Self-Cleaning Filters / Cone Filters

Cone Filters are used to catch and filter any type of debris from the waste stream. A variety of mesh screens are available to remove small micron sized particulate as well as larger 1/4 inch sized particles. The cone filter has been highly successful in a great number of applications such as pumping from wells and sump pumps that contain solids of any type.

Cone Filters
Cone Filter Technology contains a stainless steel screen filter that is designed for the removal of sand and sediment from well water for the irrigation and liquid fertilizer industry. Our unique filter has grown popular due to its low maintenance design, stainless steel construction, space saving profile, and exceptionally low pressure loss.


All models of the Cone Filter series will operate with less than a 1-PSI pressure loss at maximum flow when clean. This efficiency provides real energy savings when compared to filter products that rely on energy consuming devices like spinners and torpedoes to give a comparable cleaning action. Call us today for a free energy savings estimation.

Choosing a filter with sufficient surface area is critical in any application. The Cone Filter series has significantly more surface area than most traditional basket and y-strainers. Ecologix has a filter that will fit your specific needs with units available from 2" to 10" and flow rates up to 2,000 GPM (higher flow rates are achieved by manifolding multiple filters). Our screen mesh options are available from 16 to 250 mesh.

The Cone Filter's internal flow patterns are responsible for making our unique product so effective. As water flows up through the filter housing and deflects off the surface of the conical shaped filter screen, sediment is effectively forced back down, away from the screen, into the large debris reservoir. The sediment is then easily removed through the flush port. Effective separation of the water and the sediment is achieved while minimizing debris contact with the screen.

The Filter/Strainer vessel is purged while online and in operation. By opening a valve on the flush port, all debris in the lower reservoir is purged from the vessel, as shown. Backflushing or taking the unit off-line is not required to perform this flushing procedure

Pressure Differential Alarm Package (PDA)
To enhance our Cone Filter line of unique strainers; Ecologix has an Instrumentation Package that will monitor your differential pressure and will automatically backflush your strainer over a period of time.

The Pressure Differential Alarm Package (PDA) continously monitors the inlet and outlet system pressure. When the filter screen becomes dirty, a switch-gauge triggers an aubible siren and visual flashing alarm. These alarms are intended to alert maintenance personnel that the strainer screen needs to be removed from the strainer housing for manual cleaning.

The Automatic Timer Flush Package (ATF-EA-1.5) insures that the particulate that falls down to the debris reservoir is automatically flushed. The power supply and timer controls for the valve package are housed inside the watertight control box, attached to the valve. Depending on the application, the end-user simply dials in the flush frequency and flush duration of the valve. Based on the parameters that are programmed, the ball valve quickly opens and closes, minimizing the volume of water that is flushed from the strainer. The valve also comes with a manual flush control switch that can be used to conveniently manually flush the strainer or drain the strainer before removing the screen.
