Aaf/flanders HR36240 Fiberglass Hammock Filter Merv 4

Product Description

The AAF/FLANDERS HR36240 is a spun fiberglass hammock-style air filter measuring 36 inches wide by 240 inches long by 1 inch thick. Designed without a rigid frame, it suspends freely in media-holding filter banks commonly found in commercial and light-industrial HVAC systems. The HR36240 achieves a MERV 4 rating, making it effective at capturing larger airborne particles including dust and lint. It is rated for approximately 30 days of service life under normal operating conditions. Sold as a single roll, this filter suits high-volume or extended-length filter applications where roll media is preferred over panel filters.

Frameless hammock filters like the HR36240 are typically used in commercial HVAC air handlers, makeup air units, and rooftop units equipped with media-track or channel-frame filter systems. The roll format allows installers to cut the media to length on site, making it a practical choice for non-standard filter bank dimensions or systems requiring continuous roll media. HVAC technicians and facilities maintenance crews commonly specify this type of filter for light-duty pre-filtration duty in large commercial buildings and industrial settings.

Compatibility

Designed as an OEM-style replacement roll media for commercial and light-industrial HVAC filter banks configured to accept frameless hammock-style fiberglass roll filters.

Installation Notes

Installation is typically performed by HVAC technicians or facilities maintenance personnel. Power down the air handling unit before opening the filter access panel and replacing media. Cut the roll to the required length using a straight edge and utility knife. Verify the media track or holding frame is clean and free of debris before inserting new media to ensure a proper seal and prevent bypass.
