Kaeser Air Filter 6.3528.0

The Kaeser Air Filter 6.3528.0 is an air filter cartridge designed for applicable Kaeser compressor and vacuum-system applications. Kaeser parts documentation identifies 6.3528.0 as an air filter cartridge, while other technical references describe the part as an air intake filter. Public parts data also associates the part with selected Kaeser models including the M20, M21, M22, M24, M25, M26, M31, M43 and M50, as well as selected vacuum systems.

The filter works at the intake side of the equipment. It removes dust, dirt and airborne particles before contaminated air reaches internal components. This basic filtration function helps the compressor maintain clean airflow and supports dependable operation.

Protect the Compressor From Intake Contaminants

Every compressor draws surrounding air into its intake system. That air can contain dust, dirt and other airborne particles, particularly in industrial environments.

The 6.3528.0 air filter cartridge captures these contaminants before they enter the compressor. This helps reduce the amount of foreign material reaching sensitive internal surfaces.

Clean intake filtration supports better equipment protection and contributes to consistent compressor operation.

Maintain Clean Intake Air

The air filter directly influences the quality of air entering the compression system.

A loaded or damaged filter can restrict airflow and increase pressure drop. A correctly maintained filter helps the compressor receive the airflow it requires under normal operating conditions.

For this reason, technicians should inspect the intake filter as part of planned compressor maintenance.

Support Efficient Airflow

A clean air filter allows the intake system to operate with less restriction than a heavily contaminated filter.

When dust accumulates on the filter media, airflow resistance can increase. This can affect compressor operating conditions and may increase the effort required to draw air into the system.

Replacing the filter when required helps maintain the intended intake path.

Help Protect Internal Components

Dust and airborne contaminants can contribute to contamination and wear when they enter compressor equipment.

The Kaeser 6.3528.0 helps intercept these particles before they reach internal components. This makes intake filtration an important part of routine compressor protection.

Regular filter inspection also gives technicians an opportunity to identify excessive dust loading or unusual contamination around the intake system.

Check the Correct Kaeser Application

Do not choose an air filter based only on its physical appearance.

The 6.3528.0 appears in multiple parts references and applications. Public cross-reference data lists it for several Kaeser models and also shows a 6.3528.0/A1 variant.

Kaeser documentation also shows 6.3528.0 in specific equipment parts lists, demonstrating that the correct application depends on the equipment configuration.

Always check the machine nameplate and parts documentation before ordering.

Verify the Part Number Before Ordering

The exact part number provides an important starting point for filter identification.

For this product, verify:

• Brand: Kaeser
• Part Number: 6.3528.0
• Part Type: Air filter cartridge
• Application: Applicable Kaeser compressor/vacuum systems
• Existing filter number
• Compressor model
• Machine serial number

Kaeser documentation specifically recommends providing the compressor model, serial number, part name and order number when making spare-parts inquiries.

Understand the 6.3528.0/A1 Reference

Some aftermarket and cross-reference databases list 6.3528.0/A1 alongside 6.3528.0. SF Filter, for example, lists both numbers as Kaeser air-filter references.

However, customers should not automatically assume that every suffix or aftermarket cross-reference applies to every machine.

Use the exact part number shown in your compressor documentation or confirm the replacement against the machine model and serial number.

Inspect the Air Filter During Maintenance

Technicians should inspect the air filter at appropriate service intervals and consider the operating environment.

Dusty workshops, construction areas and other contaminated environments can load filters faster than cleaner facilities.

During inspection, check for:

• Excessive dust accumulation
• Damaged filter media
• Deformation
• Poor sealing
• Contamination around the filter housing
• Unusual airflow restriction

Replace the filter when its condition or the manufacturer’s maintenance procedure requires it.

Avoid Excessive Filter Restriction

A heavily loaded filter can restrict the compressor’s intake airflow.

Reduced airflow can affect compressor operation and may contribute to increased pressure drop across the intake system.

Maintaining the correct filter therefore supports both filtration and airflow.

The goal is not simply to install a filter; the goal is to maintain the intake system in the condition required by the compressor manufacturer.

Support Reliable Compressor Maintenance

Air filters form part of a broader compressor maintenance program. Technicians should inspect the air filter together with other service components such as oil filters, oil separators, belts, valves, coolers and condensate-management components where applicable.

Replacing the correct filter at the appropriate service interval helps maintain a consistent maintenance routine.

A correctly identified 6.3528.0 air filter cartridge can therefore serve as an important replacement component for applicable Kaeser equipment.

Choose the Correct Replacement Filter

When purchasing a replacement, compare the existing filter with the required part information.

Public references describe the 6.3528.0 as an air filter/air intake filter and list dimensions around 115 × 253 mm.

These dimensions can help with identification, but they should not replace model and serial-number verification.

Always prioritize the equipment manufacturer’s parts information when confirming fitment.
