Nozzles for suction extraction for different applications 

In order to determine the existing particle load on a component within the scope of technical cleanliness, full-surface liquid extraction has been state of the art for years. For components damaged by contact with liquid media, however, wet extraction is unsuitable, which is why new extraction methods were included in the revised VDA 19.1 in 2015, including, for example, air extraction by blowing off the component in a closed extraction cabinet. However, this method is not suitable for large components such as battery systems, nor is it suitable for testing directly in the process environment. 

The particle extraction system developed by CleanControlling, which is available as a mobile compact system C|PS² or as a complete system with digital control C|PS³apex, enables the suction extraction of dry adhering particles. With special nozzles for suction extraction, particles are detached from the surface, sucked off and collected or deposited directly on a suitable sample carrier (laboratory bottle, analysis filter or particle trap). 

A wide range of nozzles for suction extraction allows components of any size and shape to be inspected for particles without damage. For optimum extraction and thus reliable results of the analyses, correct handling of the nozzles is essential. For suction extraction, a distance of approx. 2-6 mm must be maintained between the suction inlet surface and the component surface to be extracted, and the nozzle inlet surface must be guided parallel to the component surface. If the distance between the component and the nozzles for suction extraction is too small, nozzle blockage can occur, which reduces the volume flow and particles are sucked out of the laboratory bottle onto the overload filter. Too great a distance between the component and the suction extraction nozzles reduces the flow velocity of the intake air stream, with the result that the cleaning effect is reduced. 

Suction extraction nozzles - models and variants

Flat nozzles are particularly suitable for flat, large-area surfaces. Due to the wide inlet area of the nozzles, larger surfaces can be vacuumed in one operation. In addition, brush strips can be attached to these nozzles for suction extraction, which also mechanically clean the surface in addition to particle extraction. The dissolved particles can then be sucked in and analyzed. 

Angle nozzles are characterized by additional brushes attached to two or three sides. They are therefore ideal for optimally vacuuming angled surfaces - e.g. of small load carriers. 

Round nozzles enable the targeted extraction of particles on small components. To achieve an optimum distance between nozzle and component, round nozzles can be connected to a plug-in brush by means of an adapter. 

Lance nozzles (round/oval) are suitable for blind holes, bores, gaps, etc. Lance nozzles with special air inlet slots at the suction opening prevent the nozzle from blocking on the component. 

ESD-capable nozzles for suction extraction

High-quality, expensive components or components manufactured only in small quantities (e.g. microelectronics, battery systems, etc.) that are to be returned to the production batch after a cleanliness inspection require additional ESD protection (Electro Static Discharge).

For these requirements, CleanControlling provides ESD-capable nozzles and brushes that ensure optimum dissipation and thus prevent electrostatic discharges during suction extraction on the component. ESD-capable nozzles for suction extraction are either made of ESD-capable material or receive an ESD coating.

Do you need suction extraction nozzles with an individual geometry that is optimally adapted to a specific component? We can manufacture the nozzle according to your specifications using 3D printing in any desired shape and color. Simply contact our team of experts - we are sure to find a neat solution!
