Enhanced immersion separator with detachable tank -- runs on either water or oil, 4.5 L conductive wet bag, CFE coalescing filter of HEPA grade. Certified II 2GD to EN 17348 WT
The Tiger-Vac EXP1-10 (IT-40L) EX DT (CFE) HEPA W/3D TOOL KIT is the enhanced version of Tiger-Vac's mini immersion separator. The principle is the same: recovered powder is drawn straight into a liquid bath instead of sitting dry in a container, which Tiger-Vac describes as recovery and inertisation of combustible dust in liquid. As long as the particles stay covered they cannot form a dust cloud. Two things set this model apart from the base version. First, it runs on either water or oil, which matters for the metals that react with water -- there, oil is the only viable route. Second, it has a detachable tank (DT), so the tank can be wheeled away and swapped for an empty one without the machine standing idle. The recovery tank needs 12.3 L of liquid before use, and the conductive disposable wet bag is rated at 4.5 L. Degassing vent and liquid level indicator are as on the base model. CFE stands for Coalescing Filter Element -- a coalescing filter that strips moisture from the exhaust air and filters at HEPA grade, stated by Tiger-Vac as 99.97 % at 0.3 micron. The motor is single-phase TEFC, 1 kW (Ex d IIA T3 Gb), 224 m3/h at 1550 mmH2O. Tank in AISI 304 stainless steel. A complete static-dissipative (SD) accessory set and a dedicated 3D tool kit are included.

When the powder reacts with water. Several metals used in additive manufacturing form hydrogen on contact with water -- magnesium and, under certain conditions, fine-grained aluminium among them -- and hydrogen in a closed tank is exactly what you do not want. That is why the DT version exists: it can run with oil instead, so the bath still keeps the powder wet without a chemical reaction taking place. Which liquid is right for your particular powder depends on alloy, particle size and how the powder is stored, and it should be settled with the powder manufacturer and with Tiger-Vac before commissioning. We are happy to help get that settled.
That the machine does not have to stand idle while you empty it. The tank is released from the filter head and wheeled away on its own casters, and an empty tank goes in its place. With a fixed tank the whole machine goes out of service while the bath is emptied, the bag sealed and a new bath filled. For occasional cleaning that hardly matters. In a production line emptying daily it is the difference between a couple of minutes and a quarter of an hour of standstill. Add that a wet bath is heavier to handle than a dry container -- casters under the tank are not a luxury here.
EN 17348:2022 is the product standard for vacuums in explosive atmospheres, classifying machines by how the collected dust is handled. DT means dry type -- dry collection. WT means wet type -- wet collection, where the dust is held in a liquid. This model is WT. The classification says the machine is designed and tested specifically to keep combustible dust wet. A DT machine with the same ATEX marking is therefore not a lawful alternative for reactive metal powder. Note that the letters DT appear in two places with different meanings: in EN 17348 DT is a dust class, while in Tiger-Vac model names DT means detachable tank. This machine is called EX DT and is at the same time WT classified -- there is no contradiction.
The marking is II 2GD, that is ATEX category 2 for both gas and dust externally. The unit may be placed in Zone 1, where an explosive gas atmosphere is likely in normal operation, and in Zone 21, where the same applies to explosive dust. Ambient temperature must be between 0 °C and +40 °C. There is no separate internal Zone 0/20 marking; internal safety rests on the liquid bath. The certificate is LCIE 03 ATEX 6297.
No. The liquid in the tank is not something the machine picks up -- it is filled in beforehand and forms the bath that keeps the powder wet. The machine is a dust collector, not a wet/dry vacuum. If you need to recover liquid in an ATEX environment that is a different machine type, and we are happy to find the right one with you.
