When sourcing from exporters, prioritize machines with closed-loop systems to ensure solvent recovery and environmental compliance. Key features should include programmable logic controllers (PLC) for delicate material handling (silk, leather, suede), multi-stage filtration systems to prevent color bleeding, and variable speed extractors to protect high-end hardware on luxury bags. Ensure the equipment supports perchloroethylene (perc)-free solvents or hydrocarbon cleaning to meet modern eco-standards.
