WILKERSON

Wilkerson is a manufacturer of compressed air treatment and pneumatic control equipment, with a product history that dates back to the mid-20th century. The brand is known for its FRL (Filter-Regulator-Lubricator) product families, which include air filters, pressure regulators, filter/regulators, lubricators, and a broad range of replacement parts. Wilkerson products are used in industrial compressed air systems to remove contaminants, stabilize downstream pressure, and introduce lubrication where required. The line spans modular and non-modular designs, with port sizes from 1/4 inch to 2 inch NPT and flow capacities from under 70 scfm to 1,600 scfm. Many units are constructed with zinc bodies and nitrile seals, and are rated for maximum operating pressures up to 300 psig. Filtration options include 5-micron elements, and adjustment mechanisms range from non-rising knobs to dial-type regulators. The product catalog also includes panel-mounting nuts, O-ring kits, valve kits, and other service components that support maintenance and repair of installed FRL assemblies. 3G Electric supplies the Wilkerson line as part of its industrial equipment distribution portfolio. The current offering includes 396 SKUs, covering regulators, filter/regulators, replacement parts, and mounting hardware. Each SKU is listed with manufacturer part numbers, key specifications, and country-of-origin data where available. 3G Electric serves plant engineers, maintenance managers, and procurement specialists who need to specify or replace components in existing compressed air systems. The company provides datasheets, logistics support, and quotation services for Wilkerson products, with global shipping capabilities. For buyers, the Wilkerson line offers a range of port sizes and flow capacities to match specific pneumatic system requirements. The availability of replacement parts such as O-ring kits and valve kits supports ongoing maintenance without requiring full unit replacement. Panel-mounting nuts and other accessories allow for secure installation in control panels and machinery. 3G Electric maintains inventory and sourcing channels for these components, helping to reduce downtime when replacements are needed. The brand's focus on standardized connections and modular components simplifies integration and servicing across different system configurations. Technical documentation, including flow curves and pressure ratings, is available for most catalog items, allowing engineers to verify compatibility before purchase. 3G Electric's role is to make this catalog accessible to industrial buyers worldwide, with responsive quoting and order fulfillment.

Frequently asked questions

Common questions about WILKERSON from 3G Electric.

What is the maximum operating pressure for Wilkerson FRL air regulators?

Many Wilkerson FRL air regulators, such as the R21 and R31 series, are rated for a maximum operating pressure of 300 psig. This rating applies to the regulator body and internal components under specified temperature conditions. Actual working pressure should be determined based on system requirements and the pressure rating of downstream equipment. Always consult the specific product datasheet for exact limits, as ratings can vary by model and seal material.

What port sizes are available in the Wilkerson FRL air filter/regulator line?

Wilkerson FRL air filter/regulators are available with port sizes ranging from 1/4 inch to 2 inch NPT. For example, the 6 Series filter/regulator (CB6-02-000) uses 1/4 inch NPT ports, while larger regulators like the R41-0C-000 have 2 inch NPT connections. Flow capacities vary accordingly, from 70 scfm to 1,600 scfm. The appropriate port size depends on the airflow requirements and the existing piping in the compressed air system.

What replacement parts are available for Wilkerson compressed air treatment units?

3G Electric stocks a range of Wilkerson replacement parts, including O-ring kits (e.g., GRP-95-260) and valve kits (e.g., RRP-96-684). These kits are designed to service specific models and series, such as the R21, R11, and 5GC16. O-ring kits maintain seal integrity in filtration and regulation equipment, while valve kits restore or maintain valve function. Using genuine replacement parts helps ensure proper fit and performance. Always verify compatibility with your exact model number before ordering.

What is the filtration rating of Wilkerson FRL air filter/regulators?

Wilkerson FRL air filter/regulators, such as the 6 Series (CB6-02-000), typically provide 5-micron filtration. This rating indicates the ability to remove particulate contaminants down to 5 micrometers in size. The filter element captures solid particles and some liquid aerosols, protecting downstream components from wear and contamination. For applications requiring finer filtration, additional coalescing or high-efficiency filters may be needed. Always check the specific product datasheet for the exact filtration rating and flow characteristics.

Are Wilkerson panel-mounting nuts compatible with all FRL units?

Wilkerson panel-mounting nuts, such as those in the RPA series (e.g., RPA-96-734 and RRP-96-676), are designed for specific FRL series and mounting configurations. They are not universal. Compatibility depends on the thread size and the design of the regulator, filter, or lubricator being mounted. These plastic nuts provide secure fastening to panels or mounting surfaces and offer corrosion resistance. Always cross-reference the mounting nut part number with the intended FRL model to ensure proper fit.

What is the flow capacity range of Wilkerson air regulators?

Wilkerson air regulators cover a wide range of flow capacities, from approximately 70 scfm for smaller units like the 6 Series filter/regulator to 1,600 scfm for large regulators such as the R41-0C-000. Intermediate models include the R21-03-000 at 180 cfm and the R31-06-000 at 400 scfm. Flow capacity depends on port size, orifice diameter, and pressure drop. When selecting a regulator, consider the required flow at the desired downstream pressure to ensure the unit can handle the demand without excessive droop.
