The Solo CLEANLine 333 FA foam sprayer is a professional-grade cleaning tool manufactured in Germany, designed for reliable performance with neutral and acidic cleaning agents. This foam sprayer features a 4-liter capacity tank constructed with extremely stable pressure-resistant walls measuring 7 mm thick, ensuring durability during regular use. It incorporates acid-resistant FKM seals that make it suitable for cleaning solutions within a pH range of 1-7, accommodating both neutral and acidic formulations. The unit includes an extra-large piston pump that generates working pressure with just a few pumping strokes, reducing user effort during operation. A stable fabric hose with an ergonomically shaped handle provides comfortable control during extended cleaning sessions. The Solo VarioFAOM foam sprayer system offers patented stepless foam adjustment through a rotating setting wheel, allowing precise control over foam density according to cleaning requirements. The sprayer comes in a white color finish and is supplied as a single unit. This model represents the successor to previous foam sprayer designs, maintaining Solo's reputation for quality German engineering in outdoor maintenance equipment.
