short description

Axial wall-mounted fan with steel wall ring, DN350, three-phase AC, explosion-proof, medium: dust

Product description

Product model

  • Three-phase AC motor
  • Ex II 2D Ex tb IIIB T135°C/T200°C Db IP64 X / Ex II 2D Ex h IIIB T135°C/T200°C Db X.
  • For usage temperatures of -20°C ≤ Ta ≤ +60°C.
  • Can be switched to ventilation or air extraction.

Special features

  • Axial wall fan, explosion-proof, medium: dust.
  • Explosion protection and approvals in accordance with ATEX and IECEx.
  • Qualified for all dusts of the Ex-group IIIA and IIIB.
  • MAICO Ex fans fulfil the safety requirements of European Directive 2014/34/EU for units and protective systems in potentially explosive atmospheres.
  • For zones 21 and 22.
  • Types of ignition protection: “t” - protection through housing and “c”- constructional safety.
  • IP 64 degree of protection.
  • Protective grille on the intake side, protection against accidental contact in accordance with DIN EN ISO 13857.
  • Can be fitted in any position.

Model series

  • EZQ / DZQ .. Ex t with square wall plate.
  • EZS / DZS .. Ex t with steel wall ring.

Impeller

  • 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.

Air flow direction

  • The air flow direction is marked.
  • Standard exhaust air mode, air flow direction with air drawn across motor.

Three-phase AC motor

  • Robust three-phase AC motor with ball bearings, maintenance-free.
  • Reversible.
  • Reversing mode: The volumetric flow is reduced by approx. 35 % with abnormal air flow direction.
  • S1 operating mode (continuous operation).
  • Speed control permitted with TR... transformer. Exception: DZ.. 35/2 B Ex...
  • 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.

Electrical connection

  • EZ .. Ex ..: Connection cable, approx. 0.5 m long.
  • DZ .. Ex ..: Connection cable, approx. 1.7 m long.
  • Separate terminal box, explosion-proof, with cable screw connection.

DZQ/DZS Ex .. required safety technology.

  • 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.
    • Independent complete system.
    • 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.
    • For monitoring the maximum motor temperature.
    • Suitable for installation in control cabinets.
    • Type-examination tested according to Directive 2014/34/EU (ATEX).
    • Installation exclusively in non-explosive areas.

Special versions

  • Special voltages are available as special versions on request and at extra cost.
  • Information on operation at temperatures occasionally below -20°C available upon request.
  • Feasibility must be checked in each case.
