    • Three-phase power supply 400V 50/60Hz in sizes 35 and 42.
  • ModBus communication on RS485 port, communication software provided.

Accessories

  • RPSB - RPSA: anti-corrosive accessory to adapt the rectangular flanged port to the circular pipe. Thanks to the air flow throttle flap, it is possible to regulate the fan performance.
  • RPRB - RPRA: RPSB - RPSA accessory without adjustment flange.
  • TFSB - TFSA: Flange connection with inclined outlet equipped with a protective mesh. Thanks to the air flow throttle flap, it is possible to regulate the fan performance. Flangeless version TEFB-TEFA available.
  • MSGX outlet check valve assembly: gravity-closing fins prevent air from returning to the fan.
  • CPMX PVC engine cover designed to protect the engine against atmospheric agents.
  • SCCX Volute Drain: Circular expulsion sleeve for the discharge of condensation liquid and rainwater. Welded directly onto the fan volute.
  • GTX PVC flexible sleeve: anti-corrosive PVC accessory for connecting the suction/discharge port to the circular pipe of length 160 mm.
