liquid filter bags

Liquid filter bags are used in various industries to remove impurities and contaminants from liquids. They are made of different materials such as polyester, polypropylene, nylon, and felt, depending on the specific application and desired filtration efficiency. Here are some important details about liquid filter bags:

Filtration Efficiency: Liquid filter bags are available in different filtration ratings, typically ranging from 1 to 2000 microns. The filtration efficiency determines the size of particles that can be effectively removed by the bag.

Bag Size: Liquid filter bags come in various sizes to fit different filter housings. The most common sizes are #1 (7″ diameter x 16″ length) and #2 (7″ diameter x 32″ length), but other sizes are also available.

Bag Construction: Liquid filter bags are typically constructed with a sewn or welded seam to ensure durability and prevent bypass of contaminants. The construction method may vary depending on the material and intended application.

Collar Type: Filter bags can have different collar types to fit different filter housings. The most common collar types are snap ring, flange, and drawstring. The collar provides a secure attachment to the filter housing.

Bag Material: The choice of bag material depends on the compatibility with the liquid being filtered. Polyester and polypropylene bags are commonly used for general-purpose applications, while nylon bags are suitable for higher temperature and chemical resistance requirements. Felt bags are often used for applications requiring high dirt-holding capacity.

Bag Configuration: Liquid filter bags can have different configurations, such as single-layer, multi-layer, or pleated. Pleated bags offer increased surface area and higher dirt-holding capacity, while multi-layer bags provide improved particle retention.Bag Support: Some liquid filter bags come with an internal support basket or cage to provide structural integrity and prevent bag collapse during operation. The support structure helps to maintain consistent filtration performance.

Bag Cleaning and Disposal: Liquid filter bags can be cleaned and reused in some applications, depending on the level of contamination and the bag material. However, in most cases, filter bags are disposable and need to be replaced when they reach their maximum dirt-holding capacity.

It is essential to consider the specific requirements of the application, including flow rate, pressure, temperature, and chemical compatibility, when selecting the appropriate liquid filter bag.
