The main disadvantages of pressure sprayers are as follows.
(1) A high-pressure pump is required, and therefore, there are certain restrictions on widespread use.
(2) Since the nozzle hole is small, the maximum is only a few millimeters, and it is easy to block. Therefore, the liquid entering the nozzle must be strictly filtered. The liquid pipe of the filter nozzle should be made of stainless steel to prevent the rust from clogging the nozzle.
(3) The nozzle wear is large. For the material with large wear, the nozzle should be made of wear-resistant material.
(4) High viscosity materials are not easy to atomize.
