Product Overview

The Pentair Sta-Rite System:3 Modular Media Filter delivers 450 square feet of filtration area for inground swimming pools, spas, and compatible water features. Its balanced-flow design distributes water across two filtration elements, helping capture debris while supporting longer intervals between cleanings. A durable composite tank and accessible split-tank construction make it a practical choice for professionally designed equipment pads. The top-mounted pressure gauge keeps an important maintenance indicator easy to check. Choose this complete pool filter from Pool Supply Depot for new installations or planned filtration upgrades.

Ideal For

Pool contractors and owner-builders planning inground pool equipment packages, along with service professionals replacing an existing filter after confirming hydraulic requirements, plumbing connections, and available installation space.

Key Features

• Balanced-flow hydraulics distribute debris across the media for more uniform dirt loading.
• Shallow-pleat filtration elements provide substantial dirt-holding capacity and accessible surfaces for cleaning.
• Dura-Glas composite construction provides a durable, corrosion-resistant tank with a matte black finish.
• Posi-Lok clamps and a split-tank design provide access for element inspection and servicing.
• Dual drain plugs support waste drainage and emptying the tank during maintenance or winterization.

Benefits

• Longer filtration cycles can reduce interruptions for routine cleaning.
• Washable media eliminates the need for a backwash valve.
• Replaceable elements allow future media replacement without replacing the entire filter tank.

Compatibility

Suitable for properly sized pool and spa circulation systems using compatible 2-inch connections. Confirm actual pump flow, required turnover, and existing plumbing layout before ordering. Matching connection sizes alone does not guarantee a direct replacement or eliminate plumbing modifications. Compare the inlet and outlet elevations with your existing unit rather than selecting by filtration area alone.

Installation or Upgrade Context

Have a qualified pool professional evaluate the equipment pad and complete installation according to the manufacturer’s instructions. Allow room for lid removal and maintenance access. Confirm required fittings and isolation valves with your installer. Never loosen the tank clamps while the system is pressurized.

Specifications

Customer Q&A

Is this a complete filter or replacement media?
This is the complete filter assembly with inner and outer filtration elements, not a cartridge replacement set. The circulation pump and site-specific plumbing are separate equipment.

Does it require a backwash valve?
No. This model uses washable media and is not designed for backwashing.

How often should the elements be cleaned?
Monitor operating pressure rather than relying on a fixed schedule. Follow manufacturer cleaning guidance when pressure rises 10 PSI above the clean starting pressure.

Can homeowners install this filter?
The manufacturer specifies installation by qualified, licensed personnel because incorrect installation or servicing can create dangerous pressure-related hazards.
