3 Intended use
5
EZR/DZR duct fans are used for air extraction or ventila-
5
tion in domestic or commercial areas. Example: Changing
6
rooms, foremen's offices, workshops, manufacturing
plants, machine or workplace extraction systems, indus-
6
trial halls, laboratories, fitness rooms, restaurants or other
6
commercial premises. Any other or additional use shall be
6
deemed improper.
Operation of the EZR or DZR is only permissible:
6
• for a permanent installation in indoor areas;
10
• if installed on a wall or ceiling with sufficient load-bear-
13
ing capacity;
• with permanent electrical installation;
• with FU mounting foot matching the unit variant;
• between ducts with EL or ELA flexible cuffs;
• with ducts matching the nominal size (folded spiral-
seams duct), Ø 250 to Ø 600 depending on the unit vari-
ant;
• with GP vibration dampers for vibration damping on the
duct system;
• with free contact inlets or outlets with protection
against accidental contact in accordance with EN ISO
13857, for example with the SGR protective grille.

EZR ... B, EZR 25/4 D: single-phase AC versions
DZR ... B, DZR 25/4 D: three-phase AC versions, pole-
changeable three-phase AC versions
5.2 Device features
• Duct fans with nominal diameters Ø 200 - 600 mm.
• Any installation position can be selected. Air extraction
or ventilation, depending on installation position.
• EZR/DZR are speed controllable. Exception: DZR 40/2 B
are not speed controllable.
• Reversing mode permitted. Flow rate in opposite air flow
direction reduced by around 35 %. For reversing switch
→ Internet www.maico-ventilatoren.com.
• Operating capacitor for EZR fans ready for connection in
terminal box.
• EZR/DZR are configured for continuous operation.
If the direction of rotation is changed fre-
quently, the motor may heat up impermissibly →
therefore avoid frequent changes of direction of
rotation.
5.3 Thermal overload protection
Thermal overload protection with temperature sensor in
the motor winding as a standard feature. In case of over-
load/overheating/blockage, the fan is automatically
switched off via an external control device.
Exceptions: Overload protection for pole-changeable fans
and DZR 25/4 D varies depending on the application. Con-
tact us for more information → info@maico.de.
