Stationary Cartridge Filters – High efficiency filtration
Stationary cartridge filters are designed for continuous extraction of fine dust, welding fumes and airborne particulate from individual machines, multiple workstations or complete production areas. Their compact cartridge design provides a large filtration surface within a relatively small footprint, while automatic cleaning supports reliable operation in demanding industrial environments.

ABOUT STATIONARY CARTRIDGE FILTERS
What are stationary cartridge filters and when should you use them?
Stationary cartridge filters use pleated filter cartridges to capture fine airborne particulate from industrial extraction systems. The pleated design provides a large filtration surface in a compact volume, making cartridge filters particularly suitable for welding fumes, cutting dust, fine process dust and other applications where high filtration capacity is required without an excessively large filter housing. Depending on the model, Tehno Filter systems can serve individual extraction arms, several production machines or entire production areas.
Why choose cartridge filtration?
Cartridge filters are especially useful for fine and relatively dry particulate. Cleanable media reduce the need for frequent cartridge replacement, while pulse-jet cleaning removes accumulated dust from the filter surface and helps maintain stable airflow during operation. For larger systems, modular filter construction makes it possible to scale the filtration surface according to the dust load and required airflow.

PRODUCT
Stationary cartridge filters in our range
Five product families cover everything from compact workstation extraction to high-capacity central systems and room-air filtration.
CENTRAL CARTRIDGE FILTER
TFK
TFK is a stationary cartridge filter developed for welding fumes and dust generated during plasma and laser cutting, as well as other dry industrial dust applications. A pre-separation chamber removes coarse particles before they reach the cartridges, while the integrated fan is positioned at the top of the unit to provide strong extraction performance in a compact configuration.
2,200–12,500 m³/h · pulse-jet cleaning · central extraction
HIGH-CAPACITY MODULAR CARTRIDGE FILTER
MFK
MFK-HD is a modular cartridge filter designed for demanding industrial processes and extraction from multiple workstations. Its large cartridge filtration area, pulse-jet cleaning system and modular construction make it suitable for medium-pressure systems and applications where filtration capacity needs to grow with production requirements.
Up to 44,500 m³/h · up to 690 m² · modular design
ROOM-AIR FILTRATION SYSTEM
MAESTRAL
Maestral is designed for welding halls and production areas where direct extraction at every source is difficult or insufficient. Contaminated room air is drawn into the top of the unit, filtered through cartridge media and returned to the workspace through side outlets. The system uses pulse-jet cartridge cleaning and can be combined with air monitoring and frequency-controlled airflow regulation.
6,500–20,000 m³/h · room-air filtration · welding applications
WORKSHOP AIR FILTRATION
Teh-Jet
Teh-Jet is designed for workshops where local extraction is not possible or where production conditions change frequently. It can supplement source extraction in areas with large workpieces, moving fume sources or widely separated working positions. Cleanable cartridges, variable-frequency airflow regulation and pulse-jet cleaning support continuous industrial use.
8,000–18,000 m³/h · flexible workshop filtration
COMPACT STATIONARY FUME FILTER
TFV
TFV is a compact stationary filter unit designed primarily for smoke and welding fume extraction. It uses a cartridge with a PTFE membrane and can support up to two extraction arms on one filter unit. The range also includes frequency-controlled airflow regulation, while optional pulse-jet cleaning is available. Tehno Filter states that TFV is manufactured according to EN ISO 15012.
1,500–3,000 m³/h · PTFE cartridge · up to 2 extraction arms
