Straight answers to the questions people ask most when choosing accessories for fume extraction arms.
Common accessories include on/off switches, working lights, control boxes, airflow sensors, shut-off and non-return dampers, wall brackets, extension sections, extension hoses, and rail or crane systems for extra reach.Each one solves a different problem, such as saving energy, improving visibility, balancing airflow between arms or increasing the area one arm can cover. Choose them by the problem you are trying to fix and check they are made for your type of arm.
Check the arm's model and size on its data plate, then compare it with what the accessory states it fits. Duct diameter, mounting type and electrical supply all matter, and similar-looking items are often made for different arm families.If the accessory lists compatible arms, make sure yours is on the list. If you are unsure, send our team the model details and photographs.
An automatic switch starts the fan when the arm is moved into position or when light from the weld is detected, and stops it again when the work finishes. This saves energy and noise because the fan is not running while nobody is welding.For best results, the sensor needs to be positioned and set up as the instructions describe, otherwise it may start late or stop while welding continues.
Manual switches are simple, reliable and let the user decide when to extract. They suit workstations where the arm is used continuously. Automatic systems suit shared or intermittent work where fans are easily left running.A manual system relies on people remembering to switch on, so make it habit and consider a switch fitted on the hood, where it is easy to reach.
A light is not essential, but it is a real help when preparing a weld and when working inside fixtures or under hoods, because it lights the area you are extracting from. It is common on arms used for grinding, fitting and inspection.Lights must be rated for the voltage supplied and are often low voltage with a transformer. Replace failed lamps with the specified type.
A damper is an adjustable flap in the duct. Closing it can stop air being drawn through an arm that is not in use. Some designs can also be set partly closed to help share airflow between arms on one fan.Whether this is suitable depends on the system, so follow the maker's instructions for your own arms and fan. Make sure the damper suits the duct diameter, moves freely, and that airflow at the hood is still adequate after any change.
