Hall ventilation

Clean air in production halls.

Using a holistic hall ventilation system is unavoidable in many applications in order to protect the legal provisions and to protect employees. Depending on the application, these can be added to existing extraction devices or installed as a central suction unit.

ESTA has developed two different processes for hall air extraction- Push Pull mixed ventilation and Upstream layered ventilation. In both cases, a central extraction unit is used, e.g. the ESTA DUSTMAC installation. It is installed in the interior of the hall or outdoors and is connected with an extraction and feed air pipeline. 

In both systems, we can offer you a customer-specific, software-supported and energy-efficient design. By using tried-and-tested ESTA filter technology, we minimise the pollutant loads for employees and at the same time we optimise the climatic conditions in your productions using automatically-regulated supply of fresh air including cooling and heating. This results in a noticeable reduction of your energy costs.

The working principle of hall ventilation

Procedure

Push Pull mixing ventilation

 

In mixed ventilation, the clean air is fed into the upper area of the hall via jet nozzles which has the effect of mixing the air in the hall.

  • Hall height < 7.5 m
  • Low thermal loads < 10 tons / year welding wire consumption
  • Feed nozzles with high jet range
  • Two pipeline rods opposite each other
  • Suitable for cooling and heating
  • Also designed for dust and odours

Upstream layered ventilation

 

In layered- or displacement ventilation, the clean area is fed through source vents close to the floor. This provides support for the thermal upswing of welding fumes.

  • Hall height ≥ 7.5 m
  • High thermal loads > 10 tons / year welding wire consumption
  • Displacement outlets close to the floor for generating a layer of cold air
  • Sensors for continuous temperature measurement and fully-automated control of the proportion of fresh air
  • Low air volume flows are sufficient
  • Suitable for cooling and heating
  • Given appropriate thermal loss and suitable for dust and odour

PRODUCT OVERVIEW

Use the DUSTMAC-series to implement individual installation concepts for central multi-location extraction. Depending on the type of dust, volume, incidence and composition of the dust, the appropriate filters are used in the filter housing.

The modular welding fume filter WELDEX FE is ideal for extracting large volumes of air from 20,000 to 120,000 m³ / h and can be used both for direct extraction and as a hall ventilation system.

As an alternative or supplement to direct extraction, the free-standing Plug & Play hall ventilation system FILTOWER is suitable. It captures dust, fumes etc without pipelines.

Modular central extraction system for almost any location and industry.

Hall ventilation system optimises the workplace environment

A hall ventilation system is necessary to achieve an appropriate temperature and clean air in the working environment. Good environmental conditions mean obtaining the right mix of air quality and air temperature, as well as humidity. An appropriate combination of extraction systems can result in a regulated fresh air supply, including cooling and heating, and improvements in energy efficiency. It is not only a matter of compliance with relevant legislation, but also the reduction of energy costs.

ESTA’s two proven air extraction processes

ESTA has developed two extraction processes to achieve air extraction in machine or production halls, where a vast array of manufacturing processes may take place. With the ESTA Push Pull mixed ventilation, contaminated fumes rise and clean air is fed into the upper area of the hall via jet nozzles, which mixes the air in the hall. The air is suctioned through a pipe and led to the filtration unit, from which the clean air is redirected to the supply air system. With the ESTA upstream layered or displacement ventilation system, the clean air is fed through source vents close to the floor instead. Both systems require a central extraction unit which can be installed in the interior of the production hall or outdoors and is connected with an extraction and feed air pipeline.

Central extraction systems

The configurable and modular ESTA DUSTMAC series can be employed as an extraction system. It filters all kinds of dust and its filters are adapted to the type of dust filtration required. The modular welding fume filter WELDEX FE is ideal for extracting large volumes of air from 20,000 to 120,000 m³ / h and can be used both for direct extraction and as a hall ventilation system. Where space is limited and pipelines are out of the question, the free-standing FILTOWER Plug & Play hall ventilation system is an alternative or supplement to direct extraction. The FILTOWER filter tower can capture many forms of dust, smoke as well as oil mist. It is ideal for welding, soldering, grinding, polishing, machining and milling processes. It just needs connection to the mains, compressed air and it is ready to start work on improving air circulation. It excels with its low-noise, straightforward handling and trouble-free maintenance.

Excel beyond statutory limits

By providing efficient air circulation, manufacturing companies can comply with statutory regulations governing this aspect of occupational health and safety. Going further, by promoting and acting to provide a comfortable working environment, with the latest in industrial ventilation and extraction systems, will no doubt result in additional benefits including lower operational costs and improved output.
