Both felt and mesh bags will meet FDA regulations, however felt bag materials have a high dirt holding capacity, temperature ranges up to 500° F, the ability to remove both solid and gelatinous particles, and the singed/ glaze finish on polyester and polypropylene reduces fiber shredding. Mesh bags on the other hand contain a silicone-free construction, have a high flow/low pressure media, a wide chemical compatibility, and the temperature ratings to 350° F.

There are many different components that go into creating a filter bag part number. These components include the media type, the micron rating, the bag dimensions, the ring/flange style, and also different customizable options. For more detailed information, take a look at our Guide to Liquid Filter Bags.

When it comes to physical sediment filtration, some of the most common industrial filtration products are cartridge filters and liquid filter bags. Both have the ability to remove solid or gelatinous contaminants during liquid filtration in a variety of applications including industrial waters systems, chemical processing equipment, etc.

A cartridge has many advantages. For example, it has the ability to compact, it has a lower initial investment, it is more suitable for fine powders with lower concentrations and is recommended for sandblasting lines. These are not recommended for very fine powders. A bag filter, on the other hand, is more flexible, is more suitable for powders of various nature and sizes, is easier to clean with the assistance of an automatic system and has a lower energy cost.

A sewn seam is the industry standard. It uses a 5-line system when sewing and has a strong construction for that heavy dirt holding capacity. A welded seam is available in polypropylene and polyester felt for #1, #2, #3, #4, and #5 plastic flanges. There are no needle holes or thread contamination. It contains a precision bonded cutting of the fabric edges and maintains the same efficiency as filter media.

The Cary Company offers three ring and flange styles: steel ring, plastic flange, and drawstring. Steel ring bags feature a galvanized steel ring sewn directly into the top, along with a cotton handle, providing a secure gasket and strong support within the housing. When using steel or stainless steel rings, we recommend contacting a filter specialist for more information and verification. Plastic flange bags include a molded flange with a built‑in handle for faster, cleaner installation and disposal. The smooth design reduces contaminant build‑up, and the sewn or welded collar keeps the media firmly in place. Drawstring bags offer an adjustable top diameter for easy tie‑on piping, making them ideal for gravity‑feed applications and simple disposal.

The micron rating is the size at which particles are retained by the filter. For example, a five-micron filter will stop particles of 5 microns or larger from passing through the media. A micron is a micrometer which is a thousandth of a millimeter.
