Solo CleanLine 7 Litre Alkaline Chemical Sprayer

This 7 litre alkaline chemical sprayer has been designed to tackle the tough jobs! The German engineers at Solo got off the chain with this one. Somehow they knew you were going to abuse it. Everything has been over engineered so it can take a hammering! This is a very high quality sprayer that won’t let you down.

The Solo Cleanline 7 litre Alkaline Sprayer is built to handle the pressure! It operates at an impressive 3 bar to provide a strong and steady spray. The pressure relief valve ensures the sprayer won’t get over-pressurised. But the engineers must have figured you’d find a way around that because they’ve made the tank 7 mm thick and put a reinforced 10 Bar hose on it! The pressure relief valve can be manually activated to release the pressure safely from the sprayer before refilling/emptying.

Every component of this chemical sprayer is made from chemical resistant materials. It features special EPDM seals for excellent resistance against alkaline chemicals (pH 7-14) and alcohol based cleaners. In addition to the seals, the tank, pump shaft, check valves, hose, trigger assembly, lance and nozzle are all alkaline chemical resistant. Every part on this sprayer is made from materials that are will not deteriorate from exposure to harsh alkaline chemicals.

The Solo Cleanline 7L Alkaline Chemical sprayer is built like a tank but it’s much easier to drive. It’s been designed for comfortable, all day, everyday use.

The commercial trigger system features a contoured grip and trigger with a quick no drip shutoff valve. It has a quick release locking pin to lock the shutoff valve on for large spraying jobs, or off for safety when not in use.

It comes with an adjustable webbed shoulder strap to reduce fatigue for periods of long use. However, it can comfortably be carried around by the sturdy pump handle. The handle also has a built in holder which keeps the wand in an upright position to prevent drainage when not in use.
