Herga Internal Air Bellow | 6470-ZZAB
Herga 6470-ZZAB internal pneumatic air bellow for compatible air-button, air-switch and pneumatic control applications used in pool, spa and related equipment systems.
Herga 6470-ZZAB Product Overview
The Herga 6470-ZZAB Air Bellow is an internal pneumatic component used within compatible Herga air-button and air-control assemblies. When the associated button is pressed, the bellow helps create the pneumatic pressure needed to operate a remotely located air switch.
Pneumatic controls are commonly used in pool, spa, hot tub and other equipment applications where the user-facing control is separated from an electrical switching device. The 6470-ZZAB serves as a replacement internal bellow for applications specifically designed around this Herga component.

What Does an Internal Air Bellow Do?
A pneumatic air-button system allows a user to control equipment without placing a conventional electrical switch directly at the control point. Pressing the external button compresses an internal bellow, creating air pressure inside connected tubing.
That pressure travels through the tubing to a compatible air switch, where it mechanically triggers the electrical switching action. Depending on the system, the air switch may control pumps, blowers, lighting or other compatible equipment.
If the bellow becomes cracked, hardened, damaged or unable to create sufficient air pressure, the button may stop operating the connected air switch correctly.
Signs an Air Bellow May Need Replacement
- Air button no longer activates the connected equipment
- Button must be pressed unusually hard to operate
- Little or no air pressure is produced when the button is pressed
- Visible cracking, splitting or deterioration of the internal bellow
- Button operates inconsistently even when the air tubing and air switch are functioning correctly
Compatibility & Replacement Guidance
The Herga 6470-ZZAB should be matched by part number whenever possible. Pneumatic bellows can appear very similar while differing in dimensions, material characteristics or compatibility with the surrounding actuator assembly.
Before selecting an alternative, verify:
- Original Herga part number
- Air-button or actuator model
- Bellow dimensions
- Mounting and seating configuration
- Required pneumatic travel
- Condition of the connected air tubing
- Compatibility with the existing air switch
Frequently Asked Questions
Is the Herga 6470-ZZAB still available?
No. The Herga 6470-ZZAB internal air bellow has been discontinued and is no longer available from Aqua Terra Backyard.
What is the Herga 6470-ZZAB?
The 6470-ZZAB is an internal pneumatic air bellow used within compatible Herga air-button and air-control assemblies.
What does the 6470-ZZAB air bellow do?
When the air button is pressed, the bellow compresses and helps generate an air-pressure signal. That pressure travels through pneumatic tubing to a compatible air switch.
Can I replace 6470-ZZAB with another Herga air bellow?
Not automatically. Internal bellows may differ in size, firmness and actuator compatibility. Replacement should be confirmed using the original part number and application.
Why does my air button click or move but not activate the equipment?
Possible causes include a damaged internal bellow, leaking pneumatic tubing, loose tubing connections or a failed air switch. The complete pneumatic circuit should be inspected before replacing individual components.
Can Aqua Terra Backyard help me find an alternative to Herga 6470-ZZAB?
Yes. Because the original 6470-ZZAB is discontinued, send us the existing part number, photos of the component and air button, and any available equipment information. Our team can help research possible replacement options.
