MAFAC VAP: Cleaning Industrial Components – dynamic and highly efficient with Pressure-Change
Tight capillary structures, tortuous channels, deep threaded holes with small cross-sections? A tube more than a meter long with an inner diameter of just a few millimeters? Added to this increased, industry-specific requirements, such as residue-free cleaning of medical devices in validated, reproducible processes? This is exactly why we developed MAFAC Vacuum Activated Purification – or VAP for short.
VAP works through specific patterns of negative and positive pressure change in the cleaning bath, thus creating currents that reach and wash through even the narrowest channels. Instead of chemical solvents, only surfactant-based solvents are used. Protecting environment and human health makes MAFAC VAP particularly suitable for sensitive applications – for example in additive manufacturing, optics, electrical engineering, the laser industry, medical technology, pharmaceuticals, and food.
The innovative, patented process works in conjunction with our equally patented technology of rotating the basket and spray system. The basis for highly efficient cleaning is improved media exchange and, as a result, optimized dirt removal. To achieve this, MAFAC VAP uses a sequence of precisely dosed negative pressure. The constant change in pressure creates flow, allowing the cleaning medium to penetrate even the narrowest blind holes. Filmic and particulate contaminants are removed mechanically in a material-friendly manner; even the finest particles are reliably eliminated from the process.
If you have ever tried to clean a long, thin drinking straw, you know the problem on a small scale: The inner contours never get hygienically clean, either under the tap or in the dishwasher. This made the cleaning tests we set up for evaluating the performance of MAFAC VAP even more challenging:
Can a 1.2 meter long, fine hose with an inner diameter of just 4 mm be cleaned without any residues left? The striking result, visibly confirmed by a contrast agent: Yes, thanks to the asymmetric flow effect the medium in the tube is completely replaced!
