Aaf/flanders HR30240 Spun Fiberglass Hammock Filter Merv 4

Product Description

The AAF/FLANDERS HR30240 is a spun fiberglass hammock-style air filter designed for continuous roll or cut-to-fit filtration applications in light commercial and residential HVAC systems. Measuring 30 inches wide by 240 inches long by 1 inch thick, this filter installs without a rigid frame, making it well suited for media filter housings and custom-size installations where framed panels are impractical. It carries a MERV 4 rating and is rated for approximately 30 days of service before replacement. HVAC technicians and building maintenance personnel typically install and replace this product during routine filter service calls.

This hammock filter is used in applications where a continuous roll of filter media is preferred over individual panel filters. Common installations include air handler units, furnace filter racks, and light commercial HVAC equipment that accept flexible media without a supporting frame. Its spun fiberglass construction targets coarse airborne particles including dust and lint, making it appropriate for pre-filter applications and systems with lower filtration requirements. It ships as a single 240-inch roll, allowing field technicians to cut media to the exact length needed on site.

Compatibility

Designed as an OEM-style replacement or new-install media for residential and light commercial HVAC filter housings and air handler units that accept frameless continuous-roll fiberglass filter media in a 30-inch width.

Installation Notes

Installation is typically performed by HVAC technicians or qualified maintenance personnel. Power down the air handling unit before accessing the filter compartment and replacing media. Cut the roll to the required length using a straightedge and utility knife. Verify proper media tension and seating within the filter rack to prevent air bypass around the edges of the media.
