Selection And Precautions for High‑Flow Pleated Filter Cartridge Housings

Selection Guidelines

When selecting a High‑Flow Pleated Filter Cartridge Housings, the following key factors need to be taken into consideration:

1. Fluid Properties: Clarify the chemical composition, pH value, temperature and viscosity of the liquid to select appropriate filter cartridge and housing materials.

2. Flow Rate Requirements: Determine the maximum, minimum and average flow rates required by the system, which serves as the basis for selecting the filter model and the number of filter cartridges.

3. Filtration Precision: Confirm the required absolute or nominal filtration precision according to the protection requirements of downstream equipment or the cleanliness standards of the final product.

4. System Operating Conditions: Understand the working pressure and temperature range of the system to ensure the safe and stable operation of the filter and filter elements.

5. Contaminant Load: Estimate the content and properties of suspended solids in the liquid, which directly affects the dirt-holding capacity and service life of cartridge filters and is an important basis for determining the maintenance cycle.

6. Installation Space: Consider the on-site installation conditions and select vertical or horizontal configuration, as well as single-unit or multi-unit parallel configuration.

Precautions

Differential Pressure Monitoring: It is recommended to install inlet and outlet pressure gauges. When the differential pressure reaches the maximum value recommended by the manufacturer (usually 2–3 bar), the filter cartridges should be replaced in a timely manner to avoid filter cartridge damage or insufficient system flow rate.

Proper Installation: When installing element filters, make sure that the O-rings are intact and correctly positioned to prevent liquid short-circuiting and avoid compromising filtration efficiency.

System Air Venting: Before the filter is put into operation, the air inside the housing should be fully exhausted to avoid the "air hammer" effect and impact on the filter cartridges.
