During industrial operations like welding or soldering, fumes and particles are produced. These particulates can pollute the air of the workplace, posing health and safety hazards which can ultimately lead to potential damage to the human body and production equipment. This is why the fume extraction system has become an integral part of industrial processes wherein fumes, smoke, odor and other chemical particles are produced.
Fume extraction systems of any kind have one common goal – to perform fume welding extraction and dust extraction where harmful particulates produced during welding processes are removed. They are the ideal and logical solution for harmful fumes in an interior setting. But how exactly does the system work? We’ll address this in the rest of this article.
The fume extraction system basically involves the use of a fume extractor – a device that uses a fan to draw fumes and dust particles into contained filtration system. Such a system is almost always under close regulation by laws.
The filtration system of a fume extractor is responsible for performing dust extraction and welding fume extraction. Welding fume created from industrial processes such as welding, grinding, and spraying is removed from the air surrounding the workplace, protecting workers from inhaling harmful particles which can cause adverse damage to the respiratory system.
In a fume extraction system, a high-quality fan also complements the filtration system. The combination of both is able to generate a circulating air flow for ductless unit, efficiently extracting welding fumes. Fortunately, these units do not occupy too much shop space, and can in fact be installed on various locations, such as on the bench top, wall, floor, etc. No matter how these extractors are deployed, they’ll do a good job undertaking welding fume extraction and dust extraction.
Fume extraction systems can be classified into several types:
● Portable: As the name suggests, a portable fume extraction system is compact and lightweight. It can be easily transported thanks to the heavy duty wheels mounted at the bottom. This type of fume extractor is ideal when you need to have an extractor carried one from one site to the other, enabling optimal adaptability to operation changes.
● Benchtop: This type of fume extraction system is almost always sitting close to the designated operation, mounted right where it is needed. These units have small footprints to occupy little space on work table. Benchtop fume extractors are phenomenal for soldering operation, pharmaceutical sorting or other relatively smaller scaled projects that could create fumes.
● Wall Mounted: A wall mounted fume extraction system is known for space-saving as it is mounted on the wall. It is generally equipped with an extended arm hose for capturing fumes, which can either come self-supporting or be manually moved by the operator. Some of the corresponding applications include soldering fume extraction, brazing, welding fume extraction, organic vapors, chemical fume extraction, light grinding and various other industrial processes where the wall-mounting mechanism is suited.
● Stand Mounted: Stand mounted fume extraction system is another decent alternative when the option of wall mounting is not available. This type of fume extractor is ideal for oversized machinery or when the user wants to conserve floor space. Some of the relative applications include welding fume, laser fume extraction, chemical fume extraction, pharmaceutical powders, printing fume extraction, soldering fume extraction, light grinding, particulate control, and a wide myriad of other industrial processes involving relatively larger scale projects.
Choosing an extractor for welding fume extraction is not as hard as you think, and largely depends on your operation requirement. The first thing to consider is to determine what kind of particle you are looking to remove, whether it is the common welding fume or gas, or the inflammable type of fumes.
Next, you need to decide whether you need your fume extraction system to be stationary or portable. For operations that require a high level of flexibility, you’ll be better off with a portable fume extraction system. For shops with limited space, a stationary unit is perhaps the better choice.
Lastly, you need to account for the frequency of your welding operation. For shops that undertake welding on an occasional basis, you may only need a lightweight unit. For operations that place emphasis on environmental cleanliness and sustainability, you may opt for a self-cleaning unit. For operations that are undertaken on a frequent basis at a predefined location, a stationary unit may be better to ensure proximity.
Other factors you can consider when choosing a fume extractor system includes:
● How many welders do you have available?
● Is a robotic welder involved?
● How big is your facility or workshop?
● Where does your metalworking operation take place?
● How often does your metalworking operation take place?
● What is the available floor space?
Answering the above questions will further aid you in determining the most suited extractor for your workshop.
