Compressed Air TreatmentView all
Air Line Lockout Valves 
Air Regulators They reduce supply pressure to the level required for efficient operation of downstream pneumatic equipment. They are used for material handling systems, flow & temperature controllers, critical air control circuits and valve positioners. These units feature a rising / non-rising knob that can be adjusted as per user requirements.
Coalescing Filter Elements They are used for separation of two phases, such as removal of water aerosols & droplets from gas (down to 0.01 micron). Two filter element grades are offered with these units to meet air quality requirements.
Compressed Air Filters Compressed air line filters are used to remove contaminants from compressed air. They improve quality and control the flow of compressed air to help pneumatic equipment operate properly. These compressed air filters clean airflow by trapping dirt, moisture & other impurities and monitor air pressure exiting the compressor.

Desiccant Dryers 
Electronic Proportional Regulators These regulators provide very fast response times & accurate output pressure. They are equipped with LED displays for indicating output pressure and offer selectable I/O parameters. They allow no air consumption in steady state with full flow exhaust and feature IP65 rated protection.
Filter Regulator Lubricators (FRL) 
Filter/Regulators These filter regulators combine an air filter and a regulator in a single unit. They are designed to remove solid & liquid contaminants from air and provide controlled & consistent air pressure. The large diaphragm is suitable for valve area ratio. These units provide high flow capacity and meet NACE Specification MR-01-75 / ISO 15156.
General Purpose Filter Elements General purpose filter elements remove water and particulate matter from the air stream to protect downstream equipment from contamination. They are designed for the removal of solid particle contaminants down to 5 microns and for separation of bulk liquids. These units can also be used as a prefilter for coalescing (oil removal) filters.
Oil Removal Filters Oil removal filters from Wilkerson are designed for the removal of solid particles, water and oil aerosols down to 0.01 micron. They contain two filter element grades for better air quality.
Pneumatic Condensate Separators Feature a centrifugal airflow pattern to remove large particulates from the compressed air stream. Models with auto-drain facility also available
Pneumatic Lubricators Zinc / stainless-steel lubricators used to introduce airline oil into the compressed air system even under pressure. Feature an integrated full-sight dome assembly. Modular versions with adjustment knob also available
Pneumatic Modular FRL Accessories Includes mounting nuts, end block connectors, joiner sets, drains, brackets and nuts required for the installation of pneumatically operated Wilkerson filters, regulators and lubricators
Pneumatic System ComponentsView all
Pneumatically Operated Drain Valves Aluminium / zinc auto-drain valves used to regulate the flow of contaminants automatically from the filters. Compatible with 1 / 2 and 3 / 8 inch NPT pipes and can bear fluid pressure up to 200 psi

Parts The brand offers multiple parts including lubricator bowls, filter bowls, pressure indicators, dial air regulators and sight dome kits to enhance the performance of Wilkerson filters.
About Wilkerson
The extensive Wilkerson catalogue includes regulators, filters, air dryers, lubricators and filter elements. Wilkerson non-rising air regulators are suitable for services requiring uniform pressure and variable flow rates. These Wilkerson regulators, with an adjusting knob, are capable of being monitored remotely with the help of small pilot regulators. They feature brass / zinc alloy construction to ensure corrosion resistance and deliver airflow rates up to 100 cfm. Wilkerson pressure regulators (R28 Series) decrease the air line pressure to required levels between 0.2 and 17.2 bar. These Wilkerson regulators have a balanced valve design & a spring-loaded diaphragm that can facilitate reverse flow as well. Wilkerson compressed air filters are designed to protect filtration equipment by removing dust, oil and moisture. These compact Wilkerson filters feature a standard filtration mechanism having a 5-micron rating, a 1/2 inch NPT / BSPP-G over-port for effective sealing and quick-disconnect bowls for preventing accidental disconnection. The polycarbonate bowls on these Wilkerson filters have an integrated guard / metallic wire with a sight gauge for ensuring durability. They can withstand temperatures & pressures up to 150 degrees Fahrenheit & 250 psi, respectively. Choose from a wide range of these Wilkerson products, along with pneumatically operated drain valves and filter regulator lubricators, on Raptor Supplies.

Frequently Asked Questions
How does an airflow regulator work?
Airflow regulators have a spring-actuated valve which is directly regulated by a diaphragm assembly. Pressure or energy from the flowing medium activates the diaphragm, and the increasing downstream pressure falls on the diaphragm, thereby closing the valve plug by compressing the spring.
What is the function of the auto drain in Wilkerson pneumatic separator condensers?
Wilkerson pneumatic separator condensers have an auto drain for automatically removing dirt and condensate.
What is an FRL regulator?
An FRL unit combines a filter, regulator and lubricator into a single component for keeping air compressor systems in excellent working condition.
When should I use an AtoMist lubricator instead of an EconOmist Lubricator?
AtoMist lubricators send finer oil aerosol particles downstream, than EconOmist lubricators. These oil particles remain suspended in the airstream for a longer duration than the larger EconOmist droplets.
When should I change my coalescing filter?
Usually, coalescing filters are changed when the change-out pressure varies from 8 to 10 PSI.
What are some safety instructions to remember while installing Wilkerson air regulators?
- These Wilkerson air regulators should be installed very close to the point of use.
- A particulate filter should be installed on the inlet side of a Wilkerson air regulator for decreasing maintenance requirements.
- These regulators have a flow arrow to indicate the direction of flow.
- Users should use pressure gauges in the auxiliary ports, else block the unused port using pipe plugs.
- Attachments like reducing bushings & couplings should not be installed with this product. They restrict air flow and reduce performance.
