Fumes, dust and shavings
The ventilation of industrial manufacturing processes is often forgotten, but it is a very important process. The reasons for ventilation range from the prevention of odours to the removal of toxic gases. The reduction for cleaning and maintenance requirements is also a reason. A powerful extraction unit can prevent many problems that might occur in a processing centre.

Where do extraction units need to be implemented
The trade association can provide precise information about which emissions require extraction during operations. It is generally preferred that too much is extracted, rather than too little. Who knows how toxic the gases during plasma cutting are, or how dangerous the grinding of galvanised metals is? These are areas where health risks can quickly develop, if one does not use an extraction unit simply because of ignorance or trying to save money. Generally, extraction units should be implemented everywhere where there is the potential of dangerous emissions. These are not necessary always in gas form. Dust from grinding or aerosols can also cause the accumulation of suspended particles in the air, which can then be breathed in by workers. An extraction unit prevents the suspended particles from setting.
Tunnel drying for good results
An industrial facility also has to be supplied with air. This is particularly useful for processes, in which air is used to some extent. In the manufacturing sector this is generally a pneumatic machine. Before the air is compressed, it needs to be dried. A tunnel dryer is used so that the air does not become humid during transport. This is particularly useful in the food industry. Drying units used for humid products are also identified as a type of tunnel dryer. These are made out of a wide and long conveyor belt, which is enclosed and equipped with heaters. The laying out of humid products is done during the transportation of the drying process. At the end of the process, the dried products fall into a container. The air emitted from tunnel dryers also needs to be extracted. This is particularly important for products containing solvents.
Composition of a ventilation duct
An extraction system contains many components. A stationary or mobile extraction unit is operated by a ventilator, which is creates a vacuum in the extraction unit. As a result, any air in the vicinity of the suction nozzle is sucked in. This is particularly notable in welding operations. Mobile or movable suction nozzles on a stationary unit are always in the close vicinity of the welding operation. The extracted air is cooled down and drawn through a filter. The type of filter required depends on the type of emission. Qualified specialists are necessary for the maintenance of the ventilation duct. The filter of an extraction unit need to be regularly changed and this change needs to be recorded.
