Our different types of dust collection equipment
industrial dust collectors
mobile
We offer a range of powerful equipment, mobile on wheels and easy to move. These dedusting systems are ideal for positioning as close as possible to the source of pollution,efficiently vacuuming one to three production machines or meeting the needs of a mobile workstation.
Their great adaptability to your environment guarantees optimum working comfort and unrivalled efficiency. These units are designed to be directly connected to one or more extraction arms, an extraction hood or a network of ducts, to collect dust and pollutants directly at source. Our mobile dust collectors can handle air flows from 1000 to 5000 m3/h.
industrial dust collectors
fixed
We offer a range of powerful , modular dust collectors for centralized, stationary dust extraction systems. These systems are ideal for vacuuming one or more machines via a network of dust collection ducts. They enable numerous collection points to be efficiently vacuumed, and large quantities of dust to be processed through a suction collector.
Our stationary dust collectors can handle air flows from 3,000 to 100,000 m3/h.
Separated dust is discharged into a collection receptacle such as a dust drum or drawer, or through a dust discharge device such as air locks or double flap gates. These fixed industrial dust collectors can be positioned inside or outside the building. What’s more, the treated air can be exhausted to the outside and/or recycled inside the building.
small dust collectors
industrial
We offer a range of portable, lightweight, compact and silent devices, providing the ideal solution for workstation vacuuming, whether integrated into a production machine or moved manually from one workstation to another.
Generally speaking, dust is collected in a drawer when the dust collector is fitted with a declogging device, or captured by a filter medium when saturation filters are used.
OberA’s small industrial dust collectors are specially designed for continuous operation and can handle air flows from 100 to 1000 m3/h.
What is an industrial dust collector?
An industrial dust collector, also known as a dust extraction system, is a piece of equipment used to capture and remove solid particles and contaminants from the air in industrial environments. These particles can be generated during production processes, bulk material handling, grinding, cutting, pulverizing, sanding and so on. Industrial dust collectors are designed to capture these particles and prevent their dispersion in the ambient air.
How our industrial dedusting equipment works
Our industrial dust collectors work on the following principle: pollutants are extracted directly from the source by means of a collection device, a suction arm, a backsplash, a suction table or an extraction hood. Particle-laden air enters the dust collector from the side or top. The heavier particles settle in the dust collector’s hopper, while the lighter dust is stopped at the surface of the filter media.
Clean air passes through the filter media and is drawn in by the main fan of the dust collection system. This air can then be discharged into the building or exhausted to the outside. In certain cases, our dedusting systems can be equipped with a second filtration stage, notably to treat CMR dusts, or to recycle treated air.
Dust accumulated on the filter media is loosened by an automatic unclogging device, depending on the level of clogging, or manually. The separated dust is collected in a dust collection tray.
Different filtration methods are available for our dust collection systems:
There are several types of industrial dust collectors, each with its own advantages and specific applications. Here are the most commonly used:
Baghouse dust collectors
Also sometimes referred to as baghouses or bag groups, are widely used in industry for the filtration of solid particles. They consist of filter bags suspended inside a structure. Dust-laden air passes through the bags, trapping particles on the surface or inside the filter media. The bags can be cleaned periodically to remove accumulated particles. There are several ways of cleaning these bags (pulse jet cleaning); the most common is pneumatic pulse jet cleaning, in which a jet of compressed air is blown into the bags. Shaking cleaning is also used when the dust is easy to detach from the media, and brushing is also used.
Advantages
- High filtration efficiency for fine and coarse particles.
- Low ascension velocity, particularly in the case of very light and/or very low-density particles.
- Large dust collection capacity.
- Can handle high air flow rates.
Applications
- Wood and furniture industries.
- Chemical and pharmaceutical industries.
- Thermal power plants and incinerators.
- Cement and ceramics industries.
Cartridge dust collectors
They are similar to baghouses, but use cylindrical filter cartridges instead of bags. Filter cartridges have a larger filtration surface and a compact design, making them suitable for confined spaces. Cartridges are usually cleaned by blowing compressed air (pulse jet cleaning) to remove particles.
Advantages
- Compact and take up less space than baghouse dusters.
- Easy to install and maintain.
- Excellent filtration efficiency for fine particles.
Applications
- Metallurgy and foundry.
- Food industry.
- Chemical and pharmaceutical industries.
- Manufacture of electronic products.
- Fumes (welding, brazing)
Cassette dust collectors
They use filter media consisting of vertically or horizontally arranged cassettes. Each cassette is made up of a set of fine filtering lamellae in synthetic material or specialized fabric. These lamellae are pleated to provide an extended filtration surface and maximize dust capture efficiency.
Advantages
- Compact, efficient design for tight spaces.
- Easy installation and maintenance.
- High filtration efficiency.
Applications
- Suitable for industries where fine particle filtration is required, such as the chemical, pharmaceutical and food industries.
- Used to capture fine dust, smoke and small contaminants.
Pocket dusters
They use horizontally suspended filter bags arranged in rows in the dust collector. They are designed to capture larger particles and bulk materials.
Advantages
- High dust collection capacity thanks to multiple filter pockets.
- Easy to clean pockets.
- Effective for capturing coarse particles and bulk materials.
Applications
Used in the construction, mineral processing and cement industries, where larger particles need to be captured.
Wet dust collectors
They are wet industrial dust collectors using a humidification process to remove solid particles and sometimes also gaseous pollutants from the air. When contaminated air comes into contact with thewater sprayed or fogged inside the dust collector, solid particles become heavier and settle out.
Advantages
- Water eliminates the risk of fire or explosion
- No filter wear
- Ideal for filtering clogging dusts
- Cost-effective solution compared to an ATEX dust collector.
Applications
- Strong sparks
- Aluminium dust treatment
- Suction of sticky, damp and flammable dusts
Saturation filter dust collectors
They are industrial dust collectors fitted with filters with a fixed service life. The saturation filter allows dust to accumulate directly on the surface of the filter itself, until the dust layer reaches a predetermined saturation point. This means that the amount of dust accumulated reaches a level where the airflow through the filter is affected and the system needs to be serviced or replaced.
Advantages
- Economical
- Reduced maintenance
- Flexible application
Applications
- Fumes, fine, sticky or adhesive dusts in small quantities or reduced use
- All types of industry (pharmaceutical, wood, stone, food processing, metallurgy, etc.)
Cyclones
They are dust removal devices that use centrifugal force to separate particles from the air. Contaminated air enters the cyclone in a swirling motion, creating a centrifugal force that pushes particles towards the cyclone walls. The particles settle at the bottom of the cyclone, while the cleaned air is discharged at the top. Cyclones are effective for coarse and abrasive particles.
Advantages
- Low installation and maintenance costs.
- Resistant to abrasive particles.
- No filter media required.
Applications
- Mining and quarrying.
- Wood and biomass industry.
- Manufacture of plastic products.
- Industrial drying processes.
OberA industrial dust collectors are available with different types of cleaning systems
