Automatic Filters

Product catalog summary
Overview: The document provides technical specifications and features of automatic filters, specifically Cepex ring filters, which are designed for modular configurations and can be automated using 12V or 220 VAC. These filters are suitable for both low and high-pressure installations, including brackish and sea water, with options for backwashing supported by compressed air.
Specifications: The filters are available in various configurations, with connections ranging from 2” to 4” and multiple filters in line. The maximum flow per filter varies from 20 m3/h to 63 m3/h, with a minimum backflushing pressure of 2.8 bar and a maximum temperature/pressure of 60ºC/140 F and 10 bar/145 psi.
Features: The filters execute the backwash process while continuing filtration, allowing for continuous operation. They are compact, made from plastic to prevent corrosion, and require minimal maintenance. The system is designed to save water and energy through its automatic backwash and TWISTER system.
Modularity and Installation: The system allows for a wide range of configurations with a minimal number of components. It includes high-density polyethylene collectors for easy installation, high resistance, and durability. The filters are self-cleaning and can handle disks with valves of 2”, 3”, or 4”.
Operation: Filtration occurs as water enters the filter, creating a centrifugal movement that pushes dirt against the filter walls. During backwash, clean water enters in the opposite direction, decompressing the discs and expelling dirt through the drainage output. The transition between phases is managed by the hydraulic filter valve.
Performance Data: The document includes detailed tables showing the relationship between the number of filters, maximum flow, backflushing pressure, and filtering surface area. It also provides pressure loss data for various configurations.

Automatic Filters Filtration: when the water enters the filter through the helix, it starts a centrifugal movement that pushes the dirty particles against the filter wall Cleaning: the backwash is produced when the clean water comes in through the coil filters in the opposite direction to filtration, the discs decompress and the water pushes the dirt towards the outside. The solids are expelled through the drainage output. During the backwash the flow is provided by the filters that are not being cleaned. The change from one phase to another occurs through the simultaneous change in position...
