System module i.e. hand tool case, for hand tool storage system, has coupling units for coupling with part of another system module, and ventilator unit generating external utilizable airflow and directly connected with case lid

摘要

The module (10a) has coupling units (14a, 16a) for coupling with a part (18a) of adjacent system module (20a). A ventilator unit (22a) i.e. radial fan unit, generates an external utilizable airflow, and comprising a rechargeable battery interface that receives operation energy from a hand tool rechargeable battery. The rechargeable battery is coupled with the rechargeable battery interface in a tool receiver region. The ventilator unit is directly connected with a case lid (30a), and comprises a rotor that is swingably arranged with the case lid.
