The suction arm, let’s know this fundamental tool better

1. Suction pipes, that is the pipes where the fumes and pollutants sucked in by the arm
2. Support structure, we colored it in red to make it notice, it is the most important component of a good suction arm, what makes it self-supporting, that is, it stays “suspended” in the vacuum
3. Extractor hood, the one that handles the operator to move the suction arm and the one that aerodynamically “catches” the pollutants.
4. Support bracket, depending on where and how the suction arm is installed it can be wall or column with extension or trolley

• Length, working area or radius: fundamental parameter refers to the distance to which the arm hood must reach when it is completely extended as can be seen in the image on the right. Usually the arms are produced in lengths of 2 – 3 – 4 meters. Besides it is not possible because of the supporting structure which should be too heavy.
• Diameter of the suction pipe, from the hood to the wall. In this case the most common and available on our platform is the diameter 160 mm; on request 125 and 200 mm are available.
• Type of suction pipe which can be with rigid tubes with external supporting structure or with flexible pipe with internal structure. We will cover the pros and cons in another specific article.
• Type of hood, the most widely used “historical” ones are conical truncated, such as wall suction arm, others are rectangular and are made of composite or plastic, such as Superflex suction arm™ a new generation product.

• from the wall or column, as in the case of the Superflex arm™, in this case available without extractor to be connected to a suction system with extractor and external filters, or available with integrated extractor on the bracket, in order to have maximum production flexibility and to be able to operate every single suction on arm
• from trolley or mounted on mobile purifier, as in the case of the fume aspirator as shown in the image on the right, normally with a working radius of 3 meters and with rigid or flexible piping Superflex™ depending on the type of dust fumes aspirated.
