Depureco DF FIX 75 Z2-22

The model is EU type-approved under ATEX directive 2014/34/EU for stationary operation in external Zone 22 (dust, low risk). 'Ex h' is the construction protection type per EN ISO 80079-36/37. 'IIIB' covers non-conductive dust (paper, fibres, grain, bag dust etc.) -- note that class IIIC (conductive metallic dust) requires separate approval. 'T140' is maximum surface temperature in operation (140 degrees C). 'Dc' is the EPL code for Zone 22.

The DF FIX uses a three-stage filter and cleaning cascade: first a pneumatic filter shaker on the primary star filter (PSC), then a secondary 4x cartridge filter section with 120,000 cm2 total filter area in antistatic polyester M class, which is cleaned automatically via reverse-jet pulsejet. The result is that differential pressure is kept stable even under high dust loads and many operating hours. Manual maintenance is limited to emptying the bin (175 L) and annual filter integrity check.

DF FIX 75 Z2-22 delivers 3,900 m3/h at 7.5 kW -- sufficient for a central system with 4-8 connection points depending on hose length and filter load. Typical pipe sizing: main pipe 200 mm, connection pipes 100-150 mm. Combined with the cyclone pre-separator (tangential inlet), the cartridge filter load is significantly reduced, extending filter life. For longer hose runs or more connection points, vacuum reserve must be calculated per plant drawing.

Both are stationary central units in Zone 22, but they solve different tasks. **DF FIX Z2-22** is designed for high airflow and lower vacuum -- suitable for large pipe diameters and airborne dust, typically extraction directly from machines or from multiple suction arms simultaneously, where air volume creates the capture effect rather than vacuum. **PUMA FIX Z22**, conversely, is a traditional central vacuum cleaner with high vacuum (260-350 mBar) and moderate airflow -- suitable for smaller pipe diameters and longer pipe runs, where resistance builds up over distance and sufficient suction must be preserved at the hose end. The choice depends on whether your plant primarily has few long pipe runs (PUMA FIX) or many short, wide extraction points requiring high air exchange (DF FIX).

Yes -- IP55 enclosure and insulation class F make it suitable for outdoor installation under a canopy or in humid production environments. Operating temperature range is -20 to +40 degrees C per catalogue. For permanent outdoor installation, the GX option (AISI 304 stainless steel filter chamber + bin) is recommended. In case of frost risk, condensate drainage must be frost-protected.

Yes. We offer both installation and commissioning of central ATEX plants and mobile solutions, and ensure that the equipment is installed correctly, documented and adjusted to your environment. Installation is carried out in collaboration with your own electrical and piping trades -- we deliver the plant, the ATEX documentation and the technical commissioning, and we verify grounding, safety valve and pipe sizing before start-up. See 'About Particulair' for our geographic coverage.

We stay around. Particulair offers service agreements on both central plants and mobile solutions, ensuring that all equipment is continuously maintained and complies with applicable requirements -- including ATEX inspection, filter replacement and annual servicing. A typical service agreement covers scheduled inspections, spare parts access and documentation maintenance. Contact us for a specific agreement tailored to your plant and duty cycle.
