The Combi™ 500Ltr Tank System from Streamline® is a compact, professional-grade pure water window cleaning system designed for both vehicle-mounted and static installations. Ideal for domestic and commercial use, it provides a complete cleaning solution with a built-in RO/DI filtration unit, integrated delivery pump, and easy-access control panel — all mounted within a single 500-litre upright baffled tank.

Built with space-saving efficiency in mind, this system includes a stainless-steel mounting frame and can be bolted directly into a van or workshop. It features a high-quality Streamline® 4040 RO Membrane, 11L DI vessel, sediment and carbon pre-filters, and a 100psi 12V delivery pump with digital controller for precise flow management. The onboard pump system draws water from the tank and powers your water-fed pole with consistent pressure.

Key convenience features include two hose reel mounts, inline TDS monitor for quality control, external fill and waste ports, and a secure locking control panel door. The baffled design ensures water stability in transit, while the upright format maximises space in smaller vehicles like the Ford Transit Custom or VW Transporter. For contractors or growing businesses, this setup offers a ready-to-go solution with minimal installation time and full professional performance.

Complete system, ready to go - just add your poles.
