Filter Applications Equipment Solutions for Filter Manufacturing On-ratio adhesive dispensing – for less waste and more uptime • Reliable dispensing equipment for end cap molding, sealing and media bonding • Ratio assurance results in less material waste, higher yield, reduced scrap and more process confidence • Easy to program and store multiple shot sizes and sequences • Accurate, repeatable shot and bead dispensing • Wide ratio range – 1:1 to 32:1 – lets you switch materials and maintain ratio • USB interface lets you download process data onto a flash drive to verify the material was dispensed accurately and on-ratio

Increase Process Confidence with On-Ratio Dispens Reduce scrap and material waste When you’re using plural-component materials for bonding and sealing filters, ratio accuracy is a critical part of the manufacturing process. Without proper ratio assurance, you face the expense of wasted material, scrapped parts and re-work, increased operating costs and reduced profitability. Graco equipment for filter bonding applications is designed for accurate, on-ratio dispensing. With a pressure transducer option, you have the assurance and peace of mind that your material is dispensed properly and on-ratio....
