Types of fluids filterable by polyester filtering discs or stainless steel filtering discs

The filtration systems we manufacture are made of stainless steel, corrosion resistant.
Besides, not all the fluids can undergo filtration process based on discs.

Below we are listing some substances:

• the percentage of the indicated concentrations (for instance 20%) refers to the weights of the substances in the purest status diluted in water
• the percentage 100% refers to the substance in the pure status with percentages of water
