Depureco PUMA 10 SP DEX 1/2D
The PUMA 10 SP DEX 1/2D is the entry point for 24/7 operation in Zone 21: 7.5 kW motor + a star filter of fully 120,000 cm2 cleaned automatically by reverse jet + TUEV panel with remote control. 750 m3/h at 270 mbar through a 100 mm inlet into a 175 L container. ATEX II 1/2D Ex htc IIIC T140°C Da/Dc (Da/Dc because of the reverse-jet pulse). H14 HEPA (110,000 cm2) included. Same footprint and electrical connection as PUMA 10 DEX (standard), but without the manual filter-cleaning routine. The choice for permanent Zone 21 installations where production can't stop for filter cleaning.

Questions and answers
Why does PUMA SP use a 120,000 cm2 star filter while FOX SP uses a 90,000 cm2 cartridge?
Different filter housings and different pulse geometry. The PUMA's larger chamber accommodates a coarsely unfolded star filter that reverse jet can pulse across the entire surface without cartridge retaining plates. This gives 33% more surface than FOX SP and is often more robust against coarse dust (star filters don't suffer the same fold-clumping as cartridges). Cartridges (FOX SP), conversely, are better for fine dust with a tendency to settle on surfaces.
What does the reverse-jet system cost in compressed-air consumption per month?
About 150-200 litres/hour at 6 bar, = about 36-48 m3/24-hour period = about 110-144 m3/month in continuous operation. Converted to compressor electricity (typically 0.1-0.15 kWh/m3): about 15-25 kWh/month. Not a large OPEX item compared to the machine's own 7.5 kW motor (roughly 1000 kWh/month), but it does require a compressed-air infrastructure.
Does the SP variant have any performance loss compared to the DEX standard?
No -- actually slightly better. Flow and vacuum are identical (750 m3/h / 270 mbar), but the star filter at 120,000 cm2 has 2.7x more surface than DEX's 45,000 cm2. That means lower effective pressure drop across the filter at the same load, which translates to more consistent suction at the nozzle throughout the shift. The performance gap widens with dust loading -- under light loading, there is no difference.
Can the PUMA 10 SP run in parallel with another unit for redundancy?
Yes -- typically with a small manifold and automatic T-valves. On primary machine fault, the secondary valve opens and suction transfers to PUMA 2. Assumes matching flow requirements. Depureco doesn't have a standard duplex kit, but an integrator can build one using PUMA models as the base. Consult us for specification.
