# 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.
