Industrial vacuums for Valuable Powder & Precious Material recovery
In many industrial processes, residues are not waste, but resources. Recovering valuable dust and precious materials makes it possible to turn production waste into profit by reintroducing materials such as rare metals, 3D printing powders, and pharmaceutical active ingredients into the production cycle. Delfin extraction solutions guarantee accurate separation and absolute filtration, improving plant profitability and meeting modern circular economy and sustainability requirements.

The best products for vacuuming valuable dust
Delfin provides specialized solutions for the safe and efficient handling of high-value materials.
Regulations and standards for the circular economy
Recovering powders and processing residues is not only a technical choice, but a strategic decision aligned with European directives on circular economy and sustainability.
Transforming waste into value means improving process profitability, reducing waste, and building a more efficient and competitive industrial model.
Technologies to maximize recovered value
To ensure optimal recovery of production residues, Delfin adopts systems designed to preserve the quality of the recovered raw material:
Absolute Filtration for Raw Material Recovery
Multi-stage absolute filtration systems for the capturing of high-value micro-dust, with efficiency up to 99.9995% (HEPA 14) both on material collected from surfaces or process machines and airborne dust. Designed to capture every fraction, from coarse particles to the finest micropowders, ensuring complete material recovery and its reintegration into regeneration or melting processes, maximizing its recoverable economic value.
High-efficiency separation technology
Integrated solutions for the advanced separation of liquids and valuable materials, designed for the complete recovery of solids and process fluids. Multi-level filtration systems that guarantee progressive solid/liquid separation, controlled reintroduction into the production cycle, and maximization of operational efficiency, reducing waste and economic losses.
Gastight technology
With Gastight technology, powders are extracted directly from the production process and reintroduced into the same cycle, preserving their physical and chemical characteristics. The system uses an inert gas as a transport medium, preventing contact with oxygen and avoiding oxidation, degradation, or loss of raw material performance. In a closed-cycle configuration, the powder is kept intact in a controlled environment and reintroduced into the process without alteration, ensuring maximum recovery. Ideal for applications involving air-sensitive, reactive, hazardous, or high-value powders, it ensures operational safety, quality protection, and production continuity.
