Why choose an electrostatic, washable air filter?

When deciding what type of air conditioner or furnace filter to use, you should keep two things in mind: Airflow and Efficiency. In order to work at its optimum level, the a/c or heating unit requires no restriction to air flow. You should choose a filter that has the least effect on airflow, but removes the most dust from the air. ACI’s electrostatic air filters allow the air conditioning ...

Wet electrostatic precipitators: A preferred technology for emission control

The basic science behind electrostatic precipitators is as familiar and as simple as static cling. But today, this elemental force has been harnessed to a technology that is helping to remove millions of tons of toxic chemicals from our atmosphere; saving billions of dollars annually in pollution-related physical damage; and averting costly impacts on health and mortality rates for millions of ...

Non-woven electrostatic media for chromatographic separation of biological particles

The filtration and separation of biological particles has been estimated as 40% of the cost in the manufacture of pharmaceuticals. Liquid chromatography that is the principal method for separating biological particles uses a permanent phase of ultrafine adsorbent particles such as porous silica or resin spheres with particle sizes down to about 1 micron. Speed and resolution are two competing ...

High efficient cyclone systems with electrostatic recirculation for particulate matter (PM) emission control

The development of new optimized dedusting systems has particular and increasing relevance for atmospheric particulate emission control. Indeed, traditional "particulatetraps" present several disadvantages that foster the search for alternative solutions. Industrial cyclones are, for their robust construction, absence of moving parts and general application, an appropriate technology for emission ...

Can protective garments be wearable filters?

Protective garments for medical, civilian safety and military applications range from disposable lightweight fabrics to multilayered fabrics and laminated barrier materials, depending upon the nature of the contamination that threatens the wearer. Usually, only full barrier garments, such as the Level A liquid splash protective garments provide full protection from aerosols, and this is due to ...

Cigarette smoke: size distribution and effects on filters

Cigarette smoke is an important aerosol in the air filtration industry and research. It is an unwanted aerosol and therefore there are many applications for air filtration (ex. cigarette filters, residential and commercial ventilation filters, home air cleaners). Cigarette smoke is especially important to air filter performance for several reasons. First, the size of cigarette smoke particles ...

Electrofilter protection by fast monitoring of CO in flue gas – Case Study

Electrostatic precipitators Many industrial operations produce exhaust gases that contain dust, fly ash (unburned constituents), fumes (including fine elemental particles such as cadmium, sulfur and lead) and mist (such as coal tar), which cause an unwanted impact to human health and the environment. One widely used method of removing such contaminants from a gas stream is to use an ...

Suffer from Allergies or Asthma?

The “ULTRA” washable air filters have an antimicrobial protection that will not allow bacteria, fungi or mold to grow on the filter surface. The antimicrobial protection is not a coating and is not sprayed on. It is a safe and effective antimicrobial agent processed directly into the electrostatic fiber media, rendering it as permanent as the filter itself. The University of ...
