Sotras filters undergo stringent quality control and are frequently tested in order to ensure satisfactory operation in the application for which they are designed.

Evidence of the high quality of our products lies in the fact that Sotras manufactures original equipment for some of the most important compressor manufacturers, to some of which Sotras guarantees product exclusivity.

Spares for the after market are consequently built to the same exacting standards of components, quality control and tests as those supplied to the compressor manufacturers.

Additionally, the Sotras manufactory quality system had approved certification to UNI EN ISO 9001-2000 (registration n. 926-1) on the 06-06-2003.

We guarantee that filters produced by Sotras are free from defects either in materials or construction, always provided that the machinery is maintained in accordance with manufacturers' recommendations and filters are correctly installed and changed.

Sotras will replace any item found to be defective as described above but will not be held responsible for any other replacement or contingencies or consequential loss.
