Product Overview
The Pentair Sta-Rite System:3 Modular Media Pool Filter provides 500 square feet of filtration area for inground pools, spas, and compatible water features. Its balanced-flow design and integral manifold distribute water across the media to support uniform dirt loading and longer cleaning intervals. A durable Dura-Glas composite tank, washable elements, and accessible split-tank construction make this complete filter a practical choice for professionally planned equipment installations and filtration upgrades from Pool Supply Depot.
Ideal For
Inground pool construction, equipment-pad upgrades, and replacement projects where contractors or owner-builders need substantial filtration area and serviceable media without a backwashing system.
Key Features
- Balanced-flow hydraulics help distribute debris across the media rather than concentrating it in one area.
- Shallow-pleat elements provide accessible cleaning surfaces and substantial dirt-holding capacity.
- Dura-Glas composite construction provides corrosion resistance with a matte black finish.
- Posi-Lok clamps, a top-mounted pressure gauge, and dual drains simplify inspection, monitoring, and servicing.
Benefits
- Longer filtration cycles can reduce maintenance interruptions.
- Washable media eliminates routine backwashing and the need for a backwash valve.
- Replaceable elements allow worn media to be renewed without replacing the entire tank.
Compatibility
Designed for appropriately sized pool and spa circulation systems with compatible 2-inch connections. Confirm actual pump flow, plumbing layout, and required turnover before ordering. Matching pipe size does not guarantee direct replacement or eliminate the need for plumbing changes.
Installation or Upgrade Context
Installation should be completed by qualified, licensed personnel. Provide adequate clearance for lid removal and media servicing. Never loosen the tank clamps while the filter is pressurized.
What’s Included
Complete filter assembly with inner and outer media elements, tank clamps, pressure gauge, and air-release valve. The circulation pump and site-specific installation plumbing are separate.

Customer Q&A
Does this filter require sand or D.E. powder?
No. It uses washable modular media elements rather than sand or D.E. grids.
How often should the media be cleaned?
Follow the manufacturer’s cleaning procedure when pressure rises 10 PSI above the clean starting pressure. Water conditions and debris loading affect cleaning frequency.
What does the 62,400-gallon turnover figure mean?
It represents eight hours of filtration at 130 GPM, not a universal pool-size recommendation. Actual sizing depends on system flow and required turnover.
Can it replace a smaller filter?
Potentially, after a professional checks the plumbing, pump output, equipment-pad dimensions, and service access. It is not a universal drop-in replacement.
