LFS is active in the following industries:


About us



LFS was founded September 1, 1992 with the aim of solving problems in industrial and process filtration. Started in rented facilities with a surface of 200 m2, soon this became too small and was enlarged to 600 m2. In 2009 we became master in our own house by building new production and office facilities in Klazienaveen. Started with a surface of 1000 m2 and enlarged to 1400 m2 a couple of years later. In 2017 the next door building was bought enlarging the production surface till 2400 m2.


The production includes wound filtercartridges, meltblown (polyspun) filtercartridges, pleated filterelements, PP, PE and PVDF filter housings. LFS has many possibilities for the supply of a large range of filterbags and stainless steel filter housings also in sanitary execution.
In the course of over 25 years existence a large network of dealers was set up all over Europe.

ISO 9001:2015 certified.

LFS produces:

  • Plastic filter housings for low and high flows
  • Wound filtercartridges with various core possibilities
  • Meltblown filtercartridges with and without core
  • Pleated and high flow filters

and stands for:

  • Quality
  • Fast delivery

LFS distinguishes itself from other manufacturers by making complete calculations of the influences of temperature, pressure and medium.

Advantages:

  • Suitable for many applications
  • low maintenance
  • Cheap solution in many cases
  • High chemical resistance
  • Solutions based on customer requirements

Specials

One of the strongest sides of LFS is the flexability in making filter housings entirely to customer specifications. This may be a small alteration as e.g. different positions of connections or a complete new design based on the local situation. For this we use a 3D drawing program for a better visualisation.

Projects..

A modular system for replacing elements during the process. The system has electronic controlled valves for easy operation.

A simple solution to replace a complete filter pack. The dirty pack has a weight of approx. 120 kg. To remove the pack a lift construction was developed.

A stainless steel filter housing was used as an example for a plastic housing. Stainless steel was not suitable because of the chemical properties of the medium. The housing must both withstand an overpressure of 10 bar and an absolute vacuum.

Stainless steel filter housings

Besides plastic housings LFS has an extensive program stainless steel housings. They are used in various industries such as water treatment, chemistry, pharmaceutical and food and beverage. The housing surface can have various treatments.
