VFS 111 24V DC Magnetic Float Switch for RO Water Purifiers

The VFS 111 DC Float Switch for RO Purifiers by Vachan® is a compact and reliable water level control solution developed specifically for domestic and commercial reverse osmosis (RO) water purification systems. Operating on a 24V DC power supply, this magnetic float switch automatically controls water levels inside RO storage tanks, ensuring uninterrupted operation while preventing overflow and dry running.

The VFS 111 uses a magnetic reed switching mechanism with a Normally Closed (NC) contact configuration, providing fast and accurate switching whenever the water level changes. Designed for seamless integration with RO controllers and SMPS units, it efficiently manages pump operation and solenoid valve control to maintain the desired water level. It is also compatible with VFS 107 (NC), making it an ideal replacement or OEM component.

Manufactured using a durable polypropylene (PP) housing, PP foam float, and PU/Epoxy sealed electronics, the sensor offers excellent resistance to moisture, corrosion, and continuous operation in wet environments. Its compact vertical design and 10-inch cable enable quick installation in confined RO tanks and purification units.

Suitable for domestic water purifiers, commercial RO plants, water dispensing systems, and OEM RO manufacturing, the VFS 111 provides dependable performance with minimal maintenance. By automating water level sensing, it reduces manual intervention, protects purification equipment, extends pump life, and improves the overall efficiency of water purification systems. Its compact size, reliable magnetic switching, and long service life make the VFS 111 an ideal choice for modern RO water level control applications.
