DRVF-H

The bellmouth is deep-drawn for the best flow properties and therefore enables high aerodynamic efficiency. The shape of the casing guarantees a truly vertical, powerfully guided air jet. Cooling air is supplied to the motor via a duct

  • 7 sizes
  • More than 100 types
  • For a volume flow rate of max. 54,300 m³/h
  • Explosion protection as per ATEX up to Ex II 2/2 G c IIB T4
  • DRVF-H series: max. temp. +60°C in continuous operation
  • DRVF-H series: max. temp. +120°C in continuous operation, suitable for kitchen extract air
  • Satisfies VDI Guidelines 2078 and 2052.

DRV-EC

Energy-efficient, rotary speed-controllable and low-noise due to EC technology. Up to 50% energy savings achievable in practice

  • Controlled ventilation possible (basic and needs-based ventilation)
  • Optionally available with regulation (constant pressure or constant volume flow rate)
  • Simple installation and maintenance-friendly
  • High efficiency, even in controlled mode
  • Rotary speed steplessly adjustable
  • Operating point can be optimally adjusted to the system requirements
  • Simple system balancing
  • A system’s volume flow rate and its pressure can be regulated
  • Cut operating costs
  • Longer service life than conventional motors
  • Unit sizes
  • Volume flow rate V max. 3,700 m3/h
  • Total pressure increase p1 max. 450 Pa

DRV / DRH

Can be assembled at an incline of up to 20° (available for bigger roof pitches upon request). The bellmouth is deep-drawn for the best flow properties and therefore enables high aerodynamic efficiency. The impeller is made of sheet steel, has backward curved blades and is dynamically balanced. The fan has an external rotor three-phase or alternating current motor and a closed design with moisture protection insulation. The motor is fully protected due to guided-out thermal contacts embedded in the motor winding

  • 8 sizes
  • More than 100 types
  • Volume flow rate V max. 32,000 m3/h
  • Total pressure increase p1 max. 800 Pa
