F-Series Filters
Ideal for use in steel mills, coke plants, pulp and paper mills, foundries, waste industries, aluminum mills, copper smelters, chemical refineries, mining, and other harsh industrial environments, HDT’s Nordic Air® F-Series Filters are highly efficient particulate filters designed for industrial applications. Developed in collaboration with industry maintenance personnel in a wide variety of factory applications, the system features four separate filtering stages and addresses all large industrial filtration requirements.
- Four-stage filtration is required in areas where fine dust, corrosive or harmful gas, lead particulate and other contaminants are found. HDT Nordic Air F-Series Filters are built to withstand these harsh contaminants and to facilitate maintenance. HDT provides a cost efficient solution reducing maintenance time and associated replacement filter costs.
- Stage one filtration incorporates a washable electrostatic filter with 66% average arrestance. Stage two contains a 4" (10.2 cm) disposable filter with 93% average arrestance. Stage three consists of disposable activated alumina and potassium permanganate pellets. Stage four is an absolute (HEPA) filter which is 99.97% efficient on particulates at 0.3 micron and larger.
