Client News: Filtering Fume Extraction in France
EF Specialists were thrilled when one of clients in Scotland approached us to prepare a proposal for two fume extraction systems. This was for their two thermal cutting processes at their newly acquired site in France.
The first process was a Titanium booth. The booth was 32 m3, and due to the thermal cutting / arc air burning of Titanium products, an air change rate of 5 per/min was required.
We connected onto the single extract point that was provided as part of the rear mounted extract hood / plenum.
The duct was then raised vertically with a 15m run to then enter the in-line spark trap, before turning again and continuing onwards until it reaches the filter unit.
The filter unit we opted for was a Cartrijet 45CJFCD405/15×6 (cartridge / pulse jet) unit c/w 15kW (roof mounted) fan set, pulse controller, twin hopper and rotary valve outlet.
Volume and Utilisation
| Size (mm Ø) | Description | Quantity | Transport Velocity (m/s) | Airflow (m3/hr) |
| 400 | Extract Hood | 1 | 21.22 | 9,600 |
Project context:



The second process was Nickel thermal cutting application. The booth was be 32m3, and required an air change rate of 6 per/min.
We connected onto the single extract point that will be provided as part of the rear mounted extract hood / plenum.
From this point, the duct was raised vertically and broke through the roof of the cutting booth before it turns and travelled 2m before breaking through to external atmosphere.
The duct will then enter the in-line spark trap, before turning again and continuing onwards until it reaches the filter unit.
The filter unit we opted for was a Cartrijet 45CJFCD486/18×6 (cartridge / pulse jet) unit c/w 15kW (roof mounted) fan set, pulse controller, twin hopper and rotary valve outlet(s).
Volume and Utilisation
| Size (mm Ø) | Description | Quantity | Transport Velocity (m/s) | Airflow (m3/hr) |
| 400 | Extract Hood | 1 | 25.46 | 11,520 |
Upon completion of the works and a short running period, the system was commissioned to ensure the design parameters were being met from the specification.
