Best-in-class ten-year warranty for housing
The common problem with most housing is corrosion. While this corrosion doesn't affect the filter's performance itself, it adds particles of its corroded body (Al or Fe) to the air, thus making it unfit for sensitive applications. With this warranty, customers can have a reliable, pure operation for the entire life of the filter.
Compact and space-saving
High-capacity filters with dual filter housing reduce space consumption and are compact compared to the fabricated filters.
Differential pressure gauge & filter status indicator
Three colored range on indicator helps identify filter element actual condition and plan the maintenance activity efficiently.
In-built service indicator
Helps alert the user for on-time maintenance and service.
Automatic internal float drain
Automatically removes maximum condensate from the system with minimal air loss and saves the element from being soaked, avoiding moisture/ water carryover to the downstream equipment.
High Safety Norms and certification
Filters are CE, AS, CRN, ASME certified and made under ISO quality standards and iuta verification for high performance.
Zero loss drain option
Only the Condensate is dehydrated with an external level sensing drain. There is no air loss (energy saving). Both mechanical and electronic drain options are available with ELGi's Downstream filters.
Wall mounting kit & clamp option
Wall mounting kits are available to easily connect the filters to the wall. The clamp provided attaches two filters easily without any pipes.
Moisture, particle contaminants, microorganisms, and gases are the most variable component 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.
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. They 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.
