Abstract: The Center of Tribology at the Technical University – Sofia is developing a new functional approach to this problem caused by waste filters, and namely, an approach to increase several times their resource by destroying the contact layer without changing the properties and the structure of the fltering mattrix. The regeneration is accomplished by complex action of physico-chemical, mechano-thermal and hydroacoustic processes, occurring on the external and on the internal surface of the filter, in a multi-phase medium of definite composition and specific dynamic characteristics. The present publication represents the tribotechnology and a complex of 5 devices for identification and renovation of automotive air filters, connected with input and output control, for rough and refined renovation, which have been elaborated in the Center of Tribology. The tribological complex has already been introduced in exploitation in the practice of the ore-mining corporation „Kazahmys”.
