Air Filters

The high pressure filter element ensures reliable filtration with minimal pressure losses:

• Coalescence filter with new, matrix filter-fibre structure
• High efficiency even at low air volumes of only five percent of nominal flow
• Reliable element-to-housing seal
• Stainless steel orifice tubes, oil & acid resistant coated sleeves and end caps

The filter housing that lasts:

• Long service life thanks to the epoxy resin coating inside and out (proven in over 1000 hours of salt contamination tests)
• Easy filter element removal with Kaeser’s O-ring seal system
• Minimal pressure drop due to optimised air flow
• The conical bowl and turbulence-free lower filter zone prevent condensate from being carried along with the air flow
• Audible warning should leakage occur.

The shut off valve allows maintenance of the condensate drain without interrupting air supply

The filter monitor indicates with filter change is required (optional)

• Microprocessor-controlled LCD display
• Comprehensive filter monitoring based on:
  – operating time
  – differential pressure
  – operation efficiency: comparison of increasing energy requirement caused by filter clogging to a maximum value that is dependent on the operating conditions and which is calculated by the monitor
• Significant energy savings
• ‘Filter change’ warning with red LED and alarm contact
• Continuous measurement of pressure differential to an accuracy of 0.025 bar via precision
• pressure transducer
• Direct data input, no separate programming device required

Condensate drainage with the ECO drain (optional) is electronically level-controlled and fully automatic, which means:

• No air losses
• Exceptional reliability
