Tuning Airblast Sprayers
We tend to take the blowers for granted. The propeller blades just keep turning and blowing the air, but what we don’t realize is that they need to be checked periodically and cleaned, to remove the residue that cakes up on the surfaces and makes them less efficient.
There can also be nicks and cracks caused by picked-up debris and fatigue, which can throw the propeller out of balance and produce vibrations. These vibrations usually affect the chassis and the tank to the extent that I have seen steel tanks crack and break or pumps break loose because of those vibrations.
So, when you’re cleaning out filters, inspecting hoses and checking nozzles, take a good look at the blower: clean the blades (you may have to scrape them), tighten the bearings, lubricate the moving parts and check for loose bolts and broken brackets.
