Product Information

Dominator® is a high-efficiency, low initial pressure drop, rigid cell produced in both 4" and 12" depths. Two efficiencies are offered in each depth: MERVs 11 and 14 in the 4" depth and MERVs 11 and 15 in the 12" depth*. In either configuration, the Dominator will improve fine airborne particulate removal while maintaining, or reducing, your energy consumption and costs.

Glue Bead Adhesive Strips Stabilize Pleat Pack - Beads of adhesive applied to the media bond the pleats into a totally rigid, solid pack. The pleats hold their shape and the molded channels are held open for free flow of air in all types of operating conditions. No pleat deformation, no blocking off.

Rigid Cell Design Handles Difficult Operating Conditions - Rigid cell design, all plastic components and 100% synthetic media make Dominator filters ideal for the most demanding operating conditions, including variable air volume systems, high air flow, turbulence, repeated fan shut down, high moisture, and some chemical or corrosive conditions. These filters are designed for tough installations.

Full Media Exposure Produces High Dust Holding Capacity - The E-pleat design not only produces low resistance, it also allows the media to be completely exposed to dirt laden air. Dirt loads evenly over every square inch of filter surface area for maximum dust holding capacity and long service life.

100% Synthetic Media - Dominator filters are made with 100% synthetic media. It is extremely durable, resists tearing, abrasion and is highly damage resistant. No more media damage during shipping, handling or installation. Dominator media is also unaffected by exposure to moisture and some chemicals. This media is just plain tough.
