SOLO® 315-A CLEANLine Backpack Sprayer, 4-Gallon

The Solo 315-A CLEANLine is a professional-grade, 4-gallon manual backpack sprayer engineered for the precise and safe application of acidic-based cleaning fluids within a pH range of 1 to 7. Constructed with a transparent, UV- and corrosion-resistant high-density polyethylene tank, it features a 4.5" fill opening and chemical-resistant FKM Viton® seals and O-rings throughout all component contact points. The unit utilizes a smooth piston pump with a 4-stage pressure regulator capable of efficient pressurization up to 45 PSI, isolated within a fully sealed system to eliminate mechanical liquid damage. Operator safety and utility are supported by an integrated steel base frame, an automatic pressure relief valve, wide adjustable padded shoulder straps, a commercial lock-on/lock-off shut-off valve, and a 20" polypropylene spray wand with a built-in retainer handle. It comes standard with a nylon-reinforced hose and four chemical-resistant nozzles, including adjustable, fan, hollow cone, and jet stream configurations.
