Laboratory fume extraction arms have a proven history of successful applications for the collection of fumes, aerosols, odors, and vapors from the handling and transfer of toxic and aggressive liquid and dry chemicals in a laboratory environment. Investigative chemical and biological analytical procedures, teaching, clinical and research institutions, pharmaceutical, and biotech companies, and corporate research laboratories all employ the source capture technique. The reduced amount of exhaust air, the repositioning flexibility, and minimal space requirement make extraction arms an important accessory in these environments. In pharmaceutical settings, the high dollar value of certain compounds makes reclamation via source capture a cost-effective strategy.
Laboratory extraction arms features and options:
▪ Specially designed aerodynamic joint results in a low-pressure drop
▪ 2, 3 and 4'' diameter tubes; multiple arm lengths available
▪ Ceiling mountings in eight standard lengths, wall brackets, and flexible bench mounting
▪ Standard construction is polypropylene joints and tubes of anodized aluminum
▪ Optional designs for corrosive, explosive, and anti-static environments.
▪ Accessories include a suction nozzle, metal hood, dome hood, shovel hood, or flat-screen hood
Extraction arms are the most commonly used equipment for welding fume extraction. The correct handling is decisive with regards to effective capture of welding fumes. A high coverage rate and thus the effectiveness of occupational safety largely depend on this. We explain which standards apply for the use of extraction arms and what you have to consider during handling.
Many welders know this situation: The extraction arm of the extraction system is very stiff for welding processes using local extraction. Tracking is often cumbersome and one may tempted to quickly work on some areas without first moving the extraction arm into the right position. However, correct usage and quality are important for welding fume extraction.

▪ Highly integrated products that save time and costs, as well as providing the reliability and functionality to deliver a better performance
How do fume extractors work?
Extraction filters
Most extraction units have a variety of filters depending on their requirements. These can separate fumes and dust from the normal air particles. Sparks that may be captured (in welding processes) are filtered away from any dust via gravity filters and spark arresters.
Mobile and stationary extraction units
The units can be mobile or stationary - again depending on the requirements, and are in many cases installed with a 'plug and play' set up meaning there will be no configuration problems. Simply switch it on and point.
How to use extraction units
Once the unit is installed and switched on simply point the suction head of the extraction arm within a few feet of the fume / dust source and this will suck up the fumes which will go through the filtration process, separating the fumes and dust and releasing the clean air back into the environment. The dust will be collected in a tray which should be emptied at regular intervals to keep the unit working effectively.
Changing extraction filters
The filters the extraction unit uses have a sensor in them that will inform you when they need to be changed. Changing the filters is a process that typically needs to be done within a twelve month time frame for the equipment to maintain full capacity. This is an easy process with the instructions to change your dust and fume extractor filter being very simple to follow.
