What Is A Spin-Down Filter? 

The spin-down filter’s main function is to capture relatively large sediments in the water streams, such as sand, rust, or grit from any source. It can handle large flow rates as well as purify extremely unclean water. This type of filter is designed to trap large blocks of sand, dirt, and debris, unlike a micron-sized sediment filter.

Thanks to the distinctive tornado effect (or spin-down action),  spin-down filters can easily collect a huge amount of sand and debris in the water, making them stand out among other micron sediment filters.

According to experts, spin-down filters are not only highly effective but also economically sustainable. It can significantly reduce the maintenance costs of domestic appliances, including ROs, washing machines, heating systems, and cooling.

The Rusco Spin-Down Filter uses centrifugal force to extract sediment from water. Its screen is enclosed in a clear cover by the Spin-Down filter, with its head designed to divert water into the chamber by circulating water through the filter housing. 

During the process, water and sediment swirl at high speeds around the inside of the cover. Heavy pollutants spin out to the cover’s wall and drop out of the water flow. 

Then, water passes past the screen and out the filter body’s outlet. Any light-weight particles in the water will not pass through this screen. It also explains why users need to open the valve regularly to let all of the dirt and debris out of the housing.

Specifically, the bottom valve is used for easier manual discharge of sediments. While operating, the sediment collection can be seen clearly through the glass housing.
