Air filter for road tunnels

Operation, maintenance, conservation

Operation, maintenance, conservation

FILTRONtec focusses on short downtimes, simple maintenance and low maintenance costs. This is why our air filter systems are designed for operation without constant supervision (BOB operation) - they work fully automatically and can be conveniently monitored from the tunnel operations centre.

Operations centre

The systems only have a few moving components, such as standard pumps, valves and an optional air compressor. These are maintained in accordance with the manufacturer's specifications. A maintenance manual provides precise information on:

  • Inspection intervals of the safety devices
  • Cleaning processes
  • Further maintenance work and their schedules

No specialised personnel are required to operate the filter system, which significantly reduces operating costs and effort.

The FILTRONtec gas filter consists exclusively of static components and is therefore maintenance-free - a reliable solution for continuous, safe operation.

The essential auxiliary assemblies such as pumps, tanks, control cabinet and water treatment are installed together in a technical room.
