Replacement filters for ESTA SRF K-10 and K-15 W3
For your mobile ESTA SRF K-10 and K-15 W3 welding fume filters, you will find compatible alternative cartridges here. The SRF K family combines workplace extraction with cartridge filters and manual compressed-air cleaning.
Choose 20304015 with 15 m² and a PTFE coating or 20303918 with 18 m² and an ePTFE membrane. Both measure 445 × 630 mm and replace reference ESTA 01000261.
Two compatible media for the ESTA reference
Both polyester cartridges are open at the top and bottom. The membrane version supports surface collection of fine particles and their release during cleaning.
More filter area in the same cartridge size
Two different filter media and filter areas are available in the same cartridge size. The ePTFE membrane cartridge offers 18 m², while the PTFE-coated cartridge offers 15 m² with the same external dimensions. The non-stick coating helps dust detach; the microporous membrane captures fine particles at the surface. Both versions are designed for compressed-air cleaning inside the unit.
Precoat and accessories
Precoat in 400 g or 1 kg packs is available for the initial treatment of cartridge 20304015 with a PTFE coating. The disposal bag is for packaging the used filter. More replacement filters: WELDEX FE, ESTA, filter cartridges.
