About the 6.4143.0 air filter

The 6.4143.0 is Kenrax's direct replacement air filter for Kaeser compressor service. Kaeser compressors are engineered around low energy consumption, and a visibly loaded filter inside the design pressure drop is part of how that efficiency is maintained. Rather than a generic 'fits most' element, it is built to the specific performance envelope of the machine it replaces.

Enhance the performance and longevity of your Kaeser compressors with our high-quality Air Filter Cartridge (Part Number: 6.4143.0). Designed to meet or exceed OEM specifications, these Air Filter Cartridge ensure optimal efficiency and reliability. Specifically engineered for Kaeser compressors, they provide superior filtration, protecting your equipment from contaminants and wear. Each Air Filter Cartridge undergoes comprehensive quality control to deliver consistent and dependable performance. Benefit from competitive pricing, bulk order discounts, and prompt delivery for all your compressor spares.

What the 6.4143.0 does in your Kaeser compressor

The air filter is the compressor's intake guard. It removes dust and particulate from ambient air before it reaches the rotors, bearings, and oil system. In a screw compressor the clearances between rotors and housing are measured in thousandths of a millimetre — abrasive dust that bypasses the filter gets pinned between those surfaces and scores them. The filtration media must handle the machine's full intake airflow while presenting a minimal pressure drop, because every extra bar of intake restriction is paid for twice: once in energy, once in heat.

The 6.4143.0 is a scheduled-service consumable, not a repair item. Fitted as part of the Kaeser machine's standard maintenance, it keeps the Kaeser compressor inside its design operating band between services.

When to replace this element

• Clean environments: 2000–4000 operating hours, or per the OEM manual.

• Dusty or industrial environments: inspect every 500–1000 hours and change on condition.

• Always change earlier if the element shows loading, damage, or if the filter restriction alarm activates.

Signs it needs replacement

Replace on any of the above regardless of hour count. For this part, keeping a fresh element in stock before the interval arrives is the single cheapest insurance policy on the machine.

• A dark, clearly loaded or visibly dusty element when compared with a new one.
• Rising intake restriction shown on the compressor controller or a differential pressure gauge.
• Higher discharge temperature, because a starved intake forces the rotors to work harder.
• Reduced output flow or pressure at the point of use.

Fitting and verification

• Isolate and depressurise the compressor before opening the housing.

• Remove the old element and compare dimensions and gasket profile against the new one before installing.

• Clean the housing and intake pipe interior so no debris falls into the air end.

• Seat the element squarely, rock it gently into place, and confirm the housing seals firmly.
