Depureco ECOBULL M DEX 1/3D INERT
The ECOBULL M DEX 1/3D INERT is the 100-litre-compact INERT machine for Zone 22 reactive metal powder, where you need twice the collection capacity of the BL 45 but want to avoid the heavily installed three-phase industrial power supply. The motor is a 3D ATEX-certified side-channel blower at 1.8 kW running on ordinary 230V single-phase -- i.e. the same socket as a large domestic electric vacuum. That makes it the natural choice for smaller process rooms and pilot installations where an electrician is not available for 400V installation, but you still need to collect aluminium dust, magnesium chips or lithium powder under N2 atmosphere. The ATEX marking is II 1/3D Ex h IIIC T160°C Da/Dc -- 20 degrees higher surface temperature than BL 45 INERT, because the side-channel blower can develop higher heat, but still below MIT for the majority of industrial reactive powders. The vacuum is 180 mbar and flow is 240 m³/h -- moderate but continuous, ideal for a single collection point running for several hours.

Questions and answers
Why is it single-phase -- isn't a side-channel blower demanding?
Yes -- but Depureco has specifically chosen a 1.8 kW 230V single-phase variant here, because the ECOBULL M series is intended for small-to-medium installations without industrial electrical infrastructure. The side-channel blower at 1.8 kW draws about 8-9 A at 230V, within a 10 A group fuse at a standard European factory outlet. If you have access to 400V three-phase and need higher flow/vacuum, the ECOBULL T DEX 1/3D INERT (A1087) with 3 kW side-channel blower is the answer. Start current is slightly higher (typically 18-22 A for 50-80 ms) -- make sure your outlet is C-type fused, not B-type.
Why T160°C and not T140°C like the BL 45 INERT?
That is the fundamental difference between a brushless motor and a side-channel blower. Brushless (as in BL 45) typically keeps surface temperature below 140°C under continuous operation, while the side-channel blower motor (which is the only practical solution for 240 m³/h flow) can reach 145-158°C normally. This means the ECOBULL M INERT *must not* be used for powder with MIT below 160°C -- mostly ultrafine metal powders (nano-aluminium, certain lithium-organic compounds). Most industrial metal powders lie in the 200-400°C MIT range, so T160°C is sufficient. Check the powder SDS under "autoignition temperature".
How does it compare to the ECOBULL T DEX 1/3D INERT?
The ECOBULL T has a 3 kW motor, 400V three-phase, 230 mbar vacuum and 340 m³/h flow versus the M model's 1.8 kW / 230V single-phase / 180 mbar / 240 m³/h. Both share the same chassis, same 100 L bin, same inerting system and same cartridge filter class. Choice: take the M if your outlet is single-phase and you have a single smaller collection point (e.g. a grinding cell, a pilot room); take the T if you have 400V installation and multiple points or one very demanding process (e.g. continuous blending station). The T is about 930 € more expensive (5,550 vs 4,620 €) but delivers around 40 % more flow and 30 % more vacuum.
Can I upgrade the cartridge to an H14 absolute filter?
The cartridge primary filter is HEPA13 (99.95 % MPPS at 0.3 μm), and Depureco does not offer a direct drop-in H14 upgrade on the standard model. If you require H14-level (99.995 %), the solution is to connect an after-filter cabinet with H14 at the exhaust -- typically a 60x60 cm unit costing around 800-1,100 € as an add-on. We can help with sizing and one-click installation. The alternative is to switch to a dedicated H14 model in the FOX or PUMA series -- but those do not have an INERT container and are only a relevant alternative if you can tolerate increased oxygen percentage during collection.
How long can it run continuously?
Continuously -- the side-channel blower is S1 duty class (100 % operation) and the motor is IP55 and F-insulated. The limitation is filter pressure drop rather than the motor: over an 8-hour shift with medium-fine metal powder (about 10-30 μm), pressure drop reaches the 40 mbar limit after 6-8 hours, at which point you need to perform reverse-pulse cleaning. With very fine powder (nano-scale) it may drop to 2-3 hours -- but that also means BL 45 INERT would be a better choice (smaller bin, but better suited to fine powder). N2 consumption is continuous 8-15 Nl/min -- size your gas supply accordingly.
Which safety systems trigger automatic stop?
Three systems trigger automatic motor stop: (1) differential pressure sensor on the filter stops operation if pressure drop exceeds 50 mbar (indicating a full filter); (2) pressure switch on N2 feed stops operation if N2 pressure drops below 1.5 bar (indicating inerting is not secured); (3) over-temperature sensor in the motor housing stops at 135°C (indicating filter blockage or motor failure). In addition, the safety hydrogen vent has a passive pressure balancing that does not stop operation but passively discharges accumulated H2. All safety systems are included in the standard delivery -- nothing needs to be purchased separately.
