Description

amaFlow multi-layer needle felt filter bag

AP – XL/z – x/z – x/y/z

SP – XL/z – x/z – x/y/z

The amaFlow multi-layered needle felt filter bags have improved filtration properties and extended service life due to their increased depth design. The dual or triple layer filter design can be optimized to suit specific applications, resulting in improved filtration efficiency.

Features

  • Filter bags with multiple layers can be useful for removing particles which are usually difficult to filter.
  • Multi-layer also gives a longer filter life.
  • The contaminants are gradually removed from the liquid when filtered through the graduated layers of filtration media.
  • These bags can be made from material with the same or different micron ratings.
  • Bags are quick and easy to change-out.
  • Inside-out flow keeps contaminants enclosed in the bag.
  • The standard filter bags are sized to fit into our baskets and housings, but will also fit into most other housings.
  • Special sizes are available on request.
  • Available as an option are antimigration covers on the felt, made either from non-woven nylon fleece or very fine nylon mesh.
  • Bags are silicone-free (does not apply to 0.5 μm AP bag) and are produced in a silicone-free environment.
  • Materials used for amaFlow AP and SP comply with the European Regulation EC1935/2004 and EU10/2011 (Materials that come in contact with food).

Typical applications

  • Food and Beverages
  • General chemical

Types

The amaFlow extended life (XL) bags are double-layer bags with a 200 μm needled felt as the first layer. This first layer removes the larger particles, thus reduces the contaminant load to the final layer, increasing the service life of the filter bag.

Sealing system

In order for bag filters to function properly, especially with smaller pore sizes, a good seal between bag and support basket is of great importance. For this reason, there are two options:

  • The Snap-Collar; a felt-covered metal or plastic ring which clicks neatly into the upper collar of the support basket. The felt serves as the sealing.
  • The plastic flange (with handles) which tightly fits into our standard baskets. Available in polypropylene and polyester.

Surface treatment amaFlow multi-layer needle felt filter bag AP – XL/z – x/z – x/y/z SP – XL/z – x/z – x/y/z

Polypropylene and polyester are thermally treated on the outside as standard. This will further minimize any possible release of fibers from the needled felt filter media. During the thermal treating process, the softened fibers are bonded together on the downstream side of the bag.

The filter bag must be properly mounted into the support basket before starting the filtration process.

Brand

amafilter

In the 1930’s Mr. L. Benjamins started a company in the Netherlands which sold filtration consumables and parts. After WW2 Mr. L. Benjamins and his son started importing and not much later the manufacturing of “Niagara filters” branded as “Amsterdamse Machine- en Apparatenfabriek” (amafilter®). The main products were vertical pressure blades for the food & beverage industry. Soon after amafilter started exporting it’s products worldwide. Due to rapid growth amafilter® moved from Amsterdam to Alkmaar. The new location in Alkmaar expanded multiple times to offer more production capacity. In those years many filter types were developed. Many filters were added to the amafilter scope of products. The amafilter® brand is a well established name in the global market for solid-liquid filtration serving customers worldwide.

LFC Lochem

In 1979, three employees of Machine Factory Arnhem in the Netherlands started their own company to manufacture pressure leaf filters and named the company “Liquid Filtration Consultants“ or “LFC Lochem®”. The company quickly gained an outstanding reputation as an innovative engineering and manufacturing company that specialized in liquid filtration technology. Over the years, LFC Lochem® developed and perfected many filtration products. This resulted in a high quality, comprehensive standard range for widely diverging industries. LFC Lochem® has an excellent reputation in the field of filtration technology and on its ability to quickly respond to specific customer requests.
