Technical guides, case studies and industry updates for industrial vacuum systems, dust collection and material recovery.
Compare industrial vacuum filter types by material, media, and system role. This guide explains M-Class polyester, PTFE, antistatic, HEPA H13/H14, Nomex, liquid filters, Longopac collection, and filter compatibility review paths for Depureco industrial vacuum systems.
Use pH, concentration, bacteria, tramp oil, odor, chip load, sludge, and sump inspection results to estimate when a CNC coolant tank should be cleaned. This guide explains what coolant tests reveal, what they miss, how sump contamination affects part quality, and how a sump vacuum workflow helps recover usable coolant without returning it to a dirty tank.
Choosing the right sump vacuum for your CNC machine shop depends on what you are collecting, how much coolant is in each tank, and how your shop operates. This guide breaks down the key factors that affect sump vacuum sizing, coolant recovery, tank cleanout speed, and overall shop efficiency.
NFPA 660 vacuum guidance for combustible dust cleanup, including ordinary vs hazardous locations, dust collectors vs industrial vacuums, HEPA filtration, ATEX/Class II Div 2, grounding, and dust hazard analysis.
Industrial central vacuum systems provide powerful, centralized suction through fixed pipework across a facility. Learn how they work, what components they use, and why they improve safety, cleanliness, and efficiency.
Customized vacuum solutions for the extraction of straw and lime dust. Read the full case study!
Selecting a combustible dust vacuum starts with the material, pickup area and cleanup method, not horsepower alone. Use this guide to compare ordinary and classified locations, conductive-path requirements, filtration, sizing, collection and disposal before choosing a housekeeping system.
Discover how a metalworking plant upgraded air quality and worker safety with a centralized vacuum system for welding fumes. This case study covers a multi-point extraction layout powered by a Depureco PUMA FIX 10 central unit, designed to capture fumes from multiple welding stations at once.
An industrial bakery replaced manual, high-temperature oven cleaning with an automatic vacuum system built around a PUMA 15 P unit and six vacuum arms. The solution removes crumbs, baking residues, and burnt flour from multi-deck ovens between batches, reducing changeover times, improving hygiene, and protecting product quality and operator safety.
An automotive components manufacturer needed to move metal chips from multiple CNC machines to its briquetting equipment without relying on bins, forklifts, or repeated manual dumping. See how an HF high-vacuum system created an automated chip-conveying and briquetting-press feeding workflow.
An industrial grain mill in Poland installed an ATEX-certified centralized vacuum system with a Depureco PUMA 15 ATEX unit, dual pipelines, and 12 suction inlets to safely collect flour dust and grain residues across five floors, reducing explosion risk while improving hygiene, air quality, and overall plant safety.
VACUUM AND DISCHARGE SIMULTANEOUSLY ram 200 mp: the strongest ally in your cnc-shop Does cleaning your CNC coolant tanks keep slowing you down? The new RAM OIL 200 MP turns CNC sump cleaning into a fast, repeatable task. It vacuums coolant and metal chips from the tank, collects the chips in a heavy-duty metal basket, filters the cutting oil down to 150 μm, and lets you put it back into circulation instead of throwing it away. As the latest addition to Depureco’s sump vacuum range, it delivers high
