WOLF FANS AND DRIVE SYSTEMS

State of the art fan technology for maximum energy efficiency

Choosing the most suitable drive system is of vital importance when it comes to best results. In addition to compliance with standards and regulations, the individual operational requirements are a decisive factor when selecting the ideal system. WOLF offers the optimum solution for every application and provides support during the implementation of your system concept.

EC FANS WITH FREE-RUNNING IMPELLERS

Optimal efficiency and integral control. Exceed the standard by a number of classes with IE4 energy efficiency.

Low air flow rates of up to approx. 30,000 m³/h can be used while various fan wall configurations facilitate scalability. Hooking up several fan units to form a fan wall provides high air flow rates and saves on space, while also introducing redundancy. This kind of fan model is designed to be extremely smooth running and generate virtually no structure-borne noise emissions.

  • Energy efficiency class IE4
  • High system efficiency even in partial load range
  • Integral PID controller for variable output control 0-100 % of the electronically commutated synchronous motors with no power loss
  • Simple and precise output control due to flow rate measuring device
  • Maximum operational reliability and easy maintenance thanks to direct drive
  • Low noise generation
  • Short installed length
  • High outputs enabled by "fan wall"
  • Maintenance-free drive system with low wear and long service life
  • Extremely smooth running, virtually no structure-borne noise emissions

AC/DC FAN
RADIAL FAN WITH FREE-RUNNING IMPELLERS

[Translate to International:] AC PM

In the output range up to approx. 5 kW, the inverter can be fitted directly to the motor for speed control.

  • AC or DC motors for variable output control with inverter
  • Simple and precise output control due to flow rate measuring device
  • Maximum operational reliability and easy maintenance thanks to direct drive.
  • Short installed length
  • Optional versions for ATEX, contaminated extract air
  • Inverter as accessory

Hybrid PM fans

  • Free-running radial fans in compact design
  • Combined with the effect of conventional housed fans
  • Unique air routing and housing geometry
  • Particularly high energy savings

Fan walls

  • For high air flow rates
  • Hygienic, clear of the floor even for high air flow rates
  • Extremely short installed lengths
  • Perfect conveyance of the air flow to the next section (replaces diffuser)
