The low-profile design features ICON Touch controls, dual-level LumiLight LED lighting, aluminum mesh filters and Airflow Control Technology (ACT) settings that can limit maximum airflow to 390 or 290 CFM. Zephyr specifies six-inch round vertical ducting. An optional ZRC-01AN recirculating kit and duct-cover extension are sold separately. Verify wall mounting, ventilation and local code requirements before purchase.
