The steam blowers for rooms (VSDU0A0003) are suitable for humidifiers up to 18 kg/h. The steam blower can be fitted directly onto the humidifier, or in a remote position. In the latter case, a support is required for mounting the blower (VSDBAS0001), as well as a steam hose to connect the blower to the humidifier. The steam blower works in ON/OFF mode, and is controlled by a temperature device that is activated when steam is produced. For humidifiers larger than 18 kg/h, the VRDXL00001 steam blowers are available, with 230 Vac power supply; these are designed for installation separately from the humidifier, and require two 40 mm diameter steam hoses.
