Key Pleat® HC - Standard Size Pleated Filters

The Purolator® Key Pleat® HC is a high-capacity, self-supported pleated (SSP) air filter that is suitable for use in HVAC or process air applications with low or medium dust-holding requirements. It is not recommended for applications with very high and/or turbulent airflows, higher operating temperatures or excessive dust-loading conditions.

Purolator's self-supporting media and innovative automated manufacturing process produces consistent pleat shape and spacing in each Key Pleat® HC. The filter’s state-of-the-art media pack is surrounded by a single-piece, beverage board die cut frame, with structural integrity unlike any self-supported filter available today. The Key Pleat® HC can endure impact and deformation and return to its original shape, saving users time and money previously wasted on replacing damaged wire-backed filters.

A seven-strap die cut is located on the air-leaving side of the filter, providing additional strength and durability. In combination, the boxed pleat tips provide more surface area and points of contact for the die cut to be securely glued to the media pack. As an example, the pleat tips are glued to the die cut at more than 250 points on a 24” x 24” x 2” filter.

All Key Pleat® HC filters achieve MERV 8 mechanical efficiency. The sealant used to bond the frame to the media pack is water-repellent, which allows the filters to maintain structural integrity even when wet, preventing delaminating, excessive buckling, or collapsing.

Markets:
Commercial and Industrial HVAC
Process Air Filtration

Applications:
Air handling systems
Rooftop units
Side access housings
Built-up filter banks
Pre-filters in multi-stage systems
Not for use in high temperature environments or applications with very high or turbulent airflow

Benefits
Self-supported media — no metal wire backing means no corrosion or deformation of metal
Consistent pleat shape and spacing allow particulates to collect evenly over the entire surface of the media. Pleat stabilizer straps add rigidity and maintain proper pleat spacing.
Over 250 adhesion points between the media and the frame
Achieves MERV 8 mechanical efficiency
Synthetic media is resistant to moisture, mold, and mechanical damage
Fully incinerable, environmentally friendly disposal
