- HEPA exhaust mandatory from zoning or environmental requirements
- Remote control at an operator panel far from the machine
- Replacement of smaller FOX units when production has scaled up
- ATEX Directive 2014/34/EU -- II 1/2D Ex htc IIIC T140°C Da/Db

- IEC 60335-2-69 (industrial vacuums)
Depureco PUMA 10 DEX 1/2D
The PUMA 10 DEX 1/2D is the PUMA family's entry into Zone 21: 7.5 kW motor drives 750 m3/h at 270 mbar through a 100 mm tangential inlet into a 175 L container. ATEX II 1/2D Ex htc IIIC T140°C Da/Db, TUEV-certified electrical panel with remote control, and -- importantly -- the H14 absolute filter (110,000 cm2) is INCLUDED as standard on the 1/2D version, whereas it's optional on the 1/3D sibling. The difference vs. FOX: larger inlet, larger container, professional electrical interface. Fits production facilities where Zone 21 is permanent classification and HEPA exhaust is a compliance requirement.

Questions and answers
What concretely does a 100 mm inlet give me compared to FOX's 80 mm?
Larger cross-section = lower air velocity at the same flow = lower pressure drop in the hose. Concretely: 750 m3/h in a 100 mm hose gives about 26 m/s velocity, while 550 m3/h in 80 mm gives 30 m/s. Lower velocity means less turbulence and pressure drop, so PUMA handles twice the hose length or three times the branches. And a 100 mm hose physically transports coarse dust up to 8-10 mm grain size without blockage -- versus about 4-5 mm on 80 mm.
What's a TUEV-certified electrical panel worth to me?
TUEV approval means the panel is independently tested to EN 60204-1 (machine safety) and the ATEX directive. Concrete benefits: emergency stop with magnetic lockout, thermal protection against motor overload, phase monitoring (stops if a phase drops), remote control with lockout, and fault logging per event. On the FOX range, the electrical panel is not TUEV-certified and lacks some of these features. Practical benefit: fewer nuisance stops and better fault diagnostics.
Why does the PUMA 10 1/2D show 270 mbar while the 1/3D has 280 mbar?
The adjustment comes from the 1/2D using a slightly different motor configuration that delivers higher flow (750 vs 700 m3/h) at the cost of some mbar. In practice, 10 mbar is under 4 percent difference -- you won't notice it in operation. The flow increase to 750 m3/h is, by contrast, noticeably advantageous with long hoses and multiple simultaneous points.
Can the remote control panel be moved to another room?
Yes. Standard cable is 5 m, but can be extended to 20 m without signal degradation (shielded cable, CAT5e or better). Good for permanent installation in a separate electrical room or operator cage. Note: the remote enclosure must be in a non-ATEX zone, or itself be ATEX-certified for the relevant zone.
Where does the PUMA 10 fit relative to the PUMA 15 or 20?
PUMA 10 is the entry point: 750 m3/h covers 3-4 pickup points, but without margin. PUMA 15 (950 m3/h, 11 kW) delivers 25% more flow and 30% more mbar -- typical choice at 5-6 points or long hose runs. PUMA 20 (950 m3/h, 15 kW) raises only vacuum (350 mbar) -- relevant for fine dust and long hoses. PUMA 25 (1350 m3/h, 18.5 kW) is volume expansion: 6-8 points simultaneously.
