SB is spark arresting device that reduces risk of fire or explosion, protecting people and objects. It’s installed before filter units to prevent fire risk up to 99%. Spark arrester prevents the coarse particles that potentially creates flammable or explosive dust.
-
TFV filter unit for smoke extraction. It’s made according to EN ISO 15012 and has cartridge with PTFE membrane. It can have two extraction arms on one filter unit. The series contains a frequency regulator. Flexible suction arm can move in all directions which allows even more efficient filtration.
-
Maestral filter unit is specially designed for dust and fume extraction during welding big and complex metal parts. Filter has pulse jet cleaning system. Polluted air from the environment is sucked in at the top of the filter where it’s cleaned and is coming back to section with two openings at side.
-
Bura unit filter is compact and mobile series ideal for use with big amounts of smoke when welding large constructions. Extraction is done on the torch which allows it to be very efficient. Filter cartridges are cleaned with Pulse Jet. Unit starts automatically when the welder starts welding, which reduces power consumption.
-
SNR series non-return valves are used to prevent the passage of an explosion in the suction line. Designed as a protection system for dust return to the production plant, helps to prevent the return of fire / explosion occurred in the filter unit in the plant. They are suitable for preventing explosions and returning back to the production hall from the filter. Safe solution for isolating the environment in the situation of an explosion.

The TFI type rotary valve is used to transfer material between two separate systems. In pneumatic conveying systems, discharge is usually required from the filter or cyclone to the silo, at atmospheric pressure. This is an ideal application for the TFI type rotary valve. The rotary valve can be used for emptying of several non-adhesive material types. Max. particle size for the TFI is 13 x 13 x 13 mm. The rotary valve should not work with highly abrasive dust.
- Robust construction.
- Long lifetime. The rotor is equipped with an elastic clutch, which reduces the possibility of damage in use and maximizes the life of the unit.
- Effective air lock between the inlet and outlet provided due to the special rubber blends.

EBR side extractor was developed for the extraction and discharge of waste material from silo. It’s made of metal construction, leaf springs and helical shafts driven by a gear motor. The leaf springs loosen the material in the silo, and the helical shaft transports the material to a rotary extractor that removes the material from the silo.
