Welding Fumes Extracted by Used Kemper Equipment

Today, KEMPER is a successful family business. Neither its growth nor its international focus have changed this important aspect of its identity.

KEMPER doesn't fall behind. The innovations in filter devices and extraction equipment are geared to the needs of customers and regularly exceed the specified legal requirements. This results in absolute legal certainty for occupational safety and environmental requirements for users.

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.

KEMPER Flexible Exhaust Arm 2m, 3m & 4m 
KEMPER exhaust arms are extremely suitable for extracting welding smoke, gases, damps, slight dusts and solvents. The exhaust arm consists of an interior parallelogram which is spring supported, a fibre glass hose with a PVC coating and an internal steel wire spiral. The exhaust hood with a damper is rotatable by 360° and can therefore be swivelled in all directions. Due to its interior parallelogram the exhaust arm can be brought into any desired position within its reach without any additional support.

KEMPER exhaust arms can be connected to fans or to a ducting of a central filtration system

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.

KEMPER Flexible Exhaust Arms - 5m, 6m & 7m
KEMPER exhaust arms with a length of 5 m, 6 m and 7 m are equipped with a ball-bearing swivelling wall extension boom. A standard swivelling exhaust arm with a length of 2 m, 3 m, or 4 m is fastened to this wall boom. The special way of fastening the arm to the boom allows to swivel the exhaust arm by 360°. A C-profile is fastened to the bottom of the wallboom so that equipment or a wire feed unit up to 50 kg can be fixed to the included travellers. This makes work easier, helps to protect expensive material and prevents accidents being caused by tools and cables on the floor. KEMPER exhaust arms can be connected to fans or a ducting system

KEMPER Telescopic Exhaust Arm
The telescopic arm has been designed especially for welding schools where small welding tables are in use. In these places it is difficult to use the standard exhaust arm, which would disturb the trainee with its wide swivel range.

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.
