A metalworking dust and fume extraction system uses strategically-placed hoods connected to a network ofducts, supported by fans, to withdraw contaminants from the source. These hoods use specialised integrated nozzle attachments to provide immediate, close-proximity extraction.

The removed air then passes through specialisedfilters, which separate and capture varyingdustand fumes. The filtration system separates and cools hot sparks and metallic fragments, catching fine, solid metal fumes and shaking the dust into a collection bin. HEPA filters capture the finest, sub-micron particles, preventing them from being recirculated into the room. Lastly, depending on your system type: Ducted or Recirculating, it will discard the air outside or return it to your workspace.

Metalworking extraction systems protect your machines, the general environment and the health of your personnel by significantly improving air quality. Metalworking dust and fumes are highly flammable, meaning they harbour a severe explosion risk, which extraction systems help to eliminate. Furthermore, allowing dust to accumulate can lead to build-up on the key components of your machines and equipment, which can shorten their lifespan and lead to costly breakdowns.

Many metalworking dusts andfumes are recognised carcinogens, as they can contain toxic chemicals, including manganese, hexavalent chromium, and nickel. These compounds have the potential to cause lung cancer, occupational asthma, Chronic Obstructive Pulmonary Disease (COPD), and neurological symptoms.

Lastly, metalworking extraction systems ensure your facility complies with regulatory bodies such as HSE by meeting the requirements of theCOSHH legislation. Failing to install adequate systems (as is the legal expectation of company owners) can lead to costly legal action, fines and potential business closure.

Metalworking extraction systems must undergo a statutory, independent thorough examination and test every 14 months, and be checked daily for developing issues. Only a qualified LEV engineer can perform a Thorough Examination. However, in-house personnel can conduct daily, weekly and monthly checks. Depending on the type of contaminant your metalworking extraction system withdraws, maintenance may need to become more regular.

Routine in-house maintenance activities include:
- Visual inspections of the hoods, arms and bench surfaces to detect clear dust build-up or damage
- Checking the pressure manometer reports a normal range
- Emptying the dust bin or collection tray
- Cleaning and replacing the filtration media as needed

Extractly designs every dust and fume extraction system to comply with COSHH regulations instantly. Adherence to this legislation relies on:

- The integration of spark arrestors to automatically extinguish hot materials and prevent fire
- The selection of the correct hood type and its positioning. Adequate capture velocity for the specific contaminant
- The inclusion of a visible and audible manometer
- The implementation of the correct filters
- Ease of use for in-house personnel

Extractlyalso supplies thorough commissioning reports, user manuals and logbooks to ensure complete transparency in the design of your system and benchmark standards.
