The large air vents, equipped with a nut and O-ring, are designed to equalize temperature and pressure while preventing internal condensation. Constructed with a gray polycarbonate body (UV stabilized for outdoor use) and a gray ABS nut, the small variant (UA-022) is recommended for a mounting hole size of 2.48" (63mm), while the large variant (UA-023) suits a hole size of 3.46" (87.9mm). These vents are well-suited for larger ZH Series, ZQ Series, WQ Series, and SB Series enclosures. The small vent is compatible with most 60mm fans, while the large vent accommodates most 80mm fans. M4 thead forming screws can be used to mount fan to vent (fans and screws not included).
