Spargers & Pool Bubblers

Air Safety Cushion Sparger (Bubbler) Systemsfor Diving Pools

Natare sparger (bubbler) systems are specifically designed for diving pool applications. These systems create an instant air cushion directly beneath diving boards and platforms to improve diver safety and surface visibility.

Installed in the pool floor under diving areas, sparger systems release a controlled mound of bubbles that:

• Cushion the diver’s impact into the water
• Provide a clear visual reference of the water surface
• Improve safety during high-board and platform dives

Sparger systems are considered an essential feature in competitive diving environments and training facilities.

How a Sparger System Works

An air safety cushion sparger system consists of:

• Air compressor
• Air receivers (storage tanks)
• Stainless steel and PVC sparger diffuser nozzles
• Control valves and regulators
• Filters and air quality components
• Control cabinet and activation system

The sparger diffuser nozzles are installed in the diving pool floor. When activated, compressed air is released through the nozzles, creating a mound of bubbles beneath the diver’s entry point.

The system is activated on demand by a coach or trainer using a handheld remote control. The bubbling action typically lasts between 5 and 7 seconds, allowing proper coordination with the diver’s takeoff and water entry.

Once the diver enters the water, the air flow is stopped.

Designed Specifically for Each Diving Application

Every diving facility has different requirements based on:

• Pool depth
• Diving board or platform height
• Board or platform location
• Required cycle time between dives

Natare air cushion sparger systems are engineered and manufactured specifically for each project. The number, size, and placement of diffuser nozzles are custom-designed to match the diving configuration.

Compressor size, air storage capacity, and cycle performance are selected to ensure adequate air delivery for safe and repeatable dives.

Base-Mounted Compressor and Air Supply System

Typical systems include:

• A high-capacity rotary screw compressor
• One or more vertical or horizontal air receivers rated for 200 psig working pressure
• Manifold components and motorized control valves
• Air storage tanks sized to meet the required dive intervals

Depending on compressor size and air storage volume, dives can typically be completed every 2 to 4 minutes.

Compressors and storage equipment are generally located in a remote mechanical room or service area to minimize noise and optimize space planning.

Air Quality and Control System

A complete air safety cushion sparger system includes a coordinated air quality and control assembly, which may include:

• Pressure-reducing valves
• Air filter regulators
• Electric solenoid control valves
• Pressure switches
• Control panel
• Hand-operated push button remote switch (radio-controlled or cable-connected)
• Non-return check valves for each sparger nozzle line
• Regulating valves for each outlet branch

These components ensure controlled, reliable air release and consistent bubble formation during each dive.

Engineered for Safety and Reliability

Safety and Reliability

Sparger diffuser nozzles are constructed from stainless steel and PVC materials designed for long-term performance in chemically treated water.

Each system is engineered to:

• Deliver precise air flow
• Provide consistent bubble distribution
• Coordinate seamlessly with diving operations
• Support predictable cycle times

Because the system is engineered specifically for the diving pool, performance remains reliable over years of use.

Installation Options

Installation

Natare air safety cushion sparger systems can be installed:

• As part of new diving pool construction
• During diving pool renovation projects

System layout, diffuser placement, and mechanical components are coordinated during the design phase to ensure compatibility with the pool structure and diving equipment.
