CN-8100SM Pneumatic Stencil Cleaning System (Stainless Steel)
Electrically Safe · Ultra-Efficient – The Ultimate Pneumatic Solution for Precision SMT Stencil Cleaning
Innovation Breakthroughs
Explosion-Proof Pneumatic Drive
Powered by 100% compressed-air energy conversion, our pneumatic cleaning system eliminates electrical components – eradicating explosion/fire risks from ESD/short circuits. Ideal for hazardous environments.
Dynamic Pneumatic Cleaning Technology
32 vortex nozzles generate isobaric turbulence (0.4-0.6MPa) for uniform pneumatic aperture cleaning. Achieves 99.7% residue removal with <0.3N/mm² tension fluctuation – extending stencil life.
Closed-Loop Pneumatic Ecosystem
Patented 3-stage filtration:
- 10μm stainless mesh (solder dross)
- 5μm ceramic filter (microparticles)
- 1μm polymer membrane (flux residues)
S-shaped ducts reduce solvent use 80% with VOC emissions exceeding.
