Stationary centralized fume extraction system CENFLOW

welding

Overview
Extract and filter harmful particles from welding fumes while reducing footprint and energy losses in the workshop. CENFLOW central high-vacuum extraction units allow simultaneous operation of multiple extraction torches and/or laminar slit nozzles. Equipped with side-channel blowers, they generate high vacuum to ensure the required minimum air velocities at 20 mm from the contact tube on each connected torch.

Benefits

• A single maintenance point
• Limited footprint
• Custom installation to fit site requirements
• Reduced operating cost via automatic motor speed regulation based on active workstations
• Eligible for the CEE grant
• Adaptable for indoor or outdoor installation

Standards Compliance

• ISO 14001

ENGMAR advice
ENGMAR high‑vacuum extraction units are a reference solution for managing fumes and dust at source. Compared with traditional workstation extraction, high‑vacuum systems extract an air volume more than ten times lower, limiting heat losses and reducing the need to compensate by introducing fresh air, which improves overall energy control.

Designed for use with extraction torches, high‑vacuum units capture pollutants as close as possible to their emission point in line with regulations that prioritize source extraction to maximize operator protection.
