We should let the operator to inspect the pressure gauge frequently to ensure safe system running.

2. Dont forget why we use filter bags.Basically, we use filter bags to remove the particles and some large size paint cakes from the paint circulation.If we let the possible cakes back to tank,the car body paint quality may be poorer than present case.The paint cakes shown that some abnormality occurs in the tank. One familiar cause is the paint viscosity increased.If we also do not satisfy the paint quality not only the bags life, do not try to change the present using bags types at right.If that,we will complex our problem solve routine.
