Compact Mobile Dust Collection Units
ATEX-Compliant Mobile Dust Collection Systems with Cartridge Filters and Pulse-Jet Cleaning
Compact Mobile Dust Collection Units, are cartridge-filtered, modular and portable dust collection systems used to safely filter dry dust, fumes and particles generated in industrial processes close to their source.
It delivers high-efficiency filtration for combustible-dust applications with ATEX risks, chemical processes, food production, pharmaceutical processes, sandblasting, epoxy coating, carbon, aluminium, zinc and bulk powder transfer applications.
1,000–16,000 m³/h Airflow
It can be adapted to low- and medium-capacity mobile dust collection applications for different process points.
ATEX Ex II 3D Compatible
For applications involving combustible dust, dedicated safety solutions can be assessed according to the ATEX area classification.
Pulse-Jet Cleaning
Cartridge filters can be cleaned automatically with compressed air without stopping the system.
What Is a Compact Mobile Dust Collection Unit?
A compact mobile dust collection unit is portable, cartridge-filtered, high-efficiency equipment designed to flexibly collect dry dust and fume emissions generated at different points in industrial facilities.
The system can be designed in a compact configuration with a pre-separation chamber, cartridge filters, a Pulse-Jet cleaning mechanism, fan unit, dust collection hopper and ATEX safety equipment. It can therefore be used for both local extraction and small- to medium-scale central dust collection applications.
Key Technical Features
It can be configured for different applications within a 1,000–16,000 m³/h airflow range.
Modular filter-surface options with 2–16 cartridge filters can be implemented.
Emission levels of ≤ 5 mg/Nm³ can be targeted with appropriate filter selection.
Depending on the model and fan selection, a low noise level of approximately 68–75 dBA can be achieved.
It can be assessed with an appropriate safety approach for environments classified as Ex II 3D.
Continuous operation is supported by a reverse-flow, high-pressure Pulse-Jet cleaning system.
Technical Configuration of a Compact Mobile Dust Collection Unit
Pre-Separation Chamber
Contaminated air passes through a pre-chamber that helps separate coarse particles before reaching the filter cartridges.
Cartridge Filters
Dust particles are retained on the outer surface of the cartridge filters, while clean air is discharged from the upper section.
Pulse-Jet Cleaning
Filter elements can be cleaned by a high-pressure reverse-air pulse without interrupting operation.
Explosion Vent Panel
In the event of an explosion, a vent panel can be used to safely discharge excess pressure from the filter housing.
System Features
Compact and Mobile Design
It can be positioned close to different process points on site. Its compact housing minimizes the floor space required in production areas.
Modular Cartridge Filter Design
In standard applications, configurations with 2 to 16 cartridge filters can be adapted to different airflow and dust-load requirements.
Integrated Fan Option
A self-contained local extraction system can be installed with the compact fan-equipped design. Fan capacity should be selected according to airflow and pressure requirements.
Low Noise Level
The fan and housing design can help achieve a lower noise level in the workplace, contributing to operator comfort.
ATEX and Explosion Safety
When selecting a compact mobile dust collection unit for processes involving combustible dust, the dust’s minimum ignition energy, Kst value, St class, area zone, dust concentration and extraction-line layout must be assessed. For the official ATEX framework, see Directive 2014/34/EU.
Filtration Principle
Contaminated air first enters the pre-separation chamber, where coarse and heavy particles are separated. The airflow then passes through cartridge filters; dust particles are retained on the filter surface and clean air is discharged from the top of the unit. Dust accumulated on the filters is removed by periodic Pulse-Jet air pulses.
Applications
Key Considerations When Selecting a Compact Mobile Dust Collection Unit
Dust Characteristics
Particle size, density, moisture content, combustibility, spark risk, MIE and Kst value determine the system design.
Airflow and Fan Selection
The number of extraction hoods, duct length, filter pressure loss, air velocity and process-point requirements determine fan capacity.
ATEX Safety
The area zone, explosion venting direction, grounding, spark risk, filter type and mobile-use conditions should be assessed together.
