Hog Slat Inc. Newton Grove, NC USA July 2021 2 Ventilation Systems Overview The HSIN62990 counterweight inlet is the improved replacement for the legacy 62990 wall inlet. The inlet is made of a more durable door and a lighter, more precisely manufactured frame. It is assembled in a way that allows better sealing. The HSIN4-15 baffle door (replacement for 59296-1) does not have a fiberglass frame and is designed to fit directly into the wall. The inlet’s maximum CFM at a .125” H2O static pressure is about 2400 CFM.
