Depureco MINIAIR 2V Z2/22
The MINIAIR 2V Z2/22 is Depureco's smallest ATEX combined vacuum without an electric motor -- 2 venturi units drive the entire suction on compressed air alone. That means no electrical ignition source in the worked area: the whole unit is ATEX-certified II 3D + II 3G and therefore allowed in rooms with Zone 22 dust and Zone 2 gas simultaneously, which is typical for refinery boundary zones, battery production and smaller process handling points. 45 L AISI 304 tank, 300 m3/h flow, 500 mbar vacuum and 73 dB(A) -- compact (550 x 620 x 1150 mm) and wheeled for a single operator. Air consumption is 2500 Nl/min at 6-8 bar -- in practice a dedicated compressor outlet, not just a factory-standard air socket. H14 absolute filter (22,000 cm2 fiberglass, EN 1822-5) is optional, not standard.

Questions and answers
Why no electric motor?
Because the MINIAIR is designed for rooms where gas may be present. An electric motor -- even ATEX-certified -- has hot surfaces and contact elements that are a potential ignition source. Venturi operation has no moving electrical parts: the compressed air itself creates the vacuum through the nozzles. That is the safest construction for Zone 2 gas.
How much compressed air does it use?
2500 Nl/min at 6-8 bar (catalogue spec A672). That is not trivial: a small factory compressor (e.g. 5.5-7.5 kW with FAD of 500-1000 Nl/min) cannot support it alone. Count on at least 15-22 kW installed compressor capacity for continuous operation, and a refrigerant-dried air supply (PDP +3°C or better) to avoid condensation in the venturi nozzles.
What is the difference between MINIAIR 2V and AC 65 Z2/22?
The MINIAIR 2V is smaller (45 L) and has 2 venturi -- it is ideal for single-operator points. The AC 65 Z2/22 has the same ATEX marking but a larger 65 L container, broader filter area (24,000 cm2) and heavier suction cycling. Choose MINIAIR if space is tight and collection volume is small; AC 65 if there are multiple operators or longer run-time per shift.
Can it run continuously?
Yes. Venturi drive has no thermal limit as long as the compressed-air supply sustains the flow. The MINIAIR 2V is designed for continuous operation and has no duty-cycle restriction. In practice it is the compressor capacity that decides whether it is sustainable over a full shift -- check the compressor FAD against the 500 Nl/min consumption.
Is H14 absolute filter an option?
Yes, H14 is optional on the MINIAIR 2V Z2/22 -- not standard. Catalogue spec: 22,000 cm2 fiberglass, EN 1822-5, 99.995 % MPPS. Depureco part number P14904 (298.00 € from the price list). It is recommended if the collected dust is a CMR category or pharmaceutical. For factory-standard HEPA, see the AC 65 Z20/21 and AC 100 Z20/21 where 28,000 cm2 H14 is included.
