Description
ESTA is a German manufacturing company that produces a range of extraction machines covering a wide range of applications. Their wet collectors manufactured to handle with the heavy burden of flammable dusts and are built to last, this multi-stage filtration extractor suitable for grinding, fettling, linishing, polishing and trimming applications.
Description
A feature of the NA-K series, a radial fan is employed to generate the volume flow and the negative pressure needed for extraction.
The dusty air exhausted from the processing machine is guided through a pipeline (or a suitable conductive/dissipative hose connection) to the device’s intake port. This intake port leads directly into a specially shaped whirl chamber.
The lower part of the whirl chamber intensively swirls water, wetting the high speed airflow and capturing the dust in the stream to be turned into a watery slurry. The water-bound dust sinks as sludge into the flange-mounted sludge pail.
Disposal & Maintenance
For easy disposal and maintenance, there are two drain spigots on the sludge pail.
Safety Features & Controls
If the water level is too high, these can be used to drain some of the water. The drained water must be captured with a suitable container and disposed of according to local regulations.
Additionally, there is two capacitive sensors that automatically control the water level inside the whirl chamber, making sure that there is always enough water in the device. These sensors detect the minimum and maximum water level, the device automatically fills the chamber with water through an inlet valve attached to the on-site water connection until the maximum water level has been reached.
Secondary Dust Filter
A demister is located between the fan and the whirl chamber. Separating any remaining wetted dust as the airflow is swirled up, the water droplets fall into the dust slurry at the bottom of the chamber.
All dust slurry/mud settling into a mud bucket that has been flanged to the bottom of the device.
Process of Wet Dust Extraction
Typical applications include any dust laden air-stream that may carry sparks such as from grinding and fettling operations and where the type of dusts may be governed under the ATEX regulations whereby explosive dust are generated within such operations or processes as shot blasting and machining of aluminium, magnesium or any other white metal components.
The wet dust exhaust units are renowned for their robustness, as unlike many other units, there are no moving parts filters or sprays to contend with. This allows them to maintain their original suction rates, even under the most arduous of conditions.
Additional Features
- Stainless Steel construction for all the wetting parts.
- Self contained silencer.
- Water make up box.
- 7.5kW fan and fan starter.
- Duct inlet of Ø280mm.
Application Range:
- Extraction of aluminium dust.
- Dust extraction at individual or multiple workstations of adhesive and moistly dusts, especially metallic dusts that are sparks generating.
- As central exhaust station with intercepting pipe and several extraction points Your benefits at a glance.
- High suction power for adhesive and moistly dusts Ideal solution for sparks generating applications.
- High filtration efficiency (ESTA efficiency guarantee).
- Especially recommended for grinding applications that are generating sparks.
What Makes Wet Extraction Systems Specialised?
For dust that is light, sticky or combustible, wet dust extractors are the safest and COSHH approved method for filtering. The particles of dust in these types of air are either too small, adhesive or explosive to be able to be processed in a dry dust extractor.
The extractors finely apply water to the dust for a more thorough result, the weight of the water able to separate the dust from the air.
What is Wet Dust Extraction
For light, sticky or combustible dust, wet dust extractors are the safest and COSHH approved method for filtering. By applying water to air via various types of wet dust extracting methods, the dampened dust is separated by gravity, removing it from the air.
The safety factor of wet extraction that makes it suitable for explosive dusts is by wetting the dust, the water acts as a coating between the dust and oxygen in the air, preventing the dust from potentially igniting.
