How To Identify Your Blower Model

1. Blower Identification Plate

When your blower originally shipped from the manufacturer it would have an identification plate with information about the unit.  Name plates may include some of the following details:

  • Model – This indicates the unit model and the configuration at the time of shipping. Many units are configurable and may no longer have the same configuration specified here.
  • Part – This number is very helpful for gathering additional information from the manufacturer if needed.
  • Serial – This number is unique to your blower and may include coding that indicates a date of manufacture. This number is needed for warranty claims.

Information found on the identification plate is the best way to identify your unit.  If you have questions about your blower or need repair services or parts, please send this information or a picture of your plate.  You can attach the photo to our contact form.

2. Visual Identification

If you have a Roots™ blower, head over to the blower catalog on our website and browse through the different models to find the one that looks like your blower.

Keep in mind that many of the blowers can be reconfigured into multiple drive shaft and flow orientations; click here to see the different configuration options. If you find a potential match, look at the model specifications to see if it matches your unit.

3. Take Measurements

If you haven’t been able to identify your blower, the team at pdblowers can help. There are several measurements that will help us identify which model you have:

  • Measure the shaft diameter and distance between shaft centers
  • Measure the connection size
  • Is the connection threaded or flanged?
  • What is the connection orientation?
  • Are the feet detachable or cast into the headplate?

Send us this information through our contact form, as well as photos of your ID plate and blower if possible, and our team will be happy to assist you.
