Application Overview

In industrial grain mills, maintaining a clean environment is critical. Flour is highly combustible, and fine airborne particles can create a dangerous combustible dust atmosphere. Without proper dust extraction systems, facilities face serious explosion risks, operational inefficiencies and hygiene compliance challenges.

To mitigate these risks, strict safety measures must be implemented, including the use of ATEX-certified industrial vacuum systems designed for potentially explosive environments. Clean working conditions also support stringent hygiene standards and help safeguard brand reputation.

Customer

Industrial grain mill in Poland

The Challenge

The client required a safe and efficient solution to maintain a clean environment across a five-floor grain milling facility. Flour dust and grain residue accumulated throughout production areas, increasing explosion risk and impacting air quality.

Why Cleanliness in a Grain Mill Matters

• Significant reduction in combustible dust explosion risk
• Improved production efficiency by preventing contamination and pest attraction
• Reduced risk of equipment malfunctions and unplanned downtime
• Higher final product quality due to lower environmental contamination
• Improved air quality and reduced respiratory risks for workers

The Solution: Centralised ATEX Vacuum Cleaning System

The client opted for a centralised ATEX vacuum cleaning system capable of collecting flour and grain dust directly from floors and processing areas into a secure vacuum container. The objective was to ensure continuous, safe maintenance across all 5 floors of the facility.

System Configuration

• Two main pipeline runs, one serving each side of the building
• One suction inlet installed on every floor per pipeline (10 total suction inlets)
• Two additional suction inlets on the first and fifth floors for auxiliary rooms
• Optimised piping layout to minimise footprint while covering the entire silo and milling areas
• Integrated explosion isolation flap to prevent flame propagation through pipework in the event of an explosion

The ATEX-certified vacuum unit collects flour and grain dust directly into the containment vessel, ensuring a clean and compliant working environment.

Vacuum Unit: SV1-836-MBA15-Z21

The central vacuum system is powered by the ATEX-certified SV1-836-MBA15-Z21 industrial vacuum unit, engineered for combustible dust environments such as grain processing facilities.

ATEX Compliance and Safety Marking

• 1/3D ATEX marking suitable for Zone 22 environments
• Internal Zone 20 certification within the collection chamber

Core Technical Features

• ATEX-certified 11 kW side channel blower
• Large surface antistatic filtration system
• SP automatic filter cleaning system for consistent performance
• AISI 304 stainless steel collection container
• Tangential inlet with cyclone separation
• Built-in flameless vent designed to contain flame and overpressure in case of explosion
• Full antistatic accessory kit (50 mm) to eliminate ignition risk during operation

Results

By implementing a centralised ATEX vacuum system, the mill now removes dust, debris and contaminants from multiple production areas in a highly efficient and controlled manner. The installation enhances explosion protection, improves operational cleanliness and supports compliance with industrial safety standards.

The SV1-836-MBA15-Z21 system provides continuous high-performance dust extraction while integrating advanced explosion protection features essential for combustible dust environments.
