Star

Thermoplastic Regenerative D.E. Filter

By Pentair Pool Products

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. 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” 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.

feature enables the filter to dislodge trapped

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. See warranty for details.

When diatomaceous earth (D.E.) is introduced into the filter system, it coats the filter cloth. As water passes over the filter grids, the D.E. particles capture even the smallest suspended dirt particles. When cleaning is needed, the water flow is simply reversed and contaminants are backwashed away.
