WOLTER is a major international supplier of components and complete turn-key systems for car-park ventilation projects based on the induction ventilation principle.

Wolter offers both, axial- and centrifugal-type jet (impulse) fans for standard CO ventilation as well as for smoke-extraction and smoke-control systems.

The range of axial jet fans is certified in accordance with EN ISO 12101-3 for 300°C/2h and 400°C/2h. The jet fans are available with oval- or round-shaped silencer casings, either with long or short casings (for limited installation space). The minimal height of the units allows for the installation where headroom clearance is restricted.

WOLTER axial car-park jet fans are available for uni-directional as well as for reversible systems.

Centrifugal jet fans (JFC-type) are available for temperature class 300°C/2h.

Based on customer requirements, we are able to offer the full range of services and components required to successfully implement a car-park jet ventilation system:

• Assistance with the layout and studies of ventilation and smoke-control scenarios based on Computational Fluid Dynamics (CFD) analysis
• Axial or centrifugal jet fans (impulse fans)
• Main extract and supply fans (AXV-range)
• Control cabinet and automation, integration with the building management system 
• CO gas detection system, optical and acoustic warnings signs, dampers etc.

Experience is paramount when it comes to the planning and installation of a jet ventilation system. Our global reference list stands out. Wolter specialist engineers will be happy to assist you in every way possible – send us your plans or contact us to arrange for a meeting.

WOLTER axial car-park jet fans are available as axial and centrifugal type.
