ET Series-self cleaning water filter
The ET series filter unit features high flow filtration with a maximum flow rate of up to 9300 m3/h for high water flow. The inlet and outlet locations are designed on the side for easy installation.
Raw water enters the interior of the screen from the inlet of the filter and then flows through the screen to the outlet of the filter.
The ET Series filter is a vertical self-cleaning filter for harsh environments. With a parallel flange configuration for easy installation and integration with any straight tube.
The ET series industrial water filter is characterized in that the system continuously flows during the self-cleaning process of the entire filter, and the differential pressure switch also continuously monitors the pressure difference inside and outside the filter.
These automatic water filters provide solutions for a variety of industrial, irrigation and municipal applications.

How to Size and Select Self Cleaning Water Filter
STEP#1- Determine Desired Micron Filtration Level
Guidelines:
- City Water > 5 micron
- Ground/Well Water > 25 micronSeawater >40 micron
- Cooling Tower Process water> 50 micron
- Lake/Pond Water > 75 micron
- River/Produced/Waste Water > 150 micron
- Typically you will use 1/3 of the micron rating of the downstream equipment
STEP#3- Identify Desired Filter Configuration
- Screen options wedge net/porous metal sheet sintering Net
- Working pressure 10 bar / 16 bar / 25 bar
- Heavy-duty models offer higher flows
STEP#2-Determine Contamination Level of Current Water Source (ppm)
- Clean: 0 to 25 PPM
- Moderate: 26 to 70 PPM
- Dirty: 71 to 100 PPM
STEP#4-Select Filter Model From Table
- Identify model with equal or higher amount of square inches of screen
- Verify that model selected has a maximum flow higher than required total flow

Install notice
- One check valve must be installed at filter outlet. Return pressure and back water is forbidden, in case of screen out of shape.
- If system wok pressure over 0.8MPa, should install break valve at drain pipe to reduce impact to screen.
- Notice motor rotating direction. Shut off power immediately once back rotating (anti-clock wise ).
- occurs. )
- Installation each part according to arrow direction.
- Sudden pressure relief at outlet pipe is forbidden. Take normal work pressure 1.3MPa for example, if suddenly open branch valve at outlet, it will occur instant huge different pressure, which damage screen.
- Make sure filter used under correct work pressure, capacity.
- If alarms, open by-passvalve for temporary back washing solutions.
- Make sure control box have constant power supplv. If power off, users can open by-pass valve, close in and outlet valve and control box switch.
