Clean hall air directly from the manufacturer
A hall extraction system or hall ventilation system is used for automatic air circulation, heat regulation and filtering of welding fumes, fine dust or oil mist from the hall air. This can be done via a central hall extraction system with a permanently installed pipe system or mobile filter towers.
The contaminated exhaust air is drawn in and welding fumes, dust and other emissions are efficiently filtered through several filter stages. Innovative heat recovery can preserve up to 70% of the thermal energy and drastically reduce energy costs. In order to provide our customers with an economical and energy-efficient hall ventilation system, we take numerous parameters into account and plan our solutions individually for the respective application, including the pipe system and installation.
- Central ventilation control and high air quality
- Extraction of several workplaces at constant extraction power
- Most effective protection against industrial emissions without interrupting work
- Fully automatic operation
- Draft-free and low-noise airflow
- Automatic Jet-Pulse cleaning
- Individual unit color and branding
- High-quality products »Made in Germany«
- Low operating costs
- Heating cost savings of up to 70 %
- Flexibility for future hall use
- Increase productivity and health
- Compliance with occupational health and safety regulations
When is hall ventilation needed?
- Large workpieces
- Workplaces far apart from each other
- Medium to large quantities of smoke/dust
- Point extraction not possible or sufficient
- Environments with changing dust/fume sources
Air exchange can take place via recirculation, exhaust air operation or in combination with fresh air. Recirculated air operation is particularly useful in combination with heat recovery.
Centralized or decentralized extraction?
Central extraction systems for hall ventilation can be much more efficient and economical than selective collection, especially in large production halls. Several workplaces are kept free of smoke and dust at the same time with constant extraction power. The air is cleaned centrally via an extraction system. This saves costs of daily operation, for energy and spare parts such as filters
The constant high air quality and the fully automated operation also reduce handling to a minimum and thus facilitate the daily work of your employees – because maximum emission and occupational safety is also possible with ABSAUGWERK without interrupting work.
Outdoor or indoor installation?
We adapt every hall ventilation system to your needs. All dry extraction systems from ABSAUGWERK are suitable for both indoor and outdoor use. Do you have little space in the hall or do you want to do without a complex pipe system?
We will advise you individually and find the most economical solution together.
The differences in the nature of production halls and the procedures and processes that take place there require an individual ventilation system and careful planning for each hall ventilation. Depending on the number of workplaces and the daily working hours, emissions such as smoke, dust or oil mist develop in varying quantities. If these released media are respirable, carcinogenic or explosive, this must be taken into account when choosing and numbering the filters. As a professional manufacturer of hall ventilation systems, we take all relevant parameters into account:
- Area, room volume and ceiling height
- Construction type of the hall
- Process (welding, grinding, sawing, deburring, etc.)
- Material type and quantity (carcinogenic, respirable, explosive)
- Emission development (strong, medium, weak)
- Point extraction available
- Simultaneity of extraction
- Working hours and shift operation
- Refurbishment or new construction
- Recirculation/exhaust air operation
- Pipe system progression
- Cleaning intervals and times of the filters
- Capture elements
- Discharge systems
- Installation location and space requirements
- Air flow course

Techniques hall extraction
As a manufacturer of extraction systems and hall extraction, we supply holistic systems from a single source. This includes: Capture, piping system, exhaust system and other equipment. Integrate point detections such as extraction tables, extraction hoods or extraction arms. Optionally, we also offer cross heat exchangers, continuous mixing of fresh air and individual solutions for your application.
In push-pull mixed ventilation, the purified air is introduced through jet nozzles of the supply air pipe on the hall ceiling and drawn in on the opposite side through exhaust nozzles of the exhaust air pipe and filtered in an exhaust system. Mixing of the hall air occurs mainly in the upper third of the hall, where the warm air containing pollutants collects.
In Push-Pull Plus systems, additional air source emitters on the floor support the intrinsic thermal properties of the welding fumes. The contaminated air rises more quickly and is captured at the hall ceiling, passed through an exhaust system via a pipe system and filtered.
In the principle of layered ventilation, the cleaned air is supplied via displacement outlets close to the floor. The fresh air mixes again with pollutants, heats up and rises upwards due to its thermal properties, where it is extracted via the exhaust air pipe on the hall ceiling and cleaned in an extraction system.
The principle of layered ventilation is also recommended by the IFA (Institute for Occupational Safety and Health of the German Social Accident Insurance). For more information, visit www.DGUV.de/ifa
Inverse Layer Ventilation:
The inverse layer ventilation works laterally reversed in contrast to the layer ventilation. The purified air is blown towards the floor via jet nozzles of the fresh air duct on the hall ceiling. There, the clean air mixes with the polluted air and is collected again near the floor via extraction columns or extraction hoods and filtered in an extraction system.

Oil mist/emulsion mist
Save energy and heating costs!
Constant air quality and constant air circulation significantly improves the hall air and can save up to 70% on heating costs.
Individual hall extraction for every application
We configure an optimal hall extraction system for you and are your reliable partner not only until commissioning, but also in maintenance and service issues: Quality directly from the manufacturer.
Filter towers for hall extraction
Filter towers can provide a quick remedy for welding fumes, oil mist and fine dust in production halls. The extraction units are placed in the hall without a fixed pipe system and require only 1.25 m² of floor space. At the same time, the filter tower provides automatic heat regulation in the production hall and can save up to 70% in heating costs. By using a HEPA H14 filter, the filter tower also serves as a hall air purifier and efficiently filters minute particles such as viruses, spores and pollen from the room air.
Our filter tower was developed according to the Plug & Play principle and is ready for use within a few minutes: Storm + compressed air = off you go!
