Spa Builders (SBSG)

Spa Builders air control systems also known as SBSG mechanical or pneumatic control
systems are used in hot tubs and spas to operate pumps blowers lights and auxiliary
functions using air pressure rather than electronic signals.

This category includes Spa Builders air control systems air switches pneumatic
control boxes manifolds and related mechanical control components. Spa Builders air
systems operate by sending air pressure through tubing to activate mechanical air
switches that control spa equipment.

Spa Builders air control systems are commonly found in residential and commercial
spas where durability simplicity and moisture resistance are preferred over
electronic control systems.

Because these systems are mechanical they do not use circuit boards software or
digital communication. Operation is controlled entirely through air pressure and
mechanical switching.

Common issues with Spa Builders air control systems include air leaks cracked
tubing failed air switches worn diaphragms or sticking mechanical components.
These issues are mechanical in nature and are not related to electrical faults.

Spa Builders air control systems are not interchangeable with electronic control
systems and cannot be converted without significant modifications to spa wiring
and equipment.

Before ordering identify the number of air-controlled functions tubing layout and
existing air switch configuration. Matching the system correctly is critical for
proper operation.

If you are unsure which Spa Builders air control system or mechanical component is
correct for your spa do not guess. Text clear photos of the existing air control
box tubing layout and connected equipment and we will help confirm the correct
replacement before you order.
