Axial impeller made of conductive plastic. Balance quality of the motor/impeller combination G 6.3 according to category BV-3 in accordance with ISO 14694. The air flow direction is marked.
Standard exhaust air mode, air flow direction with air drawn across motor. Robust three-phase AC motor with ball bearings, maintenance-free. Reversing mode: The volumetric flow is reduced by approx.
35 % with abnormal air flow direction. S1 operating mode (continuous operation). The temperature in the fan motor is monitored by PTC thermistors. The PTC thermistors must be connected to a triggering system (safety device according to Directive 2014/34/EU), that separates the fan permanently from the power if the temperature gets too hot. The MAICO PTC thermistor triggering device MVS 6 or TMS is recommended as the triggering system.Separate terminal box, explosion-proof, with cable screw-connections. A PTC thermistor triggering device is needed to fuse the DZQ/DZS-Ex units. Maico provides the MVS 6 PTC thermistor triggering device and TMS for this purpose. MVS 6 thermistor triggering device.
For monitoring the maximum motor temperature. Type-examination tested according to Directive 2014/34/EU (ATEX). Installation exclusively in non-explosive areas.
TMS thermistor machine protection relay. Suitable for installation in control cabinets. Installation exclusively in non-explosive areasì.
