Tunnel Scrubber Systems

High-Efficiency Tunnel Scrubbers for Industrial Dust, Overspray & Particulate Control

Envirosystems Tunnel Scrubbers are engineered for industrial facilities requiring high-performance particulate removal inside processing tunnels, conveyor lines, roadway tunnels, and high-throughput manufacturing environments. Our systems capture airborne dust, overspray, and fine particulates keeping the environment underground clean and safe. 

Envirosystems has designed several TBM scrubbers for specific projects, and would welcome an opportunity to talk to you about yours.

A tunnel scrubber is a continuous-flow filtration system installed above or alongside a production tunnel or conveyor zone.
Its job is to:

• Capture airborne dust and overspray

• Prevent contamination inside production pathways

• Maintain clean airflow throughout the tunnel

• Recirculate filtered air back into the facility

Envirosystems scrubbers use multi-stage filtration, including MERV 15–18 high-efficiency filters, depending on your application.

Every tunnel operates differently — airflow, load, and particulate vary by application.
Our engineers design each system to match your process.
