MFS modular filter system

Ideal for your capture at source extraction system

The Modular Filter System simply solves the need of cleaning the air from particles, smoke, dust, gases and smells. The modular construction means that the system is suitable for both small workspaces and larger manufacturing works. By supplementing with Nederman fans, extraction arms and control boxes, you can build up a solution for every workplace.

Typical applications are TIG and spot welding, laboratory extraction, food ingredients and odours and chemical handling.

  • Simple and quick installation – few parts
  • Easy to expand
  • Can be supplemented with fan, extraction arm and control box
  • Economical and efficient

How to install the MFS filter cartridge

MFS with Particle filter

For welding smoke, dust and large particles. A complete filter unit includes filter cartridge, console and two connections.

MFS with Micro / HEPA filter

For ultra fine and contaminating particles. A complete filter unit includes filter cartridge, console and two connections

MFS with Gas / Carbon filter

Absorbs smells, gases, smoke and organic solvents (toluene and methylethylketone). A complete filter unit includes filter cartridge, console and two connections.

General guidelines for the use of Nederman Carbon filters

We get many questions on Nederman carbon filters. The questions usually concern which chemicals can be used and which can not be used. Therefore we have made guidelines to make the work a little easier how to sell this type of products.

The guidelines concern the following filters: MFS Carbon Filter, FilterCart Carbon and the filters to 
the Bench Top products

1. The filters are mainly designed for organic solvents. 

Non organic chemicals and acids can seldom be filtered efficiently. 

2. The solvent(s) should have a molecular weight over 50. 

Lighter molecules will not be absorbed very well and the life time of the filter will be very short. Very light molecules will not be absorbed at all. The molecular weight is found on the data sheet for the chemical. 

3. The filters may not be used with toxic chemicals. 

There are two reasons for this. The extractor arms can not capture 100% of all fumes and a filter that is saturated may blow toxic chemicals in the air. This may harm the operator. Unsuitable chemicals are marked with this symbol marked with the orange "toxic symbol".

4. The solvent(s) must have a clear smell

As we depend on the smell to detect that the filter is saturated. 

5. The concentration must never be so high that there is an explosion risk. 

To high concentration will also make the filter life time very short. 

6. Life time: You can not measure pressure drop over a carbon filter to calculate the life time.

A saturated carbon filter will have the same pressure drop as a new one. The carbon can absorb 10-25% of its weight before it is saturated, so one way to determinate is to weigh the filter and compare the weight between a new and saturated filter. If you know the concentration and the air flow this can be used to estimate the filter life. 

7. When you are calculating MFS carbon filters

Always make sure that the airflow does not exceed 500 m3/h (294 cfm). Higher airflow will decrease the filtration efficiency
