Wall-mounted fume extractor, a simple and effective solution

We have already covered the topic of smoke extractor in many articles, but this time we want to focus on a simple and effective solution, the wall-mounted smoke extractor with arm and integrated fan.

This protective equipment is ideal for fixed locations where welding or other professional processes are carried out that produce pollutants more or less in a radius of 4 meters from the wall, activity in a well-defined position within a production layout.

We can therefore use a fixed and not portable fume extraction system that guarantees us some strategic advantages:

• When at rest does not clutter to the ground as the fume extractor trolley
• Lightweight to use, being on the wall just a few movements to place it
• Easy to install, only requires fixing of wall bracket or column
• Guarantees a fume extraction with close collection, as indicated by the regulations
• Cost-benefit ratio really interesting

The classic application is for welding fumes suction but this solution can also be applied to suck vapors, odors, fumes provided they are not potentially explosive.

But how do you use the wall fume extractor?

As you can see from the video below just place the suction arm as close as possible to the working point and smoke protection is ensured.

Some advice for maximum efficiency:

• Work with the suction arm as close as possible to where the fumes are generated
• Reposition the arm when you notice that the fume extraction is not optimal
• Avoid working in the current of air so as not to hinder the capture speed
• Follow the modes and periodicity of cleaning and disposal of the filters indicated by the manufacturer
• Stop processing in case of malfunction of the device

Does the wall-mounted fume extractor comply with regulations?

The answer is absolutely yes, indeed respects them strictly for two reasons:
1) Close-up capture as indicated by Legislative Decree 9 April 2008, known as law 81.

2) Fumes and aspirated pollutants are expelled outside the working area; remember that it is not allowed to recirculate in the environment because the wall-mounted fume extractor in this case has no filters and because in the case of fixed systems the expulsion to the outside is always required. It will then be necessary to connect the extractor to a line of pipes.

Construction and installation

The wall-fume extractor must be installed at about 2.5/2.7 meters from the ground and has a working radius of 3 or 4mt depending on the versions. The installation is very simple and is divided into three phases:

• Fixing the shelf to the wall or column using dowels or in case the wall is not very solid by adding a back plate
• Electrical connection to the fan motor, to be carried out with an electrical panel built according to regulations and equipped with the necessary protections
• Connection of the exhaust fan to a pipe line diameter 200mm . Galvanized steel pipes as well as PVC pipes such as construction pipes can be used.

The wall fume extractor is composed of:

– Suction arm with self-supporting structure built to last over time and ensure maximum manoeuvrability always in perfect balance and black flexible suction pipe in special PVC reinforced with steel resistant to high temperatures, easy to replace in case of maintenance. – Truncated-conical spiral hood with rectangular base, made of plastic. The screen is equipped by delimiting the suction area significantly increases its effectiveness. Complete with handle and on request adjustment damper – Sturdy, welded and painted steel shelf for fixing the suction arm and fan to the wall or column – High efficiency centrifugal fan already mounted on the shelf, directly coupled to 1.5kw single-phase electric motor 220/1/50
