Tiger-Vac AVSD-1&2 (IT-40L) DT CFE HEPA 2GD PNEUMATIC

The Tiger-Vac AVSD-1/2 (IT-40L) DT CFE HEPA 2GD PNEUMATIC series is a high-performance inert and ATEX-certified vacuum solution for safe recovery and neutralisation of metallic dusts compatible with either water or oil. The Enhanced Mini Immersion Separator ensures that dust is immediately submerged into a liquid bath before passing through a HEPA-grade coalescing element and a downstream HEPA H14 filter. The series is available in two variants: AVSD-1 with a single venturi and AVSD-2 with a dual venturi for maximum airflow and performance.

Liquid type, compatibility and materials

Both units operate as Water or Oil Wet Mix systems. Water is suitable for non-reactive metals such as aluminium, copper, brass, steel and nickel alloys. Oil must be used for water-reactive materials such as magnesium, lithium, zirconium and pyrophoric titanium AM powders. The correct liquid type must always be confirmed via the SDS of the recovered material.

Technical construction and filtration

The models are fully pneumatic, with no electrical components, as documented in ATEX file LCIE 16 AR 077 :contentReference[oaicite:2]{index=2}. Dust is neutralised in the IT-40L immersion bath before passing through a HEPA-grade coalescing filter and a downstream HEPA H14 filter. The system includes a degassing vent, liquid level indicator, stainless steel recovery tank (SS304) and a conductive wet recovery bag. AVSD-2 features a dual venturi system, providing the highest airflow in the Mini Enhanced range.

Safety features

The AVSD models are certified II 2GD (Ex h IIC T6 Gb / Ex h IIIC T85°C Db) and comply with EN 17348 for combustible and self-heating dust collection :contentReference[oaicite:3]{index=3}. Proper inertisation requires correct liquid level, correct choice of water or oil, full bonding/grounding and the use of static-dissipative accessories. Only metallic dust may be recovered. Organic dust is strictly prohibited.

Industries

Metal additive manufacturing, powder metallurgy, machining, ammunition handling, laboratories, electronics, energy sector and all production settings requiring pneumatic ATEX-safe systems.

Choosing the right model

AVSD-1: Single venturi – balanced performance, lower air consumption, ideal for standard inertisation tasks.
AVSD-2: Dual venturi – highest airflow, best suited for large metal 3D printers and heavy-duty continuous operation.

FAQ

• What is the difference between AVSD-1 and AVSD-2? AVSD-1 uses a single venturi; AVSD-2 uses a dual venturi for almost double the airflow.
• Can both units use water and oil? Yes, the system fully supports Water or Oil Wet Mix.
• Can organic dust be recovered? No, strictly metallic dust only.
• Which zones are they certified for? ATEX 2GD – Zones 1, 2, 21 and 22.
• Can they run continuously? Yes, the pneumatic design allows continuous duty without overheating.
