TGA 6159 Air Filter — order in Moldova (equivalent to Kaeser M27, part no. 6.4163.0)

Technical specifications

Exact dimensions (outer diameter, height, mounting collar diameter) can be confirmed with the supplier at the time of order.

Design features

• Pleated filter media — increases active filtration area without increasing the element’s outer dimensions.
• Direct interchangeability with Kaeser 6.4163.0 — allows TGA 6159 to be used as a drop-in replacement for the original element, with no modification to the filter housing.
• Compact construction — designed to fit the standard air filter housing of the Kaeser M27 compressor without additional adapters.
• Durability under compressor operating loads — the element is sized for the typical operating conditions of screw compressors in this output class.

Installation recommendations

1. Before installation, confirm that the element being replaced actually matches the original Kaeser part number 6.4163.0 — check the markings on the old filter removed from the compressor.
2. Before fitting the new element, clean the filter housing of accumulated dust and remnants of the old gasket.
3. Install the element strictly in the orientation specified by the compressor manufacturer (usually with the pleated side facing outward, toward the incoming air flow).
4. Check the condition of the housing’s retaining spring or fastening assembly — a loosened fixture leads to an improper seal and unfiltered air bypassing the filter media.
5. After installation, make sure there are no gaps between the element’s mounting collar and the filter housing.
6. Replacement frequency is set by the Kaeser manufacturer’s schedule and operating conditions (how dusty the site or facility is) — periodic visual inspection of element contamination reduces the risk of compressor overload.

Comparable solutions

When selecting a replacement, the key factor is an exact match of mounting dimensions and the compressor’s original part number, not just the model name — over the Kaeser M27’s lifecycle, the manufacturer may have used different air filter variants, so it’s recommended to check part number 6.4163.0 directly against the old element removed from the compressor.

Expert comment: the air filter is often the first component that signals a compressor needs servicing — increased intake noise or a noticeable drop in compressor performance is frequently linked to a clogged air filter.

Common installation mistakes

• Replacing the filter without checking the original Kaeser part number 6.4163.0 against the old element — risk of fitting an incompatible part.
• Installing the element without cleaning old dust from the housing — the new filter loses throughput capacity faster.
• Reusing a worn housing gasket — results in an improper seal and unfiltered air intake.
• Ignoring the recommended replacement interval — a clogged element increases intake resistance and reduces the Kaeser M27’s performance.
• Installing the element without regard to airflow direction — reduces filtration efficiency.

Practical use cases

• Scheduled replacement of the standard air filter on the Kaeser M27 compressor during routine maintenance.
• Compressor stations at industrial facilities, auto service centres, and warehouse complexes running Kaeser M27 compressors.
• Repair and refurbishment of compressor equipment — replacing worn filter elements during major overhauls.
• Spare parts stock for service organisations maintaining Kaeser compressors.

Expert opinion

“An air filter is one of the cheapest parts of a compressor, yet it has a major influence on the lifespan of the screw block. For Kaeser M27 compressors, I recommend customers in Moldova keep TGA 6159 in stock as a proven equivalent for original part number 6.4163.0 — this allows the filter to be replaced on schedule without waiting for an original part to arrive,” — Vitali Boluchevski, lead engineer at Acvatron SRL.

FAQ

Does TGA 6159 fit directly in place of the original Kaeser filter, part number 6.4163.0? Yes, TGA 6159 is a direct equivalent by mounting dimensions and is intended to replace original part number 6.4163.0 on Kaeser M27 compressors.

How often should the Kaeser M27’s air filter be replaced? The interval depends on the manufacturer’s schedule and operating conditions (how dusty the site is, how intensively the compressor runs); it’s recommended to follow the compressor’s service manual and periodically inspect the filter visually.

How do I know it’s time to replace the filter? Key signs include increased intake noise, visible contamination of the filter media, and reduced compressor performance.

Can TGA 6159 be used on compressor models other than Kaeser M27? TGA 6159 is selected as an equivalent to part number 6.4163.0 specifically for the Kaeser M27 — for use on other models, it’s recommended to confirm compatibility with the supplier first.

Should the air filter be replaced together with the oil filter and separator? While this is a standalone part, a complete service kit is available for the Kaeser M27 (oil filter, TGA 6159 air filter, separator) — the manufacturer recommends replacing all three components at once during scheduled maintenance.
