The two-chamber system allows uniform filtration over multiple water collectors. Cleaning the sand at the top and bottom pushes out the contaminants.
 
- High filtration volume and low pressure loss
- The system has a built-in microprocessor controller that allows operation without human intervention
- Residual impurities can be automatically flushed, and the modules can be alternated while the remaining filters continue with the purification process
- Depending on the quality of the water, quartz sand or garnet can be used to perform a filter action. The minimum diameter should be up to 0.16mm
- The access port allows easy and convenient monitoring of the internal part during operation
