For customers who need completely grounded or static dissipating cartridges in a cellulose/polyester blend, Environmental Filter now has material in stock to meet NFPA guidelines for grounded cartridges on explosive metals. The media allows the static charge to dissipate from the dust, through the grounded cartridge, making it easier to reverse pulse the dust away from the filters.
In the past, most available materials were not fire retardant so they could not be used in metal applications. Or, you could only get a MERV10 efficiency in Carbon Impregnated Paper or Aluminized Spun bond Polyester.
We now offer both MERV 10 and MERV 15 for laser and plasma cutting (also suitable for the plastics industry where static is generated from processing and conveying the plastic). The Fire Retardant treatment of our media meets the current requirements of F1 Din 53438.
