WILKERSON

WILKERSON is a brand of compressed air treatment and filtration components, primarily known for its filter-regulator-lubricator (FRL) units and replacement parts. The brand originated in the United States and has been a supplier of pneumatic accessories for industrial applications since the mid-20th century. WILKERSON product families include air filters (particulate, coalescing, and general-purpose), regulators, lubricators, combination units (filter/regulators and FRLs), differential pressure indicators, sight dome kits, and replacement elements. These components are designed for use in compressed air systems where removal of moisture, particulates, and oil aerosols is required to protect downstream equipment such as valves, actuators, and tools. Typical specifications across the line include port sizes from 1/4 in to 1/2 in NPT, flow capacities ranging from 63 scfm to 150 cfm, maximum operating pressures up to 200 psi, and filtration ratings from 0.5 micron to 5 micron. Materials of construction include aluminum bodies, nitrile seals, and bowls in zinc or plastic. The brand offers series such as 08, M18, M28, D18, F16, and F26, each with distinct dimensional and performance characteristics. 3G Electric stocks over 390 SKUs of WILKERSON FRL units and replacement parts, including filters, regulators, lubricators, combination units, and service kits. Inventory covers both current-production models and legacy replacement components. Each SKU is accompanied by datasheets containing dimensional drawings, flow curves, and material specifications. 3G Electric provides logistics support for global shipment, including export documentation and consolidated freight options. For procurement specialists and maintenance managers, the availability of individual replacement parts (such as sight domes, pressure indicators, and filter elements) reduces the need to replace entire assemblies during routine service. The brand's product range is suitable for applications in manufacturing, packaging, chemical processing, and general industrial compressed air networks where consistent air quality and pressure regulation are required.

Frequently asked questions

Common questions about WILKERSON from 3G Electric.

What is the difference between a WILKERSON coalescing filter and a particulate filter?

WILKERSON coalescing filters (e.g., M28-04-BK00B, M18-04-BK00B) are designed to remove oil aerosols and sub-micron particles down to 0.5 micron, using a coalescing media that causes liquid droplets to combine and drain. Particulate filters (e.g., F16-04-000, F26-04-FG0) remove solid contaminants and bulk water at 5 micron, using a mechanical separation element. Coalescing filters are typically installed downstream of particulate filters in a compressed air system.

Can I use a WILKERSON filter/regulator combination unit without a lubricator?

Yes. WILKERSON filter/regulator units such as the B08-02-FKG0B are standalone components that provide filtration and pressure regulation. They can be used without a lubricator if the downstream equipment does not require oil mist lubrication. For applications that need lubrication, a separate lubricator (e.g., from the D18 series) can be added downstream.

What is the maximum operating pressure for WILKERSON FRL units with zinc bowls?

WILKERSON FRL units with zinc bowls, such as the F26-04-FG0 particulate filter, are rated for a maximum operating pressure of 200 psi. Units with plastic bowls, like the F16-04-000, have a lower maximum of 150 psig. Always verify the specific model's rating on the datasheet before installation.

How do I identify the correct replacement sight dome kit for my WILKERSON FRL?

WILKERSON sight dome kits are identified by manufacturer part numbers such as LRP-95-239. To find the correct kit, match the model number of your existing FRL unit (e.g., L17-04-D00) with the compatible kit listed in the product documentation. The kit includes the transparent dome and sealing components for visual oil level monitoring.

What is the flow capacity of a WILKERSON 1/2 in NPT coalescing filter?

A WILKERSON 1/2 in NPT coalescing filter, such as the M28-04-BK00B, has a flow capacity of 72 cfm at 100 psi inlet pressure. The M18-04-BK00B, also 1/2 in NPT, is rated at 85 cfm. Actual flow depends on inlet pressure and allowable pressure drop; refer to the flow curve on the datasheet for your specific operating conditions.

Are WILKERSON replacement parts interchangeable across different series?

No. WILKERSON replacement parts such as filter elements, seals, and sight domes are specific to each series (e.g., 08, D18, M28, F16). For example, a differential pressure indicator DP2-01-001 is designed for use with specific filter housings. Always use the manufacturer part number listed for your unit to ensure proper fit and performance.
