What is a mobile suction unit?

A mobile suction unit, also known as a mobile filtration unit, mobile suction unit or mobile filtration unit, is generally a small mobile device for extracting pollutants at source and filtering them. It is generally equipped with a pick-up arm on the appliance or a tubed inlet for connecting one or more suction hoses to a machine, hood, small vacuum table or remote arms.

Mobile suction boxes are made up of a collection arm or tubed inlet, a box with several stages, saturation filters and a centrifugal fan, usually single-phase. The pedestals are fitted with castors for easy movement. The air drawn in by the collection device (arm, table, etc.) enters the box and passes through increasingly fine mechanical filtration stages, one or more molecular filtration stages (activated carbon) and finally a high-efficiency HEPA filtration stage, if required. product is hazardous and requires HEPA filtration for clean air discharge into the building.

Suction boxes are available with very low flow rates of 80-300 m3/h for fine suction at the workstation (gluing, soldering, electronic welding, meticulous grinding or sanding operations, etc.), up to flow rates of 3,000 m3/h for suction at several workstations with a single box, or for larger work surfaces to be suctioned (suction backsplashes, larger collection arms). The housings are generally fitted with a potentiometer to adjust the centrifugal fan’s intake flow to the required intake.

Mobile suction units are used to extract pollutants such as smoke, dust, gaseous pollutants, vapors, solvents, VOCs and odors. The chamber principle enables several successive filtration stages to be superimposed, treating solid pollutants (smoke, dust) of varying fineness and granulometry, as well as gases thanks to one or more activated carbon stages.

Why use a mobile suction unit?

A mobile extraction unit is generally used to capture pollutants at a workstation. The mobile filter box can be easily moved from one station to another. What’s more, if the customer doesn’t have a vacuum network nearby, it’s simpler to position a mobile vacuum box than to deploy a network of pipes from a central vacuum system. As it is often difficult todischarge the pollutant to the outside, the mobile unit captures the product where it is generated, filters it and discharges the treated air in the same area. Filtration should be carefully matched to the pollutants, and in particular HEPA H13 or H14 high-efficiency filtration should be chosen when CMR compounds are to be filtered. Most mobile filter housings can be fitted with a tubed clean air outlet if the customer wishes to discharge clean air to the outside.

What applications are covered by mobile filter boxes?

• Mobile suction units are generally used in the following applications:
• Brazing, soldering, electronic industry
• Laboratories, handling, dosing, decanting of liquid, resin or powder chemicals
• Jewelry
• Laser machine (cardboard and plastic cutting, ….)
• Additive manufacturing (3D machine, etc.)
• Gluing stations
• Parts cleaning and degreasing ;
• Restoration of works of art, vernissage
• Sanding, grinding, stripping, polishing, deburring of small parts in metal, composite materials or plastics

How to choose a mobile suction unit?

To choose the right suction unit, first validate the types of pollutants to be treated. If only dust or fumes are involved, mechanical filtration stages will suffice. If vapors, solvents or VOCs need to be treated, activated carbon filters should be used. Increasingly, processes generate both, as material heating vaporizes materials and emits pollutants in the form of fumes (solids) and gases (mostly VOCs). In this case, a combination of particulate filtration stages (mechanical filters) and molecular filtration stages (activated carbons) is required.

What’s more, if the pollutants are toxic, you’ll need to choose a suitable HEPA filter. If the equipment is to extract explosive dusts or gases, it is essential to select an ATEX device appropriate to the risks involved.

The suction flow rate is obviously a decisive factor in the choice of appliance. We can help you find out.

Operating and maintenance costs

Mobile suction units are equipped with saturation filters. Depending on the particle size of the dust and fumes to be treated, the right combination of filters must be selected.

The more efficient the filters, the higher their price. The aim is therefore to saturate the upper stages as much as possible in order to preserve the most precise filters. If possible, pre-filtration stages should be increased (e.g. G4, M6, F9… to protect HEPA H13 or H14 high-efficiency filters). The longevity of filters depends on the quantity of pollutants, the time of use and the particle size distribution of the pollutant. In some cases, a measurement is possible to select the appropriate filtration stages.
