prime-phin is a stainless steel bag filter housing specifically designed for the protection of closed-circuit systems from circulating impurities.

Impurities are retained by a wide filtering bag, which reduces the frequency of required cleaning operations. The lid can be quickly opened thanks to the Quick Bolt system with eye-bolts, making the bag easier to change.

Each bag filter housing is designed to accommodate Neodymium magnetic rods ideal for removing ferrous particles such as magnetite. The magnetic rods are not in direct contact with the water, therefore by removing them the particles will fall off into the bag. This feature makes them extremely easy to clean.

The valve installed on the top cover can be used to add chemicals for system cleaning.
