Frequently Asked Questions

Is the 02250151-201 blowdown valve compatible with my Sullair compressor?

The 02250151-201 part is consistently listed across multiple compressor parts suppliers as a Sullair pressure regulator / blowdown valve manifold for select 185-series portable compressor applications. Compatibility should always be confirmed by matching the exact part number in the machine’s parts manual or by verifying with the compressor’s model and serial number before ordering. Not sure? Reach out with your compressor model and serial number and we’ll help confirm compatibility.

What does a blowdown valve do?

A blowdown valve helps release internal pressure from the compressor system during unloading or shutdown. In compressed air systems, blowdown components are used to release excess air or internal pressure at specific stages of operation, which helps support proper system performance and protect compressor components.  

Why is it important to replace a faulty blowdown valve?

A faulty blowdown valve can interfere with how the compressor unloads and relieves pressure, which may affect restart behavior and overall system operation. Because blowdown valves are part of the system’s pressure management process, replacing a worn or malfunctioning unit helps restore more consistent unloading and pressure control.   

Is this an OEM part?

This is an OEM-equivalent replacement blowdown valve designed to meet the same performance standards as the original Sullair valve.

What are the signs that the 02250151-201 blowdown valve needs to be replaced?

Common signs can include air leaking, poor unloading behavior, difficulty relieving pressure, or performance issues tied to pressure regulation and blowdown function. If the existing valve or manifold is worn, sticking, or no longer regulating and venting properly, replacement may be necessary. Because this part is often described as a pressure regulator / blowdown manifold, issues may show up in both unloading and pressure control behavior.

How difficult is it to install?

Blowdown valve replacement is generally considered a mechanical service task involving removal of the old valve or manifold and installation of the replacement in the correct air/oil system location. Because this part is tied to the compressor’s pressurized control and unloading system, installation should always be performed with the machine shut down, isolated, and fully depressurized before service.     

Do you carry other parts for Sullair compressors?

Absolutely. We stock air filters, oil filters, belts, valves, intercoolers, aftercoolers, lubricants, rebuild parts, and more for Sullair compressors. If you don’t see what you need, just ask and we’ll help you find it. 

How do I know which oil to use in my Sullair compressor?

Stationary rotary screw compressors may have specific oil requirements that differ from reciprocating or portable units. To make sure you’re using the right lubricant for your machine, check out our full guide here: Choosing the Right Oil for your Sullair Compressor. It covers the recommended options for rotary screw compressors and helps you match your compressor with the proper oil.
