Frequently Asked Questions

What does an air button do?

An air button (also called a pneumatic switch or air switch) activates spa blowers, jets, or pumps without any electrical connection at the button itself. Pressing the button sends a pulse of air through a small tube to a remote air switch unit, which then switches the electrical load on or off. This makes air buttons safe for use in wet spa and pool environments where electrical switches would be a hazard.

What hole size do I need to install this button?

This button requires a 35mm diameter hole in the spa cabinet, surround, or deck. The 45mm top flange sits over the hole to provide a neat, finished appearance. Use a hole saw or step drill bit to cut the correct size hole.

How far can the air tube run from the button to the air switch?

The ASF202 supports an air tube run of up to 20 metres, giving you flexibility in positioning the button relative to the equipment.

Is this compatible with all spa blowers and pumps?

This button is compatible with any spa blower or pump that uses a standard pneumatic air switch system. It is not compatible with electronic touch-pad or digital control systems. If you are unsure whether your equipment uses an air switch, check the equipment wiring or contact us before ordering.
