Developed for OPL laundries where exhaust ducting is directed out toward high pedestrian traffic areas, landscaped areas, and close to HVAC equipment, Wall Hugger series filters keep the property aesthetically free of lint. Filters are installed over duct penetrations on outside walls. Wall Hugger series is unique to the Energenics product portfolio and range in capacities of 3,500 cfm to 14,000 cfm.

Using a configuration exclusive to the Energenics product line, the Wall Hugger dry lint filter employs an exterior application designed to mount directly over the exiting ducts. Historically, hotels have placed on-premises laundries (OPL’s) behind the reception desk, with dryer exhaust venting to the front or sides of the facility. This often results in dryer exhaust venting across pedestrian walkways and a lint mess in hotel landscaping and parking lots. The Wall Hugger series mounts high above the sidewalk, eliminating those issues.

  1. Lint is exhausted from the dryer(s) through the wall and collects on the screen.
  2.  At pre-set back pressure, determined by dryer exhaust CFM, compressed air is released. The compressed air activates the rotor and automatically “blasts” the lint off the screen.
  3.  Lint drops by gravity into the lint bag.
