Why is the tank size different from the working capacity?
In order to push liquid out of the tank, pressure must be built up. Room is left within the tank for air, which is pressurised prior to spraying. The difference between tank size and working capacity is to allow for this.
When buying a sprayer, it is worth considering the fact that more pressurised air within a tank means longer spray time before one must stop and re-pressurise the tank. Therefore, the greater difference between tank size and working capacity, the less pumping you will need to do.
It is also crucial to know the working capacity of a sprayer, not just the tank size, as this is the maximum level to which the tank can be filled and still function properly.
