Wilkerson

Wilkerson is a leading American manufacturer of compressed air conditioning equipment for industrial pneumatic systems. As part of Parker Hannifin Corporation, Wilkerson supplies filters, pressure regulators, lubricators, FRL combination units (filter-regulator-lubricator) and silencers for the treatment and conditioning of compressed air in mechanical engineering, automation and process industries. With a catalog of 1,079 products, Wilkerson provides a complete solution for compressed air conditioning from 1/4" to 1" connections.

Wilkerson pressure regulators are the most used products in the range. The 094-03 and 094-04 regulator series precisely controls outlet compressed air pressure from 0.5 to 10 bar at air flow capacities up to 5,000 l/min. Pressure regulators are available in miniaturized versions for restricted space, as lockable models to prevent unauthorized pressure changes, and in high-flow versions for larger pneumatic systems. Pressure gauges are available as options or integrated.

Wilkerson filters remove moisture, oil and dirt from compressed air to 40 micron or 5 micron fine filtration. Auto-drain models automatically discharge accumulated condensate without manual operation. Coalescing filters remove oil mist to 0.01 ppm for food and pharmaceutical applications requiring oil-free air. Filter housings are available in polycarbonate or metal depending on the application.

Wilkerson lubricators add calibrated oil mist to the compressed air stream for lubrication of pneumatic cylinders, air motors and rotary actuators. The lubricators use standard ISO VG 32 lubricating oil and are calibrated to supply 1 drop of oil per 500 l of compressed air at nominal flow. FRL combination units integrate filter, regulator and lubricator in one compact assembly with standard connection rail for quick installation.

At Verkopershulp.nl you will find the complete Wilkerson range including filter element replacements, pressure regulator spare parts, pressure gauges and mounting accessories. Our technical experts advise you on selecting the right conditioning system for your compressed air network and pneumatic installation.

History

Wilkerson Corporation was founded in 1948 in Englewood, Colorado, USA, as a manufacturer of pneumatic conditioning equipment. The company was a pioneer in developing modular FRL units for industrial compressed air treatment. In the 1970s and 1980s, Wilkerson grew into one of the most recognized brands for compressed air treatment in North America. Parker Hannifin Corporation acquired Wilkerson and integrates the brand into its pneumatic division, maintaining the Wilkerson product name for the recognized quality standard in compressed air conditioning.

Frequently Asked Questions

What is an FRL unit and what is it used for? ▾
An FRL unit (Filter-Regulator-Lubricator) conditions compressed air in three steps: the filter removes moisture and dirt, the regulator sets the working pressure, and the lubricator adds oil mist for lubrication of pneumatic components. Wilkerson FRL units are modularly constructed so that individual elements can be replaced or combined. They are installed upstream of pneumatic actuators, cylinders and machine tools.
Which Wilkerson regulator suits my compressed air network? ▾
Wilkerson regulators are available in connections from G1/4 to G1 and flow capacities from 500 to 5,000 l/min. The 094-series is suitable for most industrial applications with regulation accuracies of ±0.1 bar. Choose a model based on the maximum air flow, desired outlet pressure and available mounting space.
How often should I replace the filter element in a Wilkerson filter? ▾
Wilkerson filter element replacement intervals depend on the contamination level of incoming compressed air and operating hours. As a guideline, replacement after 12 months or when pressure loss across the filter exceeds 0.5 bar at nominal flow is recommended. The transparent filter housings allow visual inspection of condensate levels and element contamination.
Are Wilkerson products suitable for food industry environments? ▾
Yes, Wilkerson coalescing filters are specifically designed to remove oil mist to 0.01 ppm residual oil content, required for oil-free compressed air in food and pharmaceutical applications conforming to ISO 8573-1 Class 1. Special versions with NSF-certified materials are available for direct food contact environments.
What is the difference between an auto-drain and a manual drain? ▾
A Wilkerson auto-drain automatically removes accumulated condensate from the filter housing when a certain level is reached, without manual intervention. This is essential for systems running continuously or installed in hard-to-reach locations. Manual drains require periodic condensate release by an operator and are more economical for easily accessible installations.
Can Wilkerson FRL units be expanded with extra modules? ▾
Yes, Wilkerson FRL units are modularly designed with a standard connection rail system allowing extra filter stages, regulators, lubricators and silencers to be added. The modules are connected via a manifold rail that ensures leak-free sealing between units. Conversion between 1/4" and 3/8" connections is possible with connection adapters.
Does Verkopershulp.nl supply spare parts for Wilkerson conditioning systems? ▾
Yes, Verkopershulp.nl supplies replacement filter elements, repair kits, pressure gauges, auto-drain replacements and seal kits for the complete Wilkerson range. For damaged or obsolete components, our technical experts advise on the correct replacement or technically equivalent alternatives.
