ESTA DUSTOMAT Hydro wet separator
The ESTA DUSTOMAT Hydro wet separator is a pioneering solution for metalworkers who primarily carry out grinding, brushing or polishing processes involving intense spark formation in their everyday production. The system safely binds many types of metallic dust in water, reduces the risk of dust explosions and impresses with its robust construction and energy-efficient filter technology. Compared to similar wet separators on the market, this system scores points with its variable filter equipment and overall high efficiency.
Innovative wet separation technology
This wet filter works with a patented water vortex chamber in which sparks and dust are captured and cooled in a controlled manner right from the start. This effectively minimises the risk of fires and protects subsequent filter stages. The modular design is also available with several convenient equipment options, allowing users to put together the optimal configuration for their application.
To provide a brief overview, here are the most important technical features in condensed form:
- High efficiency of up to 98.7% already in the first separation stage
- Up to 4 individually combinable filters, including optional HEPA H 14
- ATEX version for the safe extraction of explosive dusts
- Compact, powder-coated steel construction for harsh operating environments
- Low sound pressure level between 73.4 and 76.1 dBA
- Easy-to-empty dust slurry and quick water change
- Powerful motors from 3.0 kW to 15 kW The wet separator unit can be operated in various performance categories and is designed for mains voltages of 400 V and 50 Hz. This means that the individual models cover volume flows of up to 10,000 m³/h, with a maximum negative pressure of 4,800 Pa. This is advantageous even in large production halls or when several extraction points are in use at the same time. Thanks to the integrated 3/4'' water connection, filling is straightforward, while a 2'' water drain allows the liquid loaded with dust particles to be emptied quickly. With water capacities between 153 and 515 litres, the various models adapt very well to different production volumes.
Dimensions vary from 850 x 1100 x 2580 mm to 1350 x 1550 x 3400 mm, with the compact design facilitating installation next to processing machines. In terms of safety features, the extraction system is manufactured in accordance with current guidelines and is available in an ATEX version to ensure safe operation with particularly sensitive or potentially explosive materials. HEPA H 14 filter elements are also available, which filter out fine dust particles with a separation efficiency of up to 99.995%.
Application examples
- Grinding and polishing aluminium or titanium components: Conventional filters quickly become overloaded due to the flying sparks, whereas with a wet separator, all particles are bound directly in the water.
- Brushing and deburring stainless steel components: Even with stubborn surfaces, there is hardly any dust pollution in the ambient air.
- Milling and machining ferromagnetic materials: High suction power prevents chips from sticking or clogging in critical areas, which minimises production downtime.
- Welding of high-alloy steels: Hazardous fumes and aerosols can be effectively directed into the wet filter so that even fine particles cannot escape.
The possible applications also extend to many other industrial processes in which combustible or hazardous dusts occur.
FAQ
How complex is maintenance?
The system is easy to clean thanks to an integrated drain tap for water and dust sludge and a fill level monitor. As soon as too much residue accumulates in the system, the water is drained, refilled and the process can continue largely without disruption.
What standards and certifications apply here?
The device complies with current safety standards and is available in an ATEX version for potentially explosive working environments. On request, an additional integrated HEPA H 14 filter ensures particularly high separation efficiency, which is advantageous for companies with carcinogenic particles.
What types of dust and materials can be extracted?
Aluminium, stainless steel and titanium dust are easily bound in the water circuit. Sparks and fine particles from welding fumes or drilling chips can also be safely separated.
How powerful is the system?
Depending on the model selected, the motor power ranges from 3.0 kW to 15 kW. This enables the wet separator to handle a wide range of volume flows up to 10,000 m³/h and generate a maximum negative pressure of 4,800 Pa.
Is the system suitable for room air recirculation?
Yes, if required by the customer, it can be equipped with the appropriate filters to return the purified air to the working environment. In particular, the low noise levels make it possible to use the system in close proximity to employees.
Conclusion
Overall, this wet separation system offers an efficient, safe and versatile solution for demanding extraction tasks in the metal industry. The specially developed water vortex technology, combined with modular filter stages, achieves high separation efficiency and reduces the risk of dust explosions caused by combustible particles. Thanks to its solid steel construction and powder coating, the unit is suitable for harsh production environments. Those who place greater emphasis on safety and environmental aspects also benefit from the optional ATEX design and HEPA filters. The system thus meets a wide range of requirements in the grinding, brushing, polishing and milling sectors and is a reliable partner for companies looking for a powerful and energy-efficient wet extraction solution.
