Anyone who has had to order or search for an Eaton filter bag by model knows their part naming system can be a bit confusing. Here, we'll break down the part number structure in attempts to demystify the Eaton filter bag ordering experience.

One of the most helpful resources for Eaton filter bags is their "Bag Nomenclature Chart". this displays many of the bag options and gives you an idea of just how many combinations can be made (there are thousands). Follow along with the chart, here.

A full Eaton bag filter part number will have 8 different identifiers. Note, this could be made up of 10 to 19 digits. For the most part, a dash separates the identifiers. Each of these eight pieces of the part number tells something about the filter bag order. In order, these are the bag material, the micron rating, cover type, bag size, ring type, special options, bags per box, and box size. Whew!

Anyone familiar with PVC pipe understands why it’s used in so many applications worldwide. PVC is a thermoplastic that is surprisingly strong and rigid. This material is especially perfect for piping systems as it does not rust or corrode, and it can stand up to a number of common chemicals.

If you are REALLY familiar with PVC, you probably also know that it now comes in clear form. These clear PVC pipes and fittings are harder to come by than standard white or gray PVC. Where you do find it, clear PVC is often more expensive than standard PVC of the same size and schedule.

Why? For one, clear PVC is scarcer than white or gray pipe. It also must be carefully manufactured, monitored, and packed in order to maintain the highest clarity possible. Extra care must be taken to keep it scratch-free, as the aesthetics are really the selling point. Some high end clear PVC is also manufactured to FDA approved standards.

That leads us to the next question… what is clear PVC used for? You can find clear PVC pipe systems used mostly in applications that require visual monitoring or absolute cleanliness. The clear pipe allows user in laboratories, food processing plants, and other processing applications to closely monitor what is happening inside the pipeline. Outside of the institutional and industrial uses, clear PVC is also becoming popular for use in special projects by consumers. These may include everything from fish tank setups to invention prototypes.

Are Eaton and Hayward Strainers the Same?

In 2005, Eaton Corporation, a large diversified industrial manufacturer bought out Hayward Industries, Inc.’s industrial filtration business. For years Hayward had been making a name for itself in the industrial filtration market with strainers and other filtration products.

This was on top of Hayward’s successful swimming pool equipment business. For Eaton, this acquisition was the perfect fit to expand its fluid power systems division, adding around $100 million in yearly sales to its mix.

Today, strainer models that were formerly Hayward are now under the Eaton brand name. This has caused some confusion for Hayward strainer owners looking for replacement parts or units. As time has gone on model names have also changed, making older units even harder to find parts for. Because of these changes you may find some older models still referred to as Hayward and newer models referred to as Eaton.
