CEFIL’AIR® Inflatable Seals

Pneumatic seals offer the easiest, safest and most effective way of sealing parts that move in relation to one another and need to be connected and disconnected. CEFIL’AIR® seals, which are expanded and retracted by a pneumatic process, feature a patented design that employs advanced elastomers and modern manufacturing techniques to meet the requirements of numerous applications.

BIO-GUARDIAN® SEALS: essential to the medical, pharmaceutical and food industries, the BIO-GUARDIAN® sealing solution prevents bacterial and microbial growth on equipment and materials. The BIO-GUARDIAN® solution can be used in CEFIL’AIR® inflatable seals to meet the needs of demanding hygienic applications.
