Pentair Star D.E. Filter

Greatest water clarity with least possible attention.

Diatomaceous earth (D.E.) removes particles that are so small they are individually undetected by the human eye, but combine to decrease water clarity. Pentair Star D.E. Filters remove these microscopic contaminants so your water achieves the glass-like clarity only D.E. can deliver.

Plus, Star filters help maintain themselves. An exclusive pre-cleaning feature enables the filter to dislodge trapped dirt and D.E. particles from the filter. A few turns of a knob is all it takes to regenerate the media inside the filter so it is able to provide extended service before periodic cleaning is required.

Other key features include:

• Refined hydraulic design minimizes flow restrictions so the least amount of pumping power produces the optimum flow rates - for lower utility costs.
• All system components manufactured from the most durable and maintenance-free engineered materials for years of service.
• Time-proven vertical media grids with 2-inch spacing provide the most efficient use of D.E. per cycle - trapping more dirt for cleaner water and longer cycle times between cleanings.
• Exclusive, rotatable grid assembly lifts out easily for any required service.

Crystal water clarity has never been easier.

Keeping your Star D.E. filter running right takes little time and couldn't be simpler, thanks to a number of user-friendly features.

• Premium stainless steel clamp permits quick and easy access to internal components.
• Easy to remove, oversized drain plug allows rapid draining
  when cleaning.
• Unique check valve is built into filter inlet port to prevent backflow of D.E. powder into pump - a life-extending improvement over competing filters.
• One-year limited warranty.
