Depureco FOX 7,5 SP DEX 1/3D
The Depureco FOX 7,5 SP DEX 1/3D is the FOX chassis with internal cyclone and 1/3D certification. Three-phase 5.5 kW side-channel blower, 100 L container, 80 mm tangential inlet and 550 m3/h airflow at 240 mbar vacuum with automatic reverse jet cleaning. ATEX II 1/3D Ex htc IIIC T140°C Da/Dc. The cyclone pre-separation catches heavy fractions before the filter -- especially important for organic fibres, paper, granulates and coarse fillers. IP65 chassis. Suited to medium-sized industrial dust collection in Zone 22 with an internal Zone 20 requirement.

Questions and answers
What is the FOX range's main feature compared to ECOBULL and PUMA?
Internal cyclone pre-separation. The cyclone catches heavy fractions (granulate, chips, sand, coarse filler) before the airstream reaches the filter. This extends filter life significantly and lets the filter focus on finer dust. FOX is therefore ideal for dust with mixed grain sizes -- paper, fibres, granulate, wood dust, while PUMA without cyclone is better for pure fine-dust collection.
What is the difference between FOX DEX and FOX SP DEX?
The DEX variant (FOX 7,5 DEX 1/3D) has a star filter 24,000 cm2 with manual cleaning -- longer filter life, lower cost, but requires periodic operator intervention. The SP variant (FOX 7,5 SP DEX 1/3D) has a cartridge filter 90,000 cm2 with automatic reverse jet cleaning -- for continuous operation without operator intervention, larger capacity but higher cost and taller machine.
How much airflow does the FOX 7,5 SP DEX 1/3D deliver (5.5 kW)?
The FOX 7,5 SP DEX 1/3D delivers 550 m3/h at 240 mbar vacuum. Sufficient for one to two simultaneous 80 mm collection points with 3-5 m hose. Longer hoses or finer dust require higher vacuum -- choose a larger FOX variant or a PUMA in that case.
How large is the container and how is it emptied?
100 L AISI 304 container, below-machine detachment principle -- rolled out on wheels for emptying. The container catches both cyclone-pre-separated coarse fraction (upper part) and filter-cleaned fine dust (lower part). Grounding ensured via chassis bonding.
Is the FOX 7,5 SP DEX 1/3D mobile or stationary?
Semi-mobile: 177 kg with wheels, but the size (660 x 1200 x 1860 mm) makes it suited to fixed installation at a production line. Can be moved manually between service areas, but not for daily relocation. For mobility choose the ECOBULL range (95 kg) or the BL range (38-45 kg).
What does T140°C mean on the ATEX label?
T140°C is the maximum surface temperature the machine can reach during operation. The dust being collected must have an ignition temperature higher than 140°C (typically 2/3 of the ignition temperature for dust cloud, 3/4 for dust layer). The FOX DEX range covers most industrial dust types except highly ignitable metals like titanium/zirconium -- those require the INERT variant.
