performance, a series of experiments were conducted using both a flat sheet test rig and a small scale pilot plant. ...

  • Visualized study on the interaction between single bubbles and curved solid surface in flotation separation process

    The present study has been devoted to bubble–curved solid surface interaction in water, which is critical to the separation of suspended particles by air flotation. For this purpose, two particular stages of the interaction (collision and attachment) have been examined visually using high-speed photography in a laboratory-scale flotation column. The effects of the surface material and ...

  • Chemical Air Pollution in the Clinical Research Environment

    There has been a revolution in awareness of chemical air pollution in research laboratories. I could tell you several 'horror stories' of casual exposure to mercury vapour, benzene and chromic acid (the ultimate glassware cleaning agent) among innocent biomedical PhD students (including myself) in the 1970s. But researchers in hospitals, and other laboratories can never afford to be complacent ...
