Mesto Stainless Steel Compression Sprayer - 5 litre
This is a high-quality compression sprayer with a Stainless Steel tank that that allows for a maximum working pressure of 6 bar.
The high strength stainless steel tank allows for a higher than normal maximum working pressure which enables products with a higher viscosity to be sprayed or products which are stipulated to be applied at pressures more than 3 bar. The steel construction also allows for liquids of up to 50oC and is far more robust than a tank constructed from plastic or our polyester coated steel tanks.
As well as a pressure gauge, so that you can see the pressure within the tank, this tank can be connected to & filled from a compressor meaning that you can have a constantly pressurised sprayer. To connect this sprayer to a compressor you will need to use either:
Another bonus with a 6bar sprayer is that if it is used together with our CONSTANT FLOW VALVES you will have a much longer spray time before having to stop work and pressurise the tank. We have a range of 3 Constant Flow Valves which limit the spraying pressure to 1, 1.5 or 2bar. With a potential maximum of 6bar within the tank you can see how your spray time can be increased when the exit pressure is restricted.

This Mesto sprayer is packaged, as usual, in a brightly coloured box with plenty of good quality, informative photos and basic information and is of a construction that felt strong enough to both hold and give some decent protection to the contents. I like the way that the box lid is cut so that it can form a handle. A nice touch.
Upon opening the box, I look for the instruction manual and with these sprayers we get not one but two. The first is more of a leaflet which opens out and gives technical information on metering and spraying rates. It looks very technical but is very informative and a reminder that these sprayers are intended to be used, not just by amateurs but, but professionals. The main instruction manual is printed in six languages so the 47 pages are not of interest to many of us but the 7 that are printed in English tells you everything that you need to know from a welcome message and safety notices through technical information, assembly instructions, care & maintenance information and a faults guide.
Having had a quick read, I decided it was time to have a look at the sprayers themselves. Everything was nicely packed around the tank so to remove the sprayer from the box only required the hose to be put to one side, a gently pull on the tank handle and the sprayer lifted easily from the box. My first impression of the sprayer is that stainless steel makes for a really, very impressive looking tank. I like the brass lance and nozzle and the coiled 2.5-meter hose. This recoil hose reduces the hose length to around 30cm so this is a nice space saving idea which also means that you are not going to get caught up in a long hose. The sprayer itself has three storage holes for lances, a nice big tank handle, pressure release valve, pressure gauge and small storage compartment. These last three are all recessed into the top of the sprayer which kept nice sight lines. This is not important when it comes to the operation of the sprayer but, I feel, it does show that time has been taken to design a sprayer that isn’t just effective but also looks good.
After skimming through the instruction manual, the assembly didn’t look very difficult. There are only three parts to attach to the tank; the shoulder strap, coiled hose and lance. The hose and lance handle are already connected to each other so one less job to do. The padded shoulder strap is fed through the two slots in the rear of the sprayer and whilst a little fiddley, it only took me a few moments to fit. The lance is easily threaded onto the lance handle and the hose screws into the base of tank. TIP: There is a small lock that, when pushed into place, stops the hose from accidentally unscrewing. I would suggest that it is a good idea to use it.
The assembly only took a few minutes and wasn’t difficult. Remember that there are plenty of diagrams and instructions to help you so if something doesn’t make sense then go back to the instruction manual.
I was now ready to start spraying so I placed the tank on the floor and turned the tank handle anticlockwise and after a few turns pulled the central housing from the tank which allowed me to start filling. The design incorporates a nice wide filling area so spillages should be easy to keep to a minimum. I had no issues filling the tank so replaced the housing and gently tightened it. I only needed to pump the tank handle a few times to bring it to full pressure and spraying was just as I would expect; a nice spray pattern was easily maintained. To release the pressure within the tank simply pull the small, red pressure release valve.
Draining of the tank was easy as the hose it attached at the base so, if you wish, you can simply unscrew the hose and the tank will fully drain. Or you can just remove the central housing and empty any contents that way.
TIP: The brass thread, on the lance handle, that the sprayer lance attaches to can be unscrewed which will reveal a larger thread. This larger thread is required should you wish to use telescopic lance extensions or many other types of attachment.
This is a top quality compression sprayer that is designed to be used by both amateurs and professionals alike. The 6 BAR maximum working pressure and the option to pressurise via compressed air (with the addition of a valve) mark these sprayers apart from much of the competition. Metal tanks are very robust and look great.
