Purpose
GAB and GAPF cabinets do the same job as the GAES/GADS duct units — extract by two independent fans — but for higher airflow. The fans in the cabinet are fully separated, as the garage rules require.
GAPF
Direct-driven plug fans (free-running impellers without a scroll). The three-phase IEC motors are designed for inverter control, the single-phase ones for a step transformer. Self-acting dampers go on the pressure side, and a measuring ring in the inlet nozzle allows the airflow to be checked. Interchangeable side panels let the cabinet stand in a corner.
GAB
Two forward- or backward-curved fans, belt-driven (TRZ/HRZ), or direct-driven fans with external-rotor motors. In GAB-H the H means the fan housings are side by side. Airflow is approx. up to 100,000 m³/h.
Casing options
Extruded aluminium frame with galvanised insulated panels; epoxy coating or double skin on request. A weatherproof version is available for outdoor installation.
