ATEX certified industrial vacuums - a must for 3D printers

Some 3D printing processes can create non-conductive combustible plastic powder dust which must be safely removed once the process is complete.

The potentially explosive nature of this particulate matter means it is absolutely essential to use ATEX certified Zone 22 and Zone 21 equipment which has been proven to comply with the requirements of the Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) 2002. This includes vacuum cleaners used to clean in and around additive manufacturing machines.

In addition to its explosive properties, it is widely acknowledged that exposure to polymer dust can be harmful to human health if breathed in or ingested. This type of dust therefore needs to be controlled under COSHH (Control of Substances Hazardous to Health) Regulations 2002. Type H vacuum cleaners are specifically designed for the safe collection and disposal of hazardous dusts.

Brian Folland, industrial vacuum specialist for Kerstar, said: “Type H vacuums safely collect hazardous dusts thanks to three stages of filtration. This includes a sealable, disposable microfibre bag, a High Efficiency Filter Assembly using a filter medium that is specially designed as a pre-filter material for HEPA filters, and finally a H14 HEPA cartridge filter that achieves a filtration efficiency of 99.995%.

“This keeps the potentially dangerous substance contained and ensures it can be easily disposed of – minimising exposure to the user and returning clean air to the environment.

“In addition to ensuring compliance with Health & Safety regulations, using a Type H vacuum cleaner can also provide a variety of other benefits including less time spent cleaning in and around 3D printing machines.”

All of Kerstar’s UK manufactured ATEX vacuums are third party certified to meet ATEX requirements.
