Deapura "AS528/532" water-wet filter unit for sharpening dust extraction and filtration
Deapura AS wet dust collectors: instant spark stabilization for log saw sharpening tools across Paper Converting production lines.
The Deapura AS series is a wet filtration and stabilization system specifically engineered for extracting and neutralizing glowing sparks and metal grinding dust generated during log saw and slitter blade sharpening inside the Paper Converting industry. In tissue and cardboard manufacturing plants, the combination of hot metallic dust and fine paper fibers creates a severe flash fire hazard. Utilizing an internal AISI 304 stainless steel tank regulated by electronic safety probes, the extraction flow is drawn through a water bath that instantly quenches and settles incandescent particles, delivering high gravimetric retention and blocking duct fire propagation.
Primary water-bath scrubbing engineered to quench hot metal grinding dust and sparks.
Fire hazard mitigation across Converting layouts via immediate wet-inertization.
Automated fluid replenishment managed via electronic safety probes and a solenoid valve.
