Ventur JETLINE-315 is an in-line duct fan for general ventilation. The compact, low-profile housing is galvanized steel; an included mounting bracket allows any orientation. The impeller, guide vanes and outlet diffuser are injection-moulded plastic to improve efficiency and lower noise. A single-phase 220–240 V motor with IP44 protection and class F insulation includes manual-reset thermal protection. Nominal duct connection is 310 mm (31 cm), and maximum airflow is rated at 1610 m³/h. Typical uses include supply or extract runs in circular ducting where stable pressure and quiet operation are needed. The JETLINE family also provides gaskets at inlet and outlet to reduce leakage and simplify installation.
