CARTRIDGE FILTER & BAG FILTER
Both bag and cartridge style filters offer you removable media and collection of a discrete phase of matter existing in a dispersed or colloidal state in suspension. The decision should be based on the application because each type of media has its advantages and disadvantages.
CARTRIDGE FILTER
Cartridge filters capture solid contaminants on the outer surfaces of the filter media.
These cartridge filters can be used for a wide range of applications where sub-micron filtration is needed. These include pharmaceutical applications as well as those in which ultra-pure water filtration is required: beverage and food production facilities, chemical and paint plants, as pre-treatment for reverse osmosis system / ultrafiltration system / water purification technologies.
Cartridge filters materials in Polypropylene, Polyethylene and PVDF depending on application, temperature, medium etc. All lengths are available in executions of 1 till 120 filter cartridges.
Special customer wishes can be taken into account. The filter housings are available for all possible filter adaptors as DOE, C2, C3, C7 and C8.
ADVANTAGES
- Different kind of plastics for practical all applications
- Position of inlet and/or outlet can be changed
- Standard operating pressure 6 and 10 bar
- In accordance with the PED standards
- Can be CE marked

BAG FILTER
Bag filters are often the best choice for many industrial applications. Bag filters use a wide range of filtration media based on the application such as activated carbon, needle felt, and nylon monofilament mesh.
Bag filters operate by trapping waste solids inside the bag and are considered to be a relatively low-cost form of industrial filtration. However, bag filters have a smaller surface area than most cartridge filters. The low overall operating cost makes bag filters an excellent choice for small batch operations where the cost of a self-cleaning system would not be justified.
Along with this, small operations will not have a high bag replacement frequency leading to lower disposal costs.
Bag filtration systems tend to produce less solid waste than cartridge filters, making them an excellent choice for applications where the user wants to minimize their volume of waste.
ADVANTAGES
- The filter housings are suitable for all standard available filter bags
- Different kind of plastics for practical all applications
- Position of inlet and/or outlet can be changed
- Standard operating pressure 6 and 10 bar
- In accordance with the PED standards
- Can be CE marked
The standard sizes 1, 2, 3 and 4 or a customer specified size can be combined to multiple units. Optional are multi bag housings. The maximum available size is 14 filter bags size 2 in one housing. Special customer wishes can be taken into account. The large choice in filter bags as to material and filter rating makes this a cheap solution for many applications. Strainers are available in various executions and capacities suitable as pre-filtration for cooling water with removable basket for easy cleaning perforation (starting with 3 mm).
