Mac3
the Unbeatable.
(double-chamber model, SUITABLE FOR : CLEAR AND SEWAGE WATERS, MODERATELY LOADED AND TURBULENT).
In the ’90s, this model revolutionized the float switch industry and has remained unbeaten over the decades. Conceived by Dr. Ronchi, the founder of Mac3, this model gave the company its name and ensured its international success. Thanks to its double IP68 chamber, generous weight, and dimensions, this popular float switch represents excellence in terms of design and functionality. It has been carefully designed to meet the highest standards of quality and safety, providing reliable and long-lasting performance.
Designed and made in Italy.
Designed for
Applications

- Level control in tanks, cisterns for clean, rain, and drainage waters
- High level alarm switch
- Protection against dry operation for low level detection
- ACS certified version for application in drinking water
Features
The MAC3 model was designed to offer optimal performance in a wide range of applications, both in drinking water and wastewater. Some of its features include:
- Absence of roughness: Designed to avoid operational interference due to unwanted friction with suspended solids.
- High buoyancy thrust: This feature is particularly important when dealing with applications with gray waters, where significant loads can occur.
- Double body: To prevent harmful infiltrations, thus ensuring high resistance to shocks.
- Double function for filling and emptying: for application versatility.
These features, combined with careful and uncompromising design, make the MAC3 model a reliable choice to ensure quality and safety in various applications, both for drinking water and wastewater.
