Johns Manville Develops New Air Filter Media

Johns Manville Filtration — a division of the Denver-based Johns Manville Engineered Products Group — has developed Assurance™ with SSP™, a new air filtration media with Self-Supporting Pleat™ (SSP) technology. The new media — a nonwovens composite comprising natural and man-made fibers — is used to produce MERV 6 to 8 mechanical air filters; as well as self-supporting air filters that reduce cost, increase productivity and avoid safety liabilities related to incidents associated with disposal and handling of sharp, expanded-metal filter structures.

Assurance with SSP, suitable for residential HVAC, industrial and commercial applications, is available in customized roll widths and lengths, and offers low-pressure drop and consistent filtration efficiency, according to Johns Manville.

“Our customers have identified that using expanded metal to support the filtration media is a significant and volatile cost and it poses a huge potential liability for them in a number of ways; we’ve addressed these needs,” said J.P. Blanchard, business manager, Johns Manville Filtration. “ Assurance’s Self-Supporting Pleat technology allows filtration manufacturers to reduce costs and increase productivity by simplifying their manufacturing processes through eliminating the use of expanded metal.”
