High-Temperature Filter Bags
High-temperature filter bags are manufactured to be heat-resistant, with linings that resist heat damage. They ideally perform in applications where hot liquids are involved, like cooking oils or chemical processes that generate heat.
Micron Rated Filter Bags
Micron rated filter bags are grouped on the basis of their micron ratings that show the size of particles they can filter. For example, a 5 micron filter bag would collect particles above the size of 5 microns. The ratings provide users with the right choice of a bag when using it for proper filtration purposes, hence ensuring all contaminants are removed.
Custom Filter Bags
Specially designed filter bags can cater for unusual filtration needs in an industry. Manufacturers can provide filter bag specifications with specific micron ratings, size specifications, or special materials to cater for the demands of most applications. This ensures maximum working performance in diverse environments.
How to Choose the Right Liquid Filter Bag
The following would be considered when selecting a liquid filter bag:
- Type of Liquid Being Filtered: Determine the viscosity and chemical composition so that the material and type of bag applied can be appropriately chosen.
- Desired Micron Rating: select a specific micron rating to the size of particles needed to filter. This is somewhat of a choice to be made to influence the activity of filtration.
- Requirements for Volume and Flow Rate: Determine the volume of liquid you need to filter and the flow rate, then see that the selected bag is capable enough to support your requirements.
- Compatibility with Filtration Systems: Fit the bag filter onto your filtration system, including the filter housings and the connection points, such as a plastic flange or steel ring.
Tips for Assessing Your Needs
