Durable, Long-Lasting Construction- Everfilt’s stainless steel media filters are constructed using heavy 11 gauge 304 stainless steel. Unlike some other media filtration systems, users will never see an Everfilt tank flex during start-up or backwash because thin gauge stainless steel has been used in the filter’s construction.
Everfilt’s heavy gauge stainless steel assures long lasting trouble-free operation. For maximum strength, Everfilt has chosen a rounded dome shape for its tank top and bottom so that filter operation will be effective even at higher psi’s or pressure differentials.

Everfilt also manufactures stainless steel media filters which are constructed using heavy 11 gauge 304 stainless steel. Learn how media filters operate during media filtration and water filtration operations.
All-Stainless, All-Welded Underdrain – Everfilt pioneered the design of the radial hub stainless steel underdrain – and many other manufacturers have since followed our lead.

Everfilt’s underdrain is hydraulically balanced to assure efficient collection of filtered water. The lateral collection screens are matched to the natural flow of water through the filter. It also means that during backwash, the filter bed is lifted uniformly and fully, thus achieving complete cleaning and regeneration of the media.
The high strength profile wire screen retains medias finer than No. 20 silica sand, thus eliminating the need for filter back-up screens. The non-clogging characteristic of the screen makes it the most reliable collection system available.
Everfilt is also the only manufacturer whose underdrain is all stainless steel construction and fully welded. The added strength results in years of trouble-free, reliable operation.
Heavy-Duty Backwash Valve – Everfilt’s backwash valve body is made of high strength 3M-134 industrial grade epoxy coated ductile iron – a material known for its resistance to corrosion. All wetted surfaces are stainless steel or epoxy coated. The hydraulic design prevents valve slamming and eliminates possible damage to the valve and manifolding.
Backwash valves can be ordered for manual, semi-automatic, or automatic operation.
Automatic Backwash Control – Everfilt designs and manufactures its own automatic backwash controls. User friendly control knobs, panel labeling and display lights make for easy use. Made of solid-state electronic circuits, the automatic controls help assure effective system operation by initiating needed backwash in an efficient manner. The control can be set to trigger backwash either when a specified pressure differential or time interval is reached. The control is housed in a water resistant enclosure.
An optional LCD readout indicates when the next backwash cycle is timed to begin, the total number of backwash cycles that have been initiated since last reset, and the number of backwashes that have been triggered by pressure differential. Users find this information very useful in identifying operating conditions requiring their attention.
Models are available for 4, 8, 12 station controls. Thus, in some cases it’s possible to expand an existing filter installation without the expense of changing controls.
Deep Bed Filtration – For applications where slow, deep sand filtration is required to achieve low micron filtration, a high jacket tank is available. Consult the factory for specific sizing.
Solar Power – For field conditions where electric power is unavailable or unreliable, or where it is just more cost-effective, Everfilt offers a 12-volt DC solar power option. The heavy-duty battery has the capacity to deliver power to the system even in overcast weather.
