No matter what your current manufacturing process is, if you have a problem with fumes that create a hazard for your employees then the best solution to control this is using a source capture system. So, what exactly is “Source Capture”? Source capture involves utilizing hoods and/or hoses to extract the harmful particulates at or near the generation source. This is done to prevent the contamination from migrating to other parts of the facility and putting other people/employees at risk as well. Throughout the years, source capture has proven time and time again to be the most effective means of capturing harmful fumes and welding fume extraction arms / snorkels are the most used product to accomplish this.
What Applications Are Welding Fume Extraction Arms Typically Used In?
Most applications that you’ll find welding fume extraction arms in are welding, grinding, heat removal, dust, etc. There are always new applications being discovered where extraction arms are needed. Some typical workplaces / environments include:
· Industrial Processes
· Schools, including technical, welding, automotive, etc.
· Maintenance work areas
· Powder dumping applications
· Blending applications
· Oil Mist
· Hoods that need to be moved in and out frequently
· Pharmaceutical and Food Processing Plants
What Sizes Do Extraction Arms Come in?
While the size of the welding fume extraction arm you need greatly depends on application and surface area needed to cover (as well as fan capabilities), you’ll find extractions arms that range from 3” – 8” diameter and 3’ – 14’ in length. These variety of arms will also have CFM requirements that range from 350 CFM – 1000 CFM. While extraction arms have a typical range of 3” – 8” diameter, you’ll find that the hood on these arms are typically much bigger than the arm diameter. This is so that you can have a wider source capture coverage. Most extraction arms on the market also have pivoting and bending capabilities. This especially come in handy when needing to move the arm out of the way at the end of day.
How Do I Install an Extraction Arm?
Each welding fume extraction arm varies from manufacturer to manufacturer when it comes to installation as each product is different. However, most manufacturers have options for either hanging your arm from a wall or ceiling or an option for mounting your arm in a standing position on a workbench / table. You’ll find that extraction arms are typically shipped with all of the hardware necessary for the arm; however, some arms require quite a bit of assembly before actually installing. Once the arm in mounted, you’ll need to make sure your duct work is ran from the collector or fan to your arm. Most companies will hire Mechanical Contractors for this portion of the job.
What Should I Look for When Purchasing an Extraction Arm?
When searching for a welding fume extraction arm, you must first know what your application calls for. There are applications where only certain materials can be used (such as stainless steel) and there are applications where there are extreme dangers of explosiveness where only an ATEX rated arm can be used. However, for general purposes we recommend an extraction arm that:
· Is durable, robust, and virtually maintenance free
· Is self-supporting with smooth, low-friction control
· Is flexible in all directions and simple to position
· Allows rotation of up to 350 degrees
· Comes pre-assembled and easy to install
· Equipped with an internal damper near the hood
· Smooth Tube or flexible hose outer shell.
· Can have spare parts readily shipped to you if needed.
· Is easy to work on if needed
· Can withstand high temperatures for long periods of time (metal / steel)
What Else Should I Know About Extraction Arms / Snorkels?
Even though we are just scratching the service with information on extraction arms, it might be helpful to know that there are plenty of addition accessories to go along with your welding fume extractions arm. These accessories include:
· Extensions Boom for reaching further than 14’
· Wall, Ceiling, and Floor Stanchion for mounting in remote locations
· Over-sized Hoods for larger source capture
· Light Kits
· Higher Temperature rated Hose
