Get Extraction Smart
No matter what workshop you work in, extraction is paramount. Your safety should always come first and making sure you have the right extractor for your work will improve this no end.
If you’re an employer or employee, you will have undoubtedly heard of LEV (Local Exhaust Ventilation) and its implications, as in the workplace you have to comply to COSHH (Control of Substances Hazardous to Health) regulations. But if you’re a home user, you may not have heard of it.
What is LEV?
Simply put, LEV is extraction and is about getting the right system in place for the type of work you do. This is so you can reduce exposures to airborne contaminants such as dust in the workplace.
An LEV system typically comprises five parts:
- Hood – Captures the contaminant at its source
- Ducting – Conducts air from hood to discharge point
- Air cleaner – Filters or cleans extracted air
- Air mover – The engine that moves the air through the system – usually a fan
- Discharge – To release air into a safe place
We could go on and on (very easily) about this subject but we won’t as you would be here for quite a while. If you want to learn more about LEV, the HSE has an extremely thorough guide on all of its aspects which you can find here.
What we ARE going to give you is a brief insight into how you can get the right LEV system in place for your wood workshop so you can stay safe while working.
Extractors for the small home workshop
As this generally involves you, working in your own workshop, you don’t have to comply to COSHH regulations about LEV. However, this doesn’t mean that you shouldn’t think about it, far from it in fact.
When thinking about extraction at home, it’s important to consider the size of the machines, their extraction ports and the air velocity needed to safely extract the waste.
A lot of smaller machines will have extraction ports in varying sizes ranging from 31 to 63mm, so getting the correct extractor and extraction system that will maintain high air velocity in these systems is vital. We would recommend a vacuum extractor (low air volume, high vacuum pressure) to reduce the risk of blockages.
Other things to consider with this is a 63mm extraction system and rubber reducers to connect the smallest of the machines to the system itself. If you’re someone who uses a mobile vacuum extractor connected to a single machine then a 63mm hose kit will suffice.
Extractors for the large home workshop
Once again, this shouldn’t have to involve complying to COSHH regulations if it’s just you using the space, but depending on the machines you’ll be fitting this to there are a few questions to answer.
When discussing a larger home workshop, we’re talking about machines with 100mm dust extraction ports which will require high volume, low pressure extractors such as the AWEDE2, which has a 1hp motor.
If you’re connecting a single machine to the extractor, a 100mm hose kit with hose clips should suffice, as long as the extractor you’re using has an airflow higher than the machine’s minimum extraction airflow rating. These ratings will be found on the machine’s specification tag, on the website or in the product manual.
Connecting to multiple machines? A basic 100mm dust extraction kit is a great place to start using an extractor with a bit more ‘suck’. A 2hp model will generally have enough airflow to cover using a couple of machines at once.
Extractors for the trade workshop
If you’re setting up a new trade workshop or thinking of expanding to become an employer you may be interested in…
No matter what the workshop, extraction must be considered and not just any old extractor. Take time to understand the right extractor you need for your needs. Always make sure you have an extractor with comfortably enough air flow, a system that will allow air velocity to be maintained and ensure you equip yourself with products from a supplier that you trust. If you would like to know more on which extractor is best for your workshop take a look at our helpful Dust Extractor Buying Guide.
With all of these things, you can be confident you and your colleagues will be working in a safe environment so you can concentrate on the important things.
