The Cary Company's extended surface pleated polyester liquid filter bag offers an extended service life of about 4x the life of a standard nominal bag under normal operating conditions. With a design for longevity and high dirt holding capacity, this pleat bag filter features two pleated layers of nominal felt to create a pre-filter and final filter inside a standard Size #1 or Size #2 bag. Extended surface pleat bag filters can reduce operation costs as they do not need to be changed as frequently - reducing downtime, cutting labor costs and replacement filter fees.

Extended surface pleat polyester filter bags will fit into most Size #1 or #2 strainer baskets. With micron ratings from 1 micron to 100 micron, these silicone-free bag filters are suitable for a wide range of applications including: quality assurance, product isolation, product standardization and more. The polyester filtration media has good chemical resistance and meets FDA regulations for food contact under CFR21, Section 177.1520. Customizable options include micron rating, industry standard size, ring style including plastic flange or steel ring. Configure the ideal extended pleat polyester liquid filter bag here!

What is the difference between a felt and mesh filter bag?
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.
What are the components of a filter bag part number?
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.
Is a liquid filter cartridge the best industrial filtration product?
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.
What is the difference between a bag filter and a cartridge filter?
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.
What is the difference between a sewn and welded seam?
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.
What are the benefits to the different ring styles?
The Cary Company offers three different ring/flange styles, the steel ring, plastic flange, and a drawstring. The steel ring bags have a galvanized steel ring sewn into the top of the bag. This is sewn directly into the top of the bag. It will contain a cotton handle and is designed to gasket as well as support and secure filter bags when placed into the housing. When steel or stainless steel rings are being used, we recommend calling in and speaking to a filter specialist for more information and verification. Plastic flange bags have a specially designed flange sewn to the top of the bag. The molded plastic with built-in handle makes installation and disposal faster, cleaner, and less expensive. The smooth plastic design prevents build-up of contaminants around the header. It also contains a collar that is sewn or welded into place to ensure that plastic media remains firmly intact.

What does the micron number mean on a filter?
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.
Will a filter work for paint? Dust? Water?
While there are many different uses for the various filter bags The Cary Company offers, please refer to the chemical resistance guide for more information
Where do the filters ship from?
Many of our liquid filter bags ship from our warehouse in Addison, IL. For more information about where our bags are shipped from, please contact us at 630.629.6600
What is the recommended operating temperature for filter bags?
The recommended operating temperature will vary depending on the different materials and media. Please reference the chemical resistance guide for more information.
Where can I go to find out more information about what filter vessel or bag is right for my business?
We have Filtration Specialists available to answer questions and suggest filter vessels, bags and more. They can go over more information if you complete our Filter Housing Worksheet.
My product includes chemicals. How do I know which filter bag or cartridge works for my chemical?
