Dust extraction is a common theme especially in industrial sectors. It refers to the process of creating air which is breathable and maintaining it in a clean environment. This is done by extracting dust particles or fumes which can be created from various production process such as on construction sites, demolition works, timber sawing etc…

Why extract dust?
The purpose of dust extraction is to create a safer working environment for people by removing hazardous and non-hazardous particles from the air, limiting workplace exposure. It is a legal requirement that must be adhered to, and proper extraction must be used in workplaces where necessary. Not only is this beneficial to workforce but it can have additional benefits to lower maintenance on machinery and better productivity for businesses.

Do I need a dust extraction in my business?
Depending on the type of company you run or work in, you probably need to. Dust extraction systems come in all shapes and sizes, some large and permanent, some small and mobile. More commonly used in commercial settings, dust extraction systems remove dust and particulates from the surrounding air to make sure air is safe to breathe continuously.
What’s the difference between extraction systems and units?
Typically, larger dust extraction systems have a series of ducting hoses which collect dust at the source and move it to a collection point through filtration to be correctly disposed. Properly working systems suspend dust and particulates in the air so as not to settle on the transit route to disposal. The system expels clean air back into the surrounding environment.

Why do I need Dust Extraction Filters?
Simply, dust extraction filters remove dust and particulates from the air through a series of material filter passes. There are many kinds of filters for a range of different particulate and dust types and sizes, such as wood, paint spray, hazardous particulates and more. Typical filter types include HEPA filters, ULPA, Panel Filters etc…
What are dust extraction classes?
There are 3 dust extraction classes which are L, M & H. Each letter depicts the level of classification, L = Low, M = Medium, H = High.
L class offers a low level of ‘protection’ and are typically what you’d find in domestic vacuums. They are commonly used for low level dust extraction for particulates that are non-hazardous.

M class offers a slightly higher level of ‘protection’ than an L class. It’s typically the entry requirement for trades and on site use such as extracting concrete dust, fibreboard and other similar particulates. Although M & L class have a similar rate of suction, M class filtration is usually more efficient.
H class offers the highest rate of ‘protection’ and overall better in filtration and performance. Typically used in hazardous environments for the removal of miniscule fibres such as asbestos or for carbon filtration that can be harmful to health, they can also be used in M class environments for an added level of protection. They generally have better suction capabilities and multiple layer filtration. Guidance from the HSE is available for controlling airborne contaminants.
