Working Principle


The paint spraying equipment for professional contractor are used for airless paint spraying without atomising air . The airless paint spraying equipment is operated by an electric motor, or petrol engine, that transmits its rotating action to an eccentric connected to a piston
dipped in an oil chamber.

The piston with its alternate action sucks the oil pushing it in pressure against the diaphragm, made by an highly elastic and resistant material , that vibrates with the same frequency as the piston. This action creates a depression : the product is sucked and pushed by the diaphragm itself , towards the hose, to the airless spray gun for professional airless applicators

A dedicated valve adjusts the pressure of the oil circuit and the pressure of the product itself.
