We have a wide range of spraying equipment to suit all requirements - here is how to know which one is best for your needs.
Generally the compression sprayers are a smaller capacity, and are carried at the shoulder with a pump at the top. Some of the compression sprayers have optional back-straps so that they can be worn on the back. We now have the entire range of Mesto Cleaner Compression sprayers. These sprayers range from 1 to 10 litre capacity and can work with acid or alkaline solutions or even foaming products.
The knapsack sprayers are larger capacity, are worn at the back and have a handle at the side for pumping. Knapsack sprayers are designed for spraying large areas as opposed to compression sprayers that can be used for any type of job, either large or small. The majority of knapsack sprayers compress the air within the compression cylinder that is inside the tank, not just within the tank itself. This means that you have to compress the tank (pump the handle) far more often and, almost, have to 'pump to spray'. We do, however, have three models that can be pressurised to 6 bar (twice the normal maximum pressure) meaning that, once you are at working pressure, you won't need to pressurise as frequently as a standard model. These sprayers are our RS12, RS18 and RS18 Alkaline.
If you are looking to climb ladders or use telescopic lances with your sprayer, then it may be advisable to consider a compression sprayer (unless you use the RS range) otherwise you will need a hand to pump the tank and another to hold a ladder or two others to hold a long lance. As the average number of hands, per person, is less than two you can understand why using some knapsack sprayers could be awkward.
Check the pH of the chemical that you are using and if you are intending for extended use of acids or alkalines then you can choose chemical resistant equipment. Obviously the pH of a product is not the only consideration when deciding which is the most suited sprayer as it is the main active ingredients that are going to cause any issues. If you need any help selecting a sprayer then just contact us and we will advise on the best options.
