We recommend that genuine Pentair Clean Air Systems Parts (Goyen/Mecair) kits be used on all reverse pulse-jet cleaning systems that have been fitted with Goyen/Mecair valves and associated components. The genuine kits have been designed to maintain the performance of the cleaning system and ensure longevity of all parts that form the system. Using other non-genuine parts could result in premature failure and costly unplanned plant shutdowns for further servicing. In our experience using non-genuine Goyen/Mecair parts usually results in the customer having to replace the parts at a later stage with the genuine parts in any case.
