Pre-filters and afterfilters
Some applications may require an additional stage of filtration. Infinity filters can be installed with pre-filters and afterfilters, depending on the nature of the installation.
Pre-filters contain an integral tray holding a sheet of filtration material or metal mesh which can be washed or replaced. They can be used to protect the Infinity unit where this is a heavy contamination level, such as in grinding applications.
Afterfilters are designed to remove oil smoke and any residual fine mist particles (below 0.5μ) which may not have been fully captured by the Infinity.
