Parker LoadTECH 4-inch MERV 15/15A extended rigid cell filters use E-Pleat media technology for commercial and industrial HVAC systems, including variable air volume systems. The gold-tinted, 100% synthetic media has an embossed, two-layer gradient-density structure. Preformed channels guide air through the filter for even dust loading and full use of the media. Parker lists schools, universities, hospitals, healthcare facilities and clean manufacturing facilities among the applications for this family.

Adhesive beads bond the pleats into a rigid pack, and a high-impact polystyrene frame resists moisture, chemicals and corrosion. Foamed hot-melt adhesive seals the media pack to the frame to prevent bypass at that joint. The frame corners mechanically lock together. Low pressure drop supports reduced energy use, while high dust-holding capacity supports longer filter life and fewer changeouts.

The family includes box/no-header and single-header configurations. Single-header models have a 3/4 x 3/4-inch header on the air-entering side. Gaskets are optional, and special sizes are not available.
