The Vermorel knapsack sprayers use a frame made by Lafuma, a French company famous for making rucksacks. Lafuma’s knowledge and experience clearly shows in this design, which positions the spray tank high on the user’s back to distribute 50 per cent of the weight across the shoulders.
“This has been designed for comfort. And I love the zipped pouch. It’s first class and it will save that embarrassing rummage inside your spray suit when you need your van keys,” says the tester.
The lever on the Vermorel diaphragm sprayer, as on most knapsacks, is left/right reversible but this one is remarkably quick and easy to swap over. Watch closely or you miss it. Additionally, it can be adjusted for height in 10? increments. It pumps on the down stroke and has automatic return. The handle stores upright for safety. “Pumping is tiring, but with this one it is only half the effort because you don’t have to pull it up as well as push it down,” says the tester.
The base of the frame is wide and ensures the sprayer sits squarely and stably on the floor for filling. The cap has a grip bar to aid removal and the filler hole is huge.
The 16-litre Vermorel is robustly built and comes with composite telescopic lance. The electric version is almost identical except there is a motor instead of a lever. The motor works when you press the trigger. We are told the 12V lead battery gives eight hours of use before requiring an overnight charge.
