Performance Systematix Inc. (PSI) was founded in 1984. The founders identified many customers that had unique venting and filtering requirements that most manufacturers thought were too difficult - or unprofitable - to solve. PSI took on the challenge. PSI can take products from concept to market very quickly. We specialize in custom solutions and are able to work with difficult media and substrates. Our highly flexible, yet automated processes allow us to adapt and change to meet our customers' needs.
