Apollo Disc-Kleen Filter

Filter more for less - the Apollo Disc-Kleen Filter allows you to filter more for less, saving valuable time and money. It has all the benefits of the Galaxy Filter, but with these enhanced features.

Save money by reducing filter size. The Apollo features a longer filter element (spine) with larger discs (rings) producing a 20% larger filtration area than a comparable Galaxy filter. This large filtration area means each filter can accommodate a higher flow rate which lowers the price per GPM of filtered water. The total number of filter units required for a specific flow rate is reduced lowering the cost of the filter battery.

Save money by reducing pump size and energy costs. Only 30 psi is required for backflushing. This eliminates the need to oversize the pump for adequate flushing and reduces the need for a Pressure Sustaining Normally Open (PSNO) Valve downstream of the filter to maintain adequate backflush pressure.

Save time and money when filter needs moving. The Apollo filter is light-weight with a small footprint making it easy to move. This portability is ideal for crop rotation and rental units in row crop applications.

Save money on maintenance costs over the life of the filter. Made from high density synthetic materials, the Apollo filter is corrosion-proof not just corrosion resistant. Chemical injections upstream of the filter unit will not damage any filter components.

Save time and money with this pre-assembled filter. It arrives fully assembled for a quick and easy water in/water out installation. A small footprint reduces the size and cost of the concrete pad.

Features & Benefits

  • More filter area with longer filter element and larger discs
  • Less pressure required for cleaning – only 30 psi
  • Shorter length of flush cycle - less interruption of water flow to the field while irrigating
  • Portable and easy to move – can be mounted on a small utility trailer and easily moved from field to field
  • Less overall water used for flushing - shorter overall flush cycle ensures better uniformity of irrigation and less flush water to dispose or filter for reuse
  • Lower installation costs – pre-assembled and ready to install
  • Smaller footprint – easier and faster to install while saving money on concrete pad size
  • Eliminates leaks and rusting – synthetic materials are not damaged by chemical injection or organic materials in the water and will no corrode


  • Systems Requiring High Volumes of Water

Apollo Disc-Kleen Filters Operation

Disc filters fall into the category of “depth filtration” filters because they add an additional dimension to the cleaning process. A filter element contains a stack of compressed discs with an overlapping series of grooves that force the debris to move through numerous trap points. This process increases the likelihood of capturing debris. Because of the increase in filtration surface area, the frequency of cleaning drops and cleaning is easier.

The discs are color coded by mesh size and are selected according to water filtration requirements. The spine assembly has a spring compression unit and an internal piston which are used to alternately compress and release the discs during filtering and backflushing cycles.

Filtration Mode

During the filtration process, the discs are tightly compressed together allowing clean water to pass through the discs and trap debris.

Backflush Mode

As debris in a filter increases, the backflush process is initiated. During backflush, the discs separate and jets of clean water spray and spin the discs removing the trapped debris which is then flushed out.

Improved Filter Spine

With a longer spine assembly and larger discs, the Apollo Filter has a 20% larger filtration area than a comparable Galaxy filter. The Apollo features a redesigned piston which allows backflushing at lower pressure, 30 psi – 25% lower than a Galaxy.

Easier Access to the Discs

With an easy-to-release clamp around each filter, there are no tools required to remove the filter cover and access the discs. This makes maintenance and troubleshooting quick and simple.

Water Quality Maximum Flow Rates

Good Water Quality: Municipal water supply or well water from a clean aquifer with no sand, iron or manganese.

Average Water Quality: Wells with small amounts of sand (< 2 ppm) or clean surface water which includes lakes, ponds, reservoirs and canals.

Poor Water Quality: Well water from a poor quality aquifer (> 2 ppm) or surface water in hot climates with increased biological growth and no chemical treatment which includes lakes, ponds, reservoirs and canals.

Very Poor Water Quality: Well water with greater than 10 ppm of sand including rivers, muddy canals, lakes and ponds with severe run off deposits and raw municipal wastewater. Greater than 3 ppm Sand or Silt: May require a pre-filter such as a hydrocyclone.
