Double Length Bag Filter – 20 micron

Description

Polypropylene Replacement Bag Filters for Sediment Filtration

Eaton SENTINEL® bag filters help reduce suspended sediment in water before it reaches downstream treatment equipment. They are used inside a compatible bag filter housing, where the support basket holds the bag in position during operation.

Water passes through the polypropylene needle-felt media, which retains particles according to the selected micron rating and operating conditions. Collected sediment remains inside the bag until it is replaced.

Understanding the Micron Rating

A micron is one-thousandth of a millimeter. A lower micron rating indicates finer particle filtration.

A 1 micron bag filter provides finer sediment filtration than a 5 micron bag. However, finer filtration can cause the bag to load more quickly when the incoming water contains large amounts of suspended material.

The micron rating does not guarantee complete removal of every particle of that size. Performance also depends on the filter media, flow rate, sediment loading and correct installation.

Micron Ratings

The SENTINEL® needle-felt range is manufactured in polypropylene and polyester, with retention ratings of 1, 5, 10, 25, 50, 100 and 200 micron.

Choosing the Correct Bag Size

Size 1 is a single-length bag measuring approximately 180mm in diameter × 430mm in length.

Size 2 is a double-length bag measuring approximately 180mm in diameter × 810mm in length and provides twice the filtration surface area of Size 1.

The sizes are not interchangeable. Confirm the housing model, support-basket dimensions and sealing-ring compatibility before ordering.

What Bag Filtration Removes

Bag filters capture suspended particles such as sand, silt, rust and dirt. They can improve water clarity where cloudiness is caused by particles retained by the filter media.

Treatment Limitations

Sediment filtration does not soften water, remove dissolved salts or reduce total dissolved solids. These bags are not designed to remove dissolved iron or manganese, and they do not provide reliable disinfection.

Water may appear clear after filtration while still containing dissolved contaminants or microorganisms. Additional treatment may be required according to the water quality and intended use.
