Both as a combination with an extraction and air purification system, as well as an independent system, AFS air supply systems are always perfectly designed o the needs in a production hall.

Whether in new buildings or in existing halls, the advantages of an AFS air supply system are obvious:
- conditioned and filtered supply air enters the hall all year round
- a defined air exchange in the hall is ensured
- odor-laden and possibly warm and humid exhaust air is led into the open air
- AFS air supply systems can be completely used for heating (additional heaters are not necessary)
- AFS air supply systems are energy-efficient and designed according to the latest energy-saving regulations
- AFS supply systems are eligible

AFS can rely on many years of experience in the field of air and ventilation technology in manufacturing plants. Particularly in manufacturing plants, many things such as e.g. crane paths, machine park, heat development of machine tools, logistics routes, etc., it is advisable to rely on the experience of AFS.

Industrial processing installations and the use of special coolant lubricant oftentimes lead to increased odors in the workplace. This is frequently accompanied by contamination of the air with hazardous materials. Particularly the high concentration of hazardous materials in the gas phase contributes significantly to air pollution. Special air purification processes are required for filtering pollutants from the gas phase and process air.

The AFS air purification devices with attached active carbon box combine different applications into a single device:

The efficient separation of aerosols, mist, vapor and smoke is combined with downstream active carbon filtration for purifying the exhaust air of hazardous materials and odors.

The AFS 400 C and AFS 1000 C are two such air purification devices with exhaust volumes of 400 m³/h and 1000 m³/h, respectively. If higher exhaust volumes are needed, we are also happy to provide you with individual solutions.

Open machine tools present a great challenge regarding the aspiration of the oil or emulsion mist, in particular if the machine tools are very large and / or have large travel distances.
AFS extraction systems for large and open machine tools are the solution.
The special designed hoods significantly increase the aspiration range compared to conventional aspiration points (such as a standard pipes, hoods, etc.). The high-performance and efficient AFS air purifying units ensure the required volume flow and the required pressure difference (see also section "AFS air purifying units").

Compared to single extraction units, where the mist of a machine tool is extracted and purified by one single mist collector, central extraction systems are clear advantage for extraction and air purifying of multiple machine tools:
The individual machine tools are connected via a pipe system with a centralized AFS air purification device .
The purified exhaust air can then be blown as exhaust air directly outside or as circulating air back into the hall. Managing the exhaust air and the associated air exchange reduces the relative humidity, heat and odors in the production hall.
Alternatively, the purified exhaust air can be routed to an HVAC system with heat recovery. A heat exchanger recovers residual heat from the exhaust air, which is then used to preheat the air supplied from the outside. HVAC systems are also used to condition the hall air.

AFS central purifying systems should always be viewed as an integrated approach. This allows the use of additional heat sources, like thermal discharge from compressors, to be integrated into the overall concept.

Using a duct system, the purified outgoing air is routed to an HVAC system and blown to the outside year-round as outgoing air. When necessary, a heat exchanger in the HVAC system mostly draws the residual heat from the exhaust air and uses it to preheat the cool outside air.

The outside air, which is aspirated by the HVAC system, is filtered and (when necessary) preheated by the heat exchanger. If the preheating in the heat exchanger is insufficient (e.g., lack of heat in the outgoing air or when outside temperatures are extremely cold), then a reheating register also heats the outside air to the target temperature. The supply air can be air-conditioned by an additional cooling register in the HVAC system. The supply air is then routed to the hall by way of a defined duct system and distributed evenly and draught-free through outlet louvres or air diffusers.
Exhaust and supply air systems are operated automatically using intelligent control and adjustment technology. Time programs enable different operating modes. Protecting the hall from cooling down during production downtimes can also be achieved as well as nighttime atmospheric cooling in summer.
Using an AFS exhaust system with supply air system, clean, pollen-free and dust-free air that is optimally conditioned for the hall is supplied year-round.
