The WALKER AC-E0407 replacement filter element is designed for compatible compressed air filtration equipment requiring fine particle filtration and effective residual oil control. Manufactured by Wuxi Yuanmei in Wuxi, Jiangsu, China, this compact element uses activated carbon media, engineering plastic end caps, and Buna-N seals to support consistent filtration performance in industrial air treatment applications.

The element provides a specified filtration precision of 0.01 μm and a residual oil amount of 0.003 ppm. With a processing capacity of 1.0 Nm³/min, it is suitable for compressed air systems operating within the specified flow range. The working pressure range is 0.1–2.0 MPa, while the working temperature range is 1.5–80°C.

Key Advantages

One of the key benefits of the AC-E0407 replacement element is its focus on residual oil control. The activated carbon media is specified for a residual oil amount of 0.003 ppm, providing a clear technical reference for applications where compressed air cleanliness is important.

The element also has a specified pressure loss of ≤0.011 bar. Low resistance across the filtration stage can help maintain efficient airflow and avoid unnecessary pressure demand. Yuanmei indicates potential energy savings of 5–7%, with actual results depending on the complete compressed air installation, operating conditions, and maintenance status.

A service life of up to 8,000 hours provides a useful reference for maintenance planning. However, the actual replacement interval should be evaluated according to operating hours, inlet air conditions, contaminant loading, and changes in system pressure loss.

The compact design is particularly convenient for handling and spare-parts storage. The packaged weight is approximately 0.1 kg, allowing maintenance personnel to keep replacement elements readily available without requiring substantial storage space.

Core Features

The WALKER AC-E0407 replacement filter element corresponds to Yuanmei model YM068060. Its specified dimensions are 47 ±1 mm in diameter and 81 ±2 mm in height, providing measurable references for checking compatibility before installation.

Activated carbon serves as the primary filtration media. This media configuration is suited to applications where controlling residual oil is an important requirement. Engineering plastic end caps provide structural support, while Buna-N sealing components help maintain the required interface between the element and compatible filter housing.

The element has a rated processing capacity of 1.0 Nm³/min. Its operating pressure range extends from 0.1 to 2.0 MPa, and the working temperature range is 1.5–80°C. These parameters allow equipment operators and purchasing teams to compare the replacement element with their existing filtration requirements.

For applications involving non-standard specifications, OEM drawing service is available. Customers can provide technical drawings or dimensional requirements for evaluation, helping Yuanmei determine the appropriate customization approach before production.

Diverse Applications

Laser cutting equipment uses compressed air for various pneumatic and process-related functions. Maintaining appropriate air quality can help protect downstream components from unwanted contaminants. The AC-E0407 element provides fine filtration and residual oil control for compatible compressed air installations used in laser cutting environments.

Electronics manufacturing can also require controlled compressed air quality for suitable production and pneumatic applications. The specified 0.01 μm filtration precision and 0.003 ppm residual oil amount provide measurable performance parameters for buyers assessing filtration requirements in electronics-related facilities.

Sandblasting operations expose compressed air equipment to particulate contamination and demanding working conditions. A suitable filtration stage can help reduce contaminants reaching downstream pneumatic components. The AC-E0407 provides a compact option for compatible equipment where its 1.0 Nm³/min processing capacity meets the required airflow.

User Value & Benefits

Selecting a replacement filter element requires careful attention to more than the original model designation. Buyers should evaluate physical dimensions, media type, processing capacity, pressure range, temperature range, filtration precision, and sealing materials before ordering.

The AC-E0407 provides clearly specified parameters for this evaluation. Its 47 ±1 mm diameter and 81 ±2 mm height make dimensional comparison straightforward, while the 1.0 Nm³/min processing capacity provides a defined airflow reference.

A minimum order quantity of 1 piece gives maintenance teams flexibility when purchasing individual replacement elements. This is useful for scheduled servicing, spare-parts replenishment, equipment maintenance, or small-volume procurement.

Yuanmei maintains a supply capacity exceeding 1,000 pieces, while main models can be shipped within 24 hours. This availability can help reduce procurement delays when standard replacement elements are needed.

For international buyers, the element can be shipped by air through FedEx/DHL or by sea. Standard packaging consists of a plastic bag inside and a paper box outside. Export-standard wooden boxes or pallets can be used for heavy goods, and customized packaging options are available.

Maintenance Tips

Regular monitoring of filter performance helps maintenance personnel identify increasing resistance before it affects compressed air efficiency. Pressure loss, airflow behavior, operating hours, and downstream air quality can all provide useful information when determining replacement requirements.

The specified 8,000-hour service life should be treated as an operating reference rather than a guaranteed replacement interval. Actual service life can vary according to inlet contamination, oil concentration, operating temperature, compressed air demand, and daily running hours.

During replacement, inspect the filter housing and sealing surfaces for dirt, damage, or accumulated contaminants. The new element should be correctly positioned, and the Buna-N seal should sit securely against its designated sealing surface.

Upstream filtration and drainage should also be maintained properly. Reducing excessive contaminant loading before air reaches the element can help support stable filtration performance and extend practical operating life.

Certification & Quality

The product is supplied with ISO8573-1, CE, and RoHS certification marks, providing relevant quality and compliance references for customers evaluating compressed air filtration components for industrial applications.

Yuanmei controls important product specifications during manufacturing to support consistency between replacement elements. Key parameters such as the 47 ±1 mm diameter, 81 ±2 mm height, 0.01 μm filtration precision, and ≤0.011 bar pressure loss provide objective references for product evaluation.

The combination of activated carbon media, engineering plastic end caps, and Buna-N seals establishes a defined material configuration for this model. Buyers can review these specifications together with their equipment requirements before placing an order.
