The SFS is in accordance with the following directive:
- EMC 2014/30 EU
The SFS with T-Flex (counterweight) is a stationary unit with self-cleaning filter.
Recommended for
- Medium to medium-heavy applications
- Professional manual welding
- Intermittent semi-automatic welding
- Robotic welding
The SFS with T-Flex (counterweight) is a wall-mounted self-cleaning filter for welding fume extraction system up to 1200 m3/h. Typical uses are small extraction hoods or arms. The SFS uses the patented RoboClean for automatic cleaning of the filter.
Features
- Long filter life
- Heavy-duty external spark arrester for enhanced safety and easy maintenance
- Roboclean automatic sectionwise cleaning of the filter cartridge with compressed air
Telescopic extraction arm with counterweight
The extraction arm is based on a telescopic tube with counterweight mechanism, allowing it to be extended to give a 2,5 m (8.2 ft) working radius and compressed to 1,5 m (5 ft). The arm is fitted with a spring-balance which enables it to be moved from a vertical to a horizontal position in one easy movement. If mounted on a column, the arm can be turned through 300° due to the rotating hinge. All movement of the arm is controlled from the hood.
This popular filter unit has a fan waiting!
The SFS with T-Flex (counterweight) can be attached on the following extraction fans:
- FAN-28; Welding processes with light to medium intensity.
- FAN-42; Welding processes with medium to medium-high intensity.
A stationary filter unit alone, won't do much!
Combine the SFS with one of the following extraction arms:
- SFS with Flex
For low to standard number of position changes. Designed for all kinds of dry welding activities, like MIG/MAG, TIG, stick, electrode and spot welding.
- SFS with UltraFlex
For standard to high number of position changes. Designed for applications that generate oily welding fumes.
- SFS with UltraFlex (low ceiling)
For standard to high number of position changes and low ceilings. Designed for applications that generate oily welding fumes.
- SFS with T-Flex (telescopic arm)
Designed for standard welding applications at workbenches and in small, fixed workingplaces.
- SFS with T-Flex (counterweight)
Telescopic extraction arm. Designed for standard welding applications at workbenches and in small, fixed workingplaces. More precise positioning due to the counterweight.
