For 40 years, we at ESTA have been helping our customers create consistently clean, healthy work environments. Our trailblazing extraction solutions for a wide range of industries have established us as a reliable premium provider. We have gained this competence through a multi-faceted commitment that includes sustained development, dialogue with users of dust extraction technology, and communication with testing laboratories and technical institutes.
ESTA’s customers include companies from a wide variety of industries and sciences, from A to Z — automotive to food, right through to zinc. The companies range in size from tiny workshops with a few employees to worldwide multinationals.
To give you an idea of our comprehensive range of services, we provide you here with examples of our domestic and international references from various industries.
Grinding pieces for large components of fibreglass-reinforced plastic produces dust. Over a distance of 50 metres, an extraction booth needs to capture these fine dusts. The customer wants the booth to be mobile and to guarantee maximum flexibility. Moreover, the extracted air must be routed back into the production hall.
The dusts are captured by a mobile extraction booth that can be moved across 50 metres to the desired position by two electrically driven dollies. The booth is equipped with lamellas on both faces. This means that only the booth needs to be moved, and not the work piece.
An energy chain rides along to provide current and compressed air. This eliminates the need for expensive reel systems.
The filter unit is mounted on a platform and moves with the booth. The system is equipped with a dust class H backup filter for extracting dust from fibreglass-reinforced plastic.
The complete unit (booth and filter system) is run from a control cabinet next to the filter system.

- Controls for the booth and extraction system
The extraction system is attached directly to the booth, which is moved on a system of tracks. The extraction system’s backup filter is for returning the air to the production hall.
At the end of 2011, a system design company in southern Germany asked us to develop a suitable workplace ventilation design to maintain the required occupational exposure limit of 3mg/m³. The production hall contains 24 workstations where structural steel is welded in single and double shifts. The purified air is to be routed back into the work area. The specific application makes it impractical to remove fumes selectively at all workstations.
ESTA installs a stationary cartridge filter system from the DUSTEX series. It uses the push-pull mix ventilation principle to extract welding fumes that arise. A pipeline system captures the fumes. It is arranged on the ceiling and equipped with 18 suction strands to cover the entire area of the hall. The purified air is routed along the two long sides of the hall at ceiling height toward the suction channel. This reduces the contaminant content in the air of the hall according to specific regulations. Permanent filter cartridges are automatically cleaned during suction and keep operating costs consistently low.
The modular construction of ESTA extraction systems allows the filter unit, fan and pipe system to be custom adjusted and dimensioned to the client’s needs. The customer was extremely happy with the installation time, which was only two weeks. The contaminant measurement equipment we installed has confirmed the workplace ventilation system’s efficiency: The contaminant concentration is far below the prescribed limit of 3mg/m.
- DUSTMAC F-567 filter unit
- MDV 75 kW
- Air intake fan MDV 11 kW
- Control cabinet 75 kW with frequency converter
- Control cabinet 11 kW with frequency converter
- Pipe system with 18 suction strands
The pipeline system is perfectly adapted to the production conditions and allows welding fumes to be captured throughout the hall.
The workplace extraction system consists of a DUSTEX modular filter unit, a fan, an air intake fan and a pipe system.
