- **Product Or System:** PUMA 15P
- **Setup Or Configuration:** CASE STUDY ATEX Centralized Vacuum Systems for Grain Mills and Flour Keeping an industrial grain mill clean is critical. Flour dust is highly combustible, and any accumulation on floors, structures, or equipment increases the risk of explosion and fire. At the same time, grain and flour residues affect hygiene, attract pests, and can compromise product quality and brand reputation. To mitigate these risks, grain mills need ATEX-certified equipment designed for potentially explosive atmospheres, along with a cleaning system that can reach every corner of the facility—from silo floors to production lines across multiple levels. This case study describes how Depureco engineered an ATEX-certified centralized vacuum system for a five-floor grain mill in Poland , using a PUMA 15 ATEX central vacuum unit, dual pipelines, and an explosion isolation flap to keep the entire building clean and safe
- **Observed Result:** Documents a five-floor grain-mill central system using an ATEX PUMA unit, dual pipelines and explosion-isolation features.
- **Claim Boundary:** ATEX configuration and protection design must match the actual Zone, material and installation documentation.
