WILKERSON
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.
