1977 - Gerd Kemper founded KEMPER GmbH
 
The danger of the eyes suffering from conjunctivitis during welding is well known. However, welding fumes were not considered harmful to health. At that time, no one was yet considering statutory limit values, just as no one was considering effective extraction technology.
 
In Sweden, Gerd Kemper discovered his first extraction units after his business vocational training period at a company with a technical background. There, the hazards caused by welding fumes were actually known - even if this was rudimentary compared with today's knowledge.
 
Gerd Kemper brought this knowledge back to Germany. In the garage at his home, he constructed the first spot extraction system in the German-speaking countries - a filter unit which collected and extracted the welding fumes directly where they were created.
 
To this day this principle of welding fume extraction is being recommended by the employers liability insurance associations.  The company is still considered to be a pioneer in welding fume extraction.

1983 - First production building in Vreden

 
Thanks to the success of the company products, KEMPER grew in both contract volume and number of employees - the company had 10 employees by as early as 1979. The capacities were too small at the old location.
Six years after its founding, KEMPER expanded to a major extent for the first time. The manufacturer invested in a new location.
The company set up its first production building covering 3600 square metres.
This provided more space for an extended range. In addition to welding fume extraction, KEMPER started producing extraction solutions for cutting applications using thermal cutting tables.
 

These videos show Kemper Extractors on site and in the working environment.  Often you will find Kemper in use with gas and plasma profile cutting systems, extracting cutting fumes.

The display for the filter monitor and the connecting plug for the clamp of the optional automatic start-stop is also located there.
The filter unit filters the polluted air according to the principle of electrical charging. A preliminary filter cleans the polluted air from coarse particles, before they will be charged by the ionisation wire of the filter cell and deposit on the charged collector plates. The filter cell can be taken out for cleaning.
 

KEMPER Cartridge Filter Unit with Flexible Exhaust Arm
Stationary welding smoke extraction units with two KemTex® ePTFE filter cartridges are developed for industrial use. Due to self-cleaning filter cartridges it is suitable for the frequent use at heavy duty applications. It can be mounted to the wall, a column or a free-standing pillar.
The filter cartridges work according to the principle of surface filtration, the captured dust particles cannot penetrate the filter media. This is achieved by an KemTex® ePTFE membrane which is laminated onto the actual cartridge filter material.
The unique microstructure of the KemTex® ePTFE-membrane consists of millions of fine fibres, which hold back even the smallest particles. Especially during the welding and cutting process superfine particles are generated, which are averaged between 0,1 µm and 1,0 µm. They are therefore alveole exchangeable. Especially those particles deposit on the alveole (pulmonary alveoli), reach the bloodstream, could diffuse through the vascular wall and then deposit in the body.
The filter status, as well as all the other functions will be controlled by the integrated control. Reaching a certain limit value, the filter cartridges will gently be cleaned one after another and the collected dust can easily be disposed by the dust collecting bin. The stationary cartridge filter could directly be equipped with a flexible exhaust or a rigid metal tube arm with a length of 2 m, 3 m and 4 m or by means of a console with 5 m, 6 m and 7 m long arms.

KEMPER Dusty - Mobile High Vacuum Fume & Dust Extraction Unit
Ultra light, flexible and powerful.
These are only some properties of this small power pack. Two strong turbines provide an excellent extraction efficiency and high static pressing. The minimum weight makes it very flexible and universal for many different applications.
A KemTex® ePTFE membrane filter cartridge provides the filtration of superfine dust below 0.1 µm. Thereby this unit is suitable for the separation of alveole exchangeable dusts. The advantage of surface filtration is that the filter cartridge can be cleaned.
In case of the Dusty, this happens manually in that minute when an essential cleaning will be indicated by the instrument itself. The collected dust can be removed easily from the lower part of the unit.
