Fernox Total Filter TF1
“The Fernox Total Filter TF1 is a revolutionary in-line filter, which combines hydrocyclonic action with specially designed magnet assemblies, to remove both magnetic and non-magnetic contaminants from system water and contain safely within the filter.” –www.fernox.us
This hydronic system filter provides exactly what the manufacturer reports, all built in to a robust assembly. Its a hydrocyclonic filter and provides debris/sludge seperation via a vortex action. The overall design of the filter allows for multi-position installation. As you can see in the photos below I chose to install it in the vertical position, which is how you will find it ready to go right out of the box. Instructions and different O-ring seals are included in the packaging if your installation requires the filter to be piped horizontally. The filter is designed for use in combination with Fernox ‘F’ range water treatment products.
The glass fiber reinforced Nylon plastic housing is rated for operating temperatures up to 257°F, well above any hot water boiler system temperatures. The plastic housing has a removable screw top lid, built in to it are a vent/chemical dosing fitting along with a sturdy magnetic rod. The magnetic rod inserts through the lid and attracts magnetic particles, such as iron oxides and rust, to the inside of the canister housing. Simply close the flow through the [provided] 1” copper sweat ¼-turn ball valves; pull the magnet out and all the collected debris will drop to the bottom where it can be flushed out of the canister via the built-in ¼-turn hose thread drain valve.
When installing this filter on the return line of a closed hydronic system you gain the ability to protect system components such as flow restrictive boiler heat exchangers, small diameter tubing, zone valves, air elimination devices and much more. The relatively low cost and minimal maintenance required is well worth the benefits provided, especially when comparing the initial cost verses system component repair/replacement due to clogging/corrosion.
