Compressed air filter = air quality!
In 100 m³ of compressed air from a prosperous "compressor" that is in a well-ventilated and clean room is about 2.2 liters of water (75% liquid and 25% vapor), 2 grams of oil and approximately 8 million dirt particles of varying size the compressor sucked in through its rough intake filters.
QF - filters remove particles larger than 5 micron.
PF - filters remove particles larger than 1 micron.
hF - filters remove particles larger than 0.01 micron (technically oil-free air)
.CF - filter takes the "aromatics" and particles larger than 0.006 Micron, this is necessary primarily for applications where air must be taste-and odorless.
The filter cartridge fitness is measured by the pressure drop across the filter is measured - the more clogged filter, the greater the pressure drop.Models with one in the last letter, such as QFI, the indicator for reading the pressure drop across the filter.Models with an M as the last letter, such as QFM, the gauge for more accurate reading of the pressure drop.
The filter elements should be replaced after a maximum of 2000 hours!
Each filter can handle 16 bar
