POLO filter Germany POLO model POLO price

The POLO filter is the first coarse filtration device for whole-house water usage, capable of filtering large particles such as sediment, rust, insect eggs, and midge larvae from tap water. Pre-filters are generally installed at the front end of pipelines, hence the name "pre-filter"; "filtration" refers to the basic principle of this type of equipment. A filter (filter) is an indispensable device on media transport pipelines, typically installed at the inlet of pressure reducing valves, relief valves, constant level valves, and other equipment. The filter consists of a housing, a stainless steel filter screen, a sewage discharge section, a transmission device, and an electrical control section. Applications include industrial wastewater, circulating water filtration, emulsion regeneration, waste oil filtration treatment, continuous casting water systems in the metallurgical industry, blast furnace water systems, and high-pressure water descaling systems for hot rolling. It is an advanced, efficient, and easy-to-operate fully automatic filtration device.

POLO Filter Introduction

It typically features a "T" type structure. The horizontal bar represents the water inlet and outlet at the left and right ends, respectively. The vertical bar represents the body and the internal cylindrical filter screen, with the sewage outlet at the bottom, controlled by a valve for opening and closing. The filter screen precision ranges from 5-300 microns depending on the brand and model. It mainly removes precipitated impurities generated by pipelines, as well as bacteria, microbial residues, rust, sand, and mud, and other particulate impurities larger than 9 microns. It is usually installed after the water meter on the inlet pipeline to ensure that large amounts of precipitated impurities generated in the network do not harm the human body, and to provide positive protection for concealed pipelines, faucets, and electrical appliances. The filter is the nemesis of secondary pollution and is a reliable impurity filtration device.

POLO Filter Working Principle

When flushing retained matter is required, the flow direction is reversed manually or automatically by adjusting the multi-port diverter valve integrated into the filter, causing the raw water to flow from the clean water side of the filter screen (core) to the raw water side, achieving backwashing. Common backwashing pre-filters typically operate in an "internal pressure" mode (as this structure facilitates multi-port valve design), where tap water pressure permeates from the inner wall to the outer wall of the filter screen (core). Particulate impurities such as sediment and rust are retained inside the tube. Opening the flush valve washes away the impurities trapped by the filter screen. If the water quality is poor and the user does not flush for a long time, clogged filter pores are not a concern. Through the backwashing function, an "external pressure" mode is formed, washing away impurities embedded in the filter mesh pores that could not be removed by forward flushing. Compared to previous products, backwashing pre-filters represent a significant technological improvement. The flushing design is reasonable, allowing flexible forward and reverse flushing to thoroughly remove impurities and eliminate secondary pollution caused by impurity accumulation.

Wide Application of POLO Filters

Fine particles can cause pressure reducing valves to fail within a short time (leading to dripping in disc-type ceramic valve cores), blockage and rupture of heat exchanger pipelines, and impurities will precipitate on the pipelines. This provides a breeding ground for bacteria and forms electrochemical compounds. It can filter visible impurities such as sediment, rust, and floating matter, significantly extending the service life of downstream equipment. In Germany, legislation mandates that all buildings constructed after 1992 must install pre-filters. They are widely used in general water supply filtration systems for the food, textile, mining, electronics, and casting industries. Nozzle water filtration for the pulp and paper, metallurgical, and mechanical industries. General circulating water filtration for the food, power, mining, and smelting industries. Filtration of cooling tower circulating water for pharmaceutical, petrochemical refining, air conditioning, or heating systems. Pretreatment for sewage ion exchange in petrochemical, electromechanical, and pharmaceutical industries.
