What we do
From equipment selection to system verification
System design
Equipment selection and design of jet fan ventilation and smoke extraction systems for car parks, shopping centres, office buildings and residential complexes.
Discuss your projectCFD modelling
Computer simulation of airflow, temperature and smoke spread to check how the system will perform while it is still on paper.
Modelling examplesHow jet fan car park ventilation works
Compact jet fans replace bulky ductwork under the ceiling. Wolter supplies the complete system: fans, sensors and controls that work as one.
Supply air
Fresh air enters the car park through supply fans or open inlets.
Jet fans
Jet fans mounted under the ceiling create a directed airflow that carries air towards the extract zone.
Extract
Extract fans remove polluted air and, in a fire, take the smoke out by the shortest route.
Sensors & controls
The system adjusts its operating mode on its own and keeps smoke from spreading into neighbouring fire zones.
- No ductwork: more headroom and a brighter, more open space
- Installation, running and maintenance usually cost less than a ducted system
- Escape routes stay clear of smoke for longer
- Smoke exhaust fans tested to EN 12101-3 (classes F300 and F400)
We design
smoke exhaust systems.
We design smoke exhaust systems for buildings of different functions: covered car parks, residential buildings, shopping and office centres, and tunnels.
We calculate the airflow, select the fans and check the layout with CFD modelling before anything is installed.

Modelling jet fan smoke extraction and ventilation systems
We calculate airflow velocity and direction, temperature distribution, age of air and smoke spread in the car park to confirm the system works as designed.
Infrastructure
projects.
Experience across a variety of industries. Since 1972, Wolter has supplied ventilation equipment to infrastructure projects: wind power generation, airports, underground car parks, offshore installations, road tunnels, railway, metro and mass transit (tunnels, stations and platforms), and rolling stock.

Wolter products
Fans for ventilation and smoke extraction
Wolter products have proven themselves in virtually every area of ventilation and air conditioning for residential, commercial and public buildings.
Jet fans for car parks
Ventilation and smoke extraction for underground and multi-storey car parks.
- 300 °C / 400 °C
- 120 min
Two-speed axial fans
Ventilation and smoke extraction, with two operating modes in one unit. AXV series: Ø 315–1600 mm, up to 200,000 m³/h, up to 1,500 Pa.
- 300 °C / 400 °C
- 120 min
- EN 12101-3
Two-stage axial fans
Two counter-rotating stages with separate motors reach about 3,500 Pa. If one stage stops, the other still delivers around 65% of the airflow, so car park extraction keeps running.
Garage extract fans
Two independent fans in one duct housing, fully separated as garage regulations require, with backdraft dampers and fully variable speed.

About Wolter
German engineering since 1971
When developing its products, Wolter pays close attention to aerodynamics, control technology, and the acoustic and vibration behaviour of ventilation equipment.
Wolter GmbH Maschinen- und Apparatebau KG has designed and manufactured fans since 1971. The company serves key markets worldwide through subsidiaries and distributors, and around 80% of its turnover comes from exports.
The complex interplay between these factors in every new project is always of great interest to the company’s engineers. Using the most innovative design tools, including CFD simulation, Wolter offers the optimal solution for any task.
Modern drive and control technology increases efficiency and significantly reduces a building’s operating costs. Aerodynamically optimised impellers and housings keep noise to a minimum.
- Two factories in Germany, headquarters in Malsch
- Quality management system certified to DIN EN ISO
- In-house facilities for factory testing, research and development
- First manufacturer to put carbon-fibre axial impellers into series production
