Swimables SW-28-200 Jandy-Style Air Relief Assembly

Safely Release Trapped Air and Protect Your Pool Filter

The Swimables Jandy® Style Air Relief Assembly (SW-28-200) is a replacement air relief assembly designed for Jandy-style pool filters. The air relief assembly allows trapped air to be safely purged from the filter tank during startup, preventing pressure spikes, inaccurate pressure readings, and unsafe operating conditions.

A properly functioning air relief assembly is critical for filter safety, system performance, and long-term equipment protection.

This product is a pool filter air management component, engineered specifically for swimming pool filtration systems.

What an Air Relief Assembly Does

When a pool pump starts, air trapped inside the filter tank must be released before full water pressure builds. The air relief assembly:

• Releases trapped air during system startup

• Helps prevent pressure surges

• Allows accurate pressure gauge readings

• Protects internal filter components

Without a working air relief assembly, air can remain trapped, leading to poor filtration and potential equipment damage.

Designed for Jandy® Style Pool Filters

The SW-28-200 air relief assembly is manufactured in a Jandy-style configuration, making it compatible with many Jandy-style DE and sand pool filters that use a top-mounted air relief system.

It is commonly serviced alongside parts found in the Pool & Spa Filters Collection and Pool Filter Replacement Parts Collection.

Always verify filter model and OEM part compatibility before ordering.

Common Signs an Air Relief Assembly Needs Replacement

A failing air relief assembly can cause several noticeable issues, including:

• Air trapped in the filter after startup

• Pressure gauge not reading correctly

• Water spraying or leaking from the relief area

• Difficulty bleeding air from the system

• Cracked or seized relief components

Replacing the assembly restores safe and proper filter operation.

Protects Filter Internals and Improves Safety

Trapped air inside a filter tank can compress and expand rapidly, creating unsafe pressure conditions. A functioning air relief assembly helps:

• Reduce stress on filter housings

• Protect internal manifolds and grids

• Improve system startup safety

• Extend overall filter life

This makes the air relief assembly a critical safety component—not just a convenience feature.

Built for Pool Filtration Environments

The Swimables air relief assembly is constructed from pool-rated materials designed to withstand:

• Continuous water pressure

• Chlorinated and saltwater pools

• Outdoor temperature fluctuations

• Repeated manual operation

This ensures reliable performance throughout the pool season.

Ideal for Filter Service and Rebuilds

Air relief assemblies are commonly replaced during:

• DE filter rebuilds

• Pressure troubleshooting service calls

• Seasonal equipment inspections

• Manifold or grid replacement jobs

Service professionals often replace air relief assemblies preventatively when filters are already disassembled.

This component pairs naturally with DE filter manifolds, grid assemblies, and filter O-rings found in the Pool Equipment Parts Collection.

Installation Notes

General installation considerations include:

• Depressurize system before removal

• Remove old air relief assembly carefully

• Inspect mounting port and threads

• Install new assembly snugly without overtightening

• Test for leaks during startup

Professional installation is recommended for optimal sealing and safety.
