EM Series – Horizontal Self-cleaning Filter

EM Series - Horizontal Self cleaning Filter

The EM Series filters feature a unique automatic self-cleaning water filter configuration. EM series filters are often referred to as horizontal self-cleaning filters and can be installed in any orientation.

The EM Series Self-Cleaning Water Filter has a parallel flange configuration for easy installation. Can be integrated with any straight tube.

The EM series of industrial water filters are characterized by a two-stage screening. Each water filtration system consists of a coarse screen and a fine screen. The coarse screen is responsible for filtering out large debris from the water source, and the fine screen purifies the water to the specified requirements.

These automatic water filters provide solutions for a variety of industrial, irrigation and municipal applications.

Screen Options

                                           Sintered Mesh on Perforated Metal Plate

  • Degree of Filtration Options (Micron): 5, 10, 25, 50, 75, 100, 120, 150, 200, 300, 500, 1000, 2000.
  • Material: Standard 316L stainless. Screen is fused to stainless steel perforated plate for maximum durability.
  • Particle Removal: 98-100% particle removal efficiency above the degree of filtration
  • Flow Capacity: Maximize flow per square inch of screen area with sintered mesh

                                                                 Wedge Wire

  • Degree of Filtration Options (Micron): 25, 50, 75, 100, 120, 150, 200, 300, 500, 1000, 2000.
  • Material: Standard 316L stainless.
  • Particle Removal: 98-100% particle removal efficiency above the degree of filtration. Great for removal of fibrous material including pulp and paper fibers, fibrous algae, fruit fiber in juice processing, etc.
  • Bursting Pressure: Robust construction ideal for high pressure environments

How to Size and Select Self Cleaning Water Filter

STEP#1- Determine Desired Micron Filtration Level

  • 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.
