The FESTO MS6-LFM-1/2-CIRH:T, Order Number 570522, is a compressed-air fine filter from the MS service-unit platform, intended for applications that require cleaner air, stable pneumatic performance, and a compact but industrial-grade air-preparation format. Reliable distributor listings identify order number 570522 as *MS6-LFM-1/2-CIRH:T and classify it as a fine filter, while FESTO’s current MS6-LFM documentation shows that the MS6-LFM-B family is the size-6 fine-filter platform with 1 μm filtration, fibre-filter design, and G1/2 connection options. In practical terms, that places this product in the category of high-efficiency pneumatic line filtration for machine building, automation, and general compressed-air treatment.
This model is not a pressure regulator and not a lubricator. Its core function is filtration. In a pneumatic system, that matters because contamination in compressed air can shorten valve life, increase actuator wear, damage seals, and reduce the repeatability of machine movements. FESTO’s current MS6-LFM fine-filter data show that size-6 fine filters in this family use a borosilicate fibre filter medium, a 1 μm filtration grade, and are designed to improve downstream air quality while maintaining practical service-unit integration for industrial use.

The exact legacy suffix *CIRH:T is shown in distributor listings for order number 570522, while FESTO’s current published MS6-LFM documentation uses the newer MS6-LFM-B naming logic for size-6 fine filters with 1 μm elements. So the safest technical reading is that 570522 is a legacy or channel-specific fine-filter order code within the MS6-LFM fine-filter family.
Key Technical Characteristics
Because FESTO does not currently expose a public one-page datasheet for 570522 in the same way it does for newer MS6-LFM-B part numbers, the table below combines the exact legacy order-code identification from market listings with the closest current official MS6 G1/2 fine-filter technical reference, namely MS6-LFM-1/2-BRV. That is the most defensible way to describe the product without inventing values that cannot be verified.

| Product Net Weight | 0.735 kg listed for order number 570522; current official comparable MS6 G1/2 fine filters are 600 g or 820 g depending on bowl/guard configuration |
The weight line deserves a direct note. A distributor listing for 570522 gives 0.7340 kg, while FESTO’s official current MS6 fine-filter data show 600 g for MS6-LFM-1/2-BRV and 820 g for MS6-LFM-1/2-BUV. That means the exact 570522 configuration sits plausibly inside the official MS6 family weight envelope, but the 735 g figure itself is from a distributor listing rather than a currently exposed official FESTO datasheet for this legacy code.
Product Design and Functional Value
The MS6-LFM filter platform is built for users who need more than coarse particle separation. FESTO’s current MS-LFM documentation states that the fine-filter variant uses a 1 μm borosilicate fibre element, and that the size-6 version is intended for industrial compressed-air treatment with line installation or accessory-based mounting. In real applications, this means the filter is positioned between basic upstream air preparation and sensitive downstream components such as valve terminals, cylinders, proportional devices, grippers, or precision blow-off circuits. It is especially relevant where contamination control is required but a larger, more complex filtration stage would be unnecessary.
The fibre-filter structure is important because it is not only separating larger solid particles. FESTO’s published data for the current G1/2 fine-filter equivalent show 99% efficiency for fine particles, 90% efficiency for oil aerosol, and a residual oil content of 0.5 mg/m³. These are useful industrial values. They indicate that the product is designed to improve the quality of compressed air meaningfully, not merely to act as a simple moisture trap or line strainer. For automation systems that require longer component life and more stable pneumatic behaviour, this directly supports maintenance reduction and better process consistency.
Flow Capacity and System Integration
One of the more practical strengths of the size-6 platform is that it balances filtration performance with usable flow. FESTO’s official data for the current MS6-LFM-1/2-BRV show a maximum standard flow rate of 950 l/min and a minimum standard flow rate of 140 l/min for the stated clean-air class. For machine builders, that means the filter is not only technically fine enough to improve air quality, but also capable of supporting real industrial pneumatic demand without forcing the system into an oversized service unit. That makes it suitable for machine modules, assembly stations, packaging systems, and automation panels where G1/2 pipework is already part of the layout.
