The role of effective ventilation

SUB’ROCA offers ventilation solutions adapted to the specific requirements of your worksite, whether for renovation work in confined spaces or excavation work in underground tunnels or mines. Axial propeller fans are used for main and auxiliary ventilation applications in mines and underground works in order to:

• Renew the air in the environment to maintain a sufficient oxygen concentration;
• Dilute VOCs and hazardous, harmful or explosive substances in compliance with Occupational Exposure Limit Values (OELVs);
• Remove heat to maintain an acceptable temperature.

The ventilation study carried out beforehand makes it possible to define the appropriate equipment to achieve optimal energy consumption. It also determines the least restrictive ventilation network to implement for your teams.
A ventilation system is a device designed either to supply air to the excavation areas of a worksite or to extract contaminated air for subsequent treatment. It generally consists of:

• a fan;
• a duct network;
• a control and monitoring cabinet;
• a dust filtration system;
• a flow measurement device.

This system must first be properly sized to ensure compliance of the installation throughout the entire duration of the project. Our engineering department sizes your ventilation system for you.
