The Pentair 147411 SMBW 4060 SMBW 4000 Series 58 sq ft D.E. Pool Filter provides the highest level of filtration. The 4060 SMBW is capable of filtering out particulate as small as 5 microns. That's the same size as a human red blood cell.

The 147411 SMBW 4060 uses a set or grids coated in pool grade diatomaceous earth. The set of grids consists of 8 full grids 30" in length which makes this D.E. filter different from others. The 4060 SMBW tank is made with fiberglass-reinforced polypropylene that enhances durability and product life.

Another difference with this D.E. filter is it uses a Noryl rotary backwash valve and is included inside the filter. Most other D.E. filters do not come with a valve but the 4060 SMBW has a built in backwash valve for ease of use. It also comes with a steel tension control clamp rests that securely around the tank and a brass barrel nut securely fastens each half tightly together. To remove the 147411 SMBW 4060 requires a minimum of 58" vertical clearance. Before removing the dome lid, it is suggested to backwash the filter to discharge the contaminated DE powder.

  • The SMBW 4060 carries a manufacturer warranty for 60 days if installed by a non professional or a 1 year warranty if installed by a professional.

Energy Efficient
D.E. Filter systems cut energy costs by using lower pump pressure and speeds. If properly taken care of and rinsed regularly, they can significantly reduce water use. In addition to cost savings, lower pump pressure can help prolong the life of your pool pump!
Low Maintenance
A D.E. Filter maximizes the useful filtration area. A larger filtration area means longer periods between each cleaning, saving you time on pool maintenance and giving you more time to relax and enjoy your pool.
Diatomaceous Earth (D.E.)
D.E. is a natural substance that captures dust, dirt and debris as small as 5 microns. A D.E. filter system removes body oils, suntan lotions, pollens, dust, and even some bacteria, making your swimming pool a healthier environment.
