Prevost Filter Regulator

Prevost Filter Regulator

The Prevost Filter Regulator is a compact, shop-ready compressed air filter regulator built for point-of-use air preparation, pressure control, and basic particulate protection in pneumatic air systems. Designed for use in compressed air lines feeding tools, workstations, and general air-powered equipment, this Prevost air line filter regulator combines two essential functions in one unit: filtering incoming air and regulating outlet pressure before the air reaches the application.

This is the correct product family for Prevost ATU M2585200, ATU M2585201, ATU M2585202, and ATU M2585203, with available NPT sizes from 1/8" through 1/2". The Warthog listing offers four size/flow options, ranging from 25 CFM to 159 CFM at 87 PSI, depending on the selected port size.

Clean, Controlled Air for Pneumatic Equipment

Compressed air can carry scale, dust, moisture droplets, and other contaminants through the piping system. It can also arrive at a workstation at a higher pressure than the tool or process requires. The Prevost Filter Regulator helps solve both issues by filtering to 25 microns while allowing the outlet pressure to be adjusted for the job.

Prevost’s official technical documentation lists this filter-regulator with a maximum operating pressure of 145 PSI, an adjustable outlet pressure range of 7.3 to 123.3 PSI, 25 micron filtration, and a working temperature range of 41°F to 122°F.

Available Models and Flow Ratings

1. ATU M2585200
   1/8" NPT female thread with 25 CFM flow rate at 87 PSI.
2. ATU M2585201
   1/4" NPT female thread with 35 CFM flow rate at 87 PSI.
3. ATU M2585202
   3/8" NPT female thread with 106 CFM flow rate at 87 PSI.
4. ATU M2585203
   1/2" NPT female thread with 159 CFM flow rate at 87 PSI.

Prevost’s product sheet lists these flow ratings at 87 PSI with a 14.5 PSI pressure drop. The smaller 1/8" and 1/4" versions have a listed body dimension of 1.57" x 8.46", while the larger 3/8" and 1/2" versions measure 2.44" x 11.89".

Built for Workstation Air Control

This Prevost compressed air filter regulator is a strong fit for workstations where air pressure needs to be controlled close to the point of use. Installing a filter-regulator near the air drop helps keep pressure adjustments accessible and helps reduce contamination before air enters downstream pneumatic equipment.

Common uses include:

• Assembly benches
• Maintenance workstations
• Pneumatic tool stations
• General shop air drops
• Small production areas
• Repair bays
• Industrial work cells

The 25 micron filtration rating makes this unit suitable for general particulate removal and everyday compressed air preparation. For applications requiring ultra-dry air, oil vapor removal, breathing air, instrumentation air, or high-purity process air, additional air treatment may still be required upstream or downstream depending on the air quality target.

Why Use a Filter Regulator?

A filter regulator is one of the most practical accessories in a compressed air system because it improves both air cleanliness and pressure control at the same location. Instead of installing a separate particulate filter and pressure regulator, this single Prevost unit combines both functions in a clean, compact assembly.

Benefits include:

• More consistent tool performance
• Reduced risk of debris reaching pneumatic components
• Easier pressure adjustment at the workstation
• Cleaner installation compared with separate components
• Better control over air consumption and operating pressure
• Protection for downstream tools and accessories

Using the right pressure matters. Too much pressure can increase air consumption, wear out tools faster, and create unnecessary stress on fittings and hoses. Too little pressure can cause poor tool performance. The Prevost Filter Regulator gives the operator a straightforward way to dial in usable outlet pressure while maintaining basic filtration.

Compact Prevost Quality for Compressed Air Systems

Prevost is known for compressed air connection, distribution, and air treatment components used in industrial and shop environments. This filter regulator fits that same purpose: reliable air preparation in a compact package that can be matched to the air demand of the line.

Choose the 1/8" or 1/4" model for lower-flow tool drops and smaller pneumatic connections. Choose the 3/8" or 1/2" model when the application requires higher flow capacity. Each option keeps the same core function: filter the air, regulate the pressure, and give the workstation a cleaner, more controlled air supply.

For shops, service departments, and production environments that need a dependable air line filter regulator, the Prevost Filter Regulator is a simple, proven solution for point-of-use compressed air control.
