Alfa Water has created a patented upgrade for Filtrex water filtration systems.
Unlike traditional heavy multi-layer cartridges, the Alfa Water solution uses an optimised three-layer structure designed to maximise the available filtration area and simplify maintenance.
After the modification kit has been installed, you only need to replace the filter fabric every ~5 years, which fits in an envelope and no special tools are required for replacing this filter.
First installation took place in 2022 and 400 Filtrex modification kits have been installed since on more than 200 vessels.
KIT CONTENT:
This Alfa Water retrofit kit replaces the internal cartridge and cleaning system with an upgraded filter technology, while retaining the existing filter body and cover. After the upgrade you will enjoy:
- Lightweight cartridge construction
- Greater free filtering area
- Lower pressure drop
- Higher flow capacity
- Highly abrasion-resistant 3D filter fabric
- Consistent filtration efficience over time
The Alfa Water selfcleaning mechanism restores the filter every cycle:
- No gap between suction shoe and filter medium
- Complete suction over the filtration surface area
- Effective contaminant removal
- No permanent deposits
- Reduced progressive clogging
