ROUND DUCT AND FITTINGS COST-EFFECTIVE VENTILATION Considering how high the cost of air processing can be and how rapidly markets are growing, ventilation systems are supposed to meet high requirements. It is necessary, therefore, that ducting systems be airtight enough to keep running costs at reasonable levels. To address this issue, Alnor Ventilation Systems Ltd. has developed a new comprehensive SPIRAL® system. AIRTIGHT DUCTING SYSTEM SPIRAL® is a well-proven system of spirally wound quick-connect ducts and fittings with factoryinstalled EPDM rubber gasket. The gasket ensures a tight...
