AF Series Downstream Filters | ELGi Air Compressor Air Filter

HOW DOES A DOWNSTREAM AIR COMPRESSOR FILTER WORK?

Moisture, particle contaminants, microorganisms, and gases are the most variable components of the atmospheric air. When this air gets compressed, the concentration of these elements increases by 6 to 10 times; that’s why other contaminants like oil and metal traces get added during the compression process. Removing these contaminants from the compressed air before being used for any application is an essential task. This is where ELGi airmate filters come into play.

According to the International Standard, ISO 8573-1:2010, compressed air contaminants like particles, water, and oil are segregated as per purity classes. In this standard, microorganisms and other gases are not included. As a result, the air purity is indicated as [P, W, O] and is ordered as per the number of particles, water, and oil.

ELGi’s AF downstream filters are used in condensed airlines to stop liquids and solid contaminants from entering air compressors. These air compressor filters stop these contaminants from entering the equipment and causing damage. Our filtration grade removes the wet particle from 1 micron to 0.01 micron, aerosols from 0.1 mg/m3 to 0.003 mg/m3 and provides air quality from (2:-:2) to (1:-:1) based on ISO 8573-1:2010 standards. The working principle for ELGi’s Downstream Air Compressor Filter is explained below :

Contaminated compressed air enters the filter through inlet port.
Contaminated air is filtered while coming from inside to outside of filter element.
Large droplets of condensate are collected by element and drained gravitationally.
Collected moisture/water at the bottom of filter bowl is drained out of filter with the help of internal float drain.
Filtered cleaner air is sent out of the filter through outlet port.
For Carbon filter, the flow of air is opposite i.e. inlet and outlet port would change. The contaminated air flows from outside to inside of the filter element, activated carbon absorbs the oil vapour and odor before passing the air through it.
