Programmable control that adapts to your spa routine

• Multiple speeds provide precise control over intensity, enabling a smooth transition from a relaxing warm-up to a vigorous massage without swapping hardware.
• Purge cycle keeps lines fresh between sessions, reducing odors and maintaining peak air quality and performance.

Intuitive, reliable operation

• Air button with clear feedback offers tactile, immediate activation, while LED indicators confirm power status and the current program at a glance.
• Beefed‑up barb nipple on the air hose connection minimizes the risk of cracking and leaks for a steadier, longer‑lasting seal.
• Compact, bath‑safe design fits neatly behind a tub console or inside a cabinet, delivering quiet performance without clutter.
• Remote control option is available for convenient operation from around the tub or seating area, boosting accessibility and comfort.
