Compressed air filters
The objective of compressed air filtration is to achieve the lowest possible initial pressure gradient. The unique Zephyr technology allows for the initial pressure gradient to be brought down to an astounding 0.07bar. This substantially reduces operating costs due to the lower power input of the compressors and extends the service life of the filter element.
Reliable design
- High-quality bodies and filter elements ensure a low pressure gradient and a long service life.
- The filter includes a pressure gradient indicator allowing the user to easily monitor its operating condition.
- High-quality condensate drains come as standard.
- The filter design facilitates easy servicing.
Energy saving
- The clogging indicator signals when the filter element should be replaced to prevent higher operating costs due to the higher power input of the compressors.
