Air purifiers are machines used to purify air in home, aero planes and chemical plants. Air has pollutants such as carbon monoxide, nitrogen dioxide, formaldehyde, and smoke. Ozone and electrostatic air purifier equipped with fan produce less noise and are effective. Ozone is more effective in removing odor. Electrostatic purifiers use electricity to produce positive charge and attract all the negative charged pollutants. Electrostatic precipitation air purifiers produce negative charges and impart them to passing pollutants. The positive plates collectors attract them. However these purifiers are unable to collect allergens because they do not remain air borne for a long time. Once they get settled it is impossible to remove pollutants.

Air Recycling Systems provide closed loop between air compressor and air tool by capturing exhausted air from air tool and returning it to compressor. To reduce energy consumption and noise levels, tool system keeps moisture, dust, oil and pollutants out of compressor and air tools.
