Kaeser compressed air filters

Kaeser Compressors has launched an updated generation of compressed air filters that it says provide highly efficient filtration for flow rates from 0.6 to 32.0 m³/min.

The efficiency of a compressed air filter depends most on pressure loss, with every 1 bar of pressure loss increasing a user’s energy cost by 6% per m³/min of compressed air. Kaeser says its filters deliver a 50% lower pressure loss and that it remains constant throughout the entire service life of the filter element. As a result significant cost reductions and reduced CO₂ emissions are made possible.

Kaeser filters use filter elements with flow-optimised element heads. The filter inlet is offset towards the air inlet, which increases the flow cross-section at the air discharge side and contributes to higher filter efficiency with minimal pressure loss. Generously dimensioned connection flanges also help to keep pressure losses to a minimum.

High filtering efficiency with minimal pressure loss is also assisted by the element head of the filter, which is optimised for best possible air flow. Its tapered internal structure channels the compressed air towards the centre of the element interior for an even charging of the filter media.

In addition, deep pleated particulate and coalescence filter elements feature large filter surfaces, further increasing efficiency.
