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 systems, it can mean high levels of air quality with reduced operating costs.
How to Choose the Right Commercial Air Filter
When it comes to selecting a commercial air filter, or air filtration system, there are many variables that have to be considered. In general, the choice of which air filter can be made a bit easier by first defining the overall goal that you are trying to achieve which is usually one of two options. Is the purpose of the filter to protect the air circulation equipment, or is it to provide a better environment for the occupants of the building? Different air filters in different systems serve — you guessed...
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. Although the first electrically enhanced air filters date back to 1930, it wasn’t until 1982 that two professors from...
Achieving a cleaner, more sustainable and healthier future
In 2009, as countries prepared to negotiate a global climate treaty in Copenhagen, Denmark, the front cover of the firstLancetCommission on health and climate change issued a stark warning: “Climate change is the greatest health threat of the 21st Century”. This warning was not heeded: the overall agreement fell short of the necessary ambition, and health was noticeable by its absence from the negotiations. However, over the longer term, the Commission made its mark, contributing to a gradual but...
A Cleaner Energy Future
As renewable energy plays an increasingly important role in the world’s energy portfolio, the standards of ASTM International Committee E44 are helping to pave the way for innovation in clean energy sources. A growing population and improving living standards around the world are causing significant increases in energy demand and competition for fossil fuels. These escalating energy requirements are converging with diminishing fuel resources, resulting in a ripple effect throughout our global economy and...
Large Area Hard Floor Cleaners with Reduced Noise
Contractors are often hired to maintain cleanliness in and around hospitals, residential areas, nursing homes, schools, public libraries, and similar places. However, using conventional hard floor cleaning machines could have one drawback, the high noise levels. Therefore, contractors use machines designed to operate with reduced noise. The volume of sound generated by advanced large area hard floor cleaners is around 58 decibels. In addition to lower noise working, these machines have many other advantages that...