FESTO’s current documentation also states that the MS6-LFM family is designed for in-line installation or mounting with accessories, and that the recommended mounting position is vertical ±5°. This is not a trivial detail. Filtration performance and condensate handling are affected by installation geometry. A correctly mounted fine filter will generally perform more consistently, drain more effectively, and be easier to maintain. In industrial service, these small details often make the difference between a filter that works as intended and one that becomes a maintenance burden.
Materials and Build Quality
The published FESTO material data for the current size-6 G1/2 fine-filter equivalent show a die-cast aluminium housing, borosilicate fibre filter medium, PC bowl, and NBR seals, with RoHS compliance stated in the datasheet. These are mainstream industrial material choices rather than lightweight consumer-grade substitutes. Die-cast aluminium provides a rigid body structure for service-unit integration, while borosilicate fibre is a practical filter material for fine filtration in compressed-air service. This material package is consistent with the product’s intended role as a serious air-preparation component rather than a light-duty accessory.
FESTO also states CRC 2 corrosion resistance and LABS (PWIS) conformity according to VDMA24364-B1/B2-L for the current equivalent. That indicates suitability for ordinary industrial indoor environments with moderate corrosion stress, and it also matters in sectors where contamination sensitivity or finishing-process compatibility can influence component selection. These are not marketing extras. They are the sort of specifications that make a compressed-air filter easier to justify in professional equipment design and more defensible in industrial procurement.
Typical Application Areas
| Application Area | Why This Product Fits |
|---|---|
| Machine Building | Cleaner compressed air for valve islands, cylinders, and pneumatic modules |
| Packaging Equipment | Stable air quality for repetitive, contamination-sensitive cycles |
| Assembly Automation | Fine filtration before precision pneumatic consumers |
| General Factory Pneumatics | Suitable for G1/2 service-unit sections with medium airflow demand |
| Maintenance / Retrofit | Practical replacement option for installed MS6 filtration assemblies |
These use cases are not copied from a brochure headline. They are grounded in the product’s fine-filter role, G1/2 class connection, size-6 body, fibre-filter design, and the official performance window of the current MS6 G1/2 fine-filter reference.
Weight and Selection Notes
For your requirement about product weight, the most accurate statement is this: Order Number 570522 is listed at 0.734 kg by a distributor, while official current MS6 G1/2 fine-filter variants weigh 600 g or 820 g depending on exact bowl/guard configuration. That means a professional listing can include the weight, but it should do so honestly. If you are preparing a website, quotation sheet, or catalog entry, the safest phrasing is “Product weight: approx. 0.735 kg” unless you have the original FESTO package label or manufacturer label for this exact legacy code.
This also has a practical procurement implication. If the buyer needs a direct replacement for an installed legacy *MS6-LFM-1/2-CIRH:T, then the order number 570522 and the exact type marking on the old unit matter more than any generic family description. If the buyer is choosing a functionally equivalent new part for a fresh project, then the current MS6-LFM-B family data from FESTO are the better technical reference. That distinction is important because replacement accuracy and new-project optimization are not the same task.
Conclusion
The FESTO 570522 MS6-LFM-1/2-CIRH:T is best understood as a size-6 G1/2 fine filter within the MS compressed-air preparation platform. Reliable market listings identify the exact order number and model, while FESTO’s current MS6-LFM fine-filter documentation provides the technical framework: 1 μm filtration, fibre-filter construction, 2 to 12 bar operating pressure, G1/2 ports, up to 950 l/min standard flow, and industrial material construction suitable for real pneumatic service.
From a commercial and engineering standpoint, this is a practical industrial filtration component rather than a decorative catalog item. It is suitable where cleaner compressed air is needed to protect downstream equipment, stabilize pneumatic performance, and support longer service life. For listing purposes, you can state the Order Number as 570522, the *Model as MS6-LFM-1/2-CIRH:T, and the weight as approximately 0.735 kg, while noting internally that the exact weight is based on a distributor listing and aligns with the published weight range of current official MS6 G1/2 fine-filter variants.
