Dmark, Inc. has been in business since 1970 and over that time has developed a number of high performance carbon based and filter media based products to work in almost any application and especially in conjunction with air moving, HVAC and air handlers for buildings of any size.
The Ring Panel Filters offered by Dmark consist of an outer panel of polyester layers to remove particulate with an inner core of CarbonWeb filter media containing 60% activated granular carbon which removes odors and gaseous pollutants. This dual-action ring panel filter comes in a variety of sizes to fit any duct configuration and custom sizes are available upon request.
For people working in an environment where high levels of airborne particles and odors or gases are present, the Dmark OdorGuard ring panel filters are the best solution with high performance at a very low cost.
These filters are easy to install and usually replace the existing box framed air filter located on the return air side of the HVAC systems. These filters will are significantly more efficient than the general duty air filters and can make a significant difference in creating a healthier work or home environment.
The ring panels are offered with 3 different amounts of carbon per square foot. The lighter version has 45 grams per square foot and is more likely to be used in a residential application. The medium duty ring panel has 300 grams of carbon per square foot and the heavy duty ring panel has 345 grams of carbon per square foot. The last two are normally used in the commercial or industrial applications.
These filters also have a MERV rating of between 8 and 9. This is very good for reduction of large quantities of smaller airborne particulate.
