What your process engineer actually checks
High-volume recovery, built for AM powder
The DG 70 puts an 8.4 HP three-phase motor and 353 CFM behind a 3-inch inlet, with a large 32 ft² star filter that holds airflow under sustained load. It recovers non-reactive metal powder (stainless, nickel), heavy solids, settled dust and liquids in volume — a genuine plant workhorse. It is not an inert or ATEX unit: for reactive metals or combustible dust, we route you to a rated inert / D2 vacuum instead of overselling this one.
An applications engineer on the line
Questions on airflow, filter class, or whether the DG 70 is compliant for your alloy and volume? A named applications engineer answers directly — most replies under 4 hours, NDA standard. We run powder handling and post-processing in our own California shop.
The Delfin DG 70 is a heavy-duty three-phase industrial vacuum for picking up large quantities of solids, dust and liquids — including non-reactive metal powder in additive-manufacturing environments. An 8.4 HP three-phase motor moves 353 CFM through a 3-inch inlet, and a large 32 ft² star filter keeps that airflow steady under a sustained load. Rated IP55 and built on a heavy steel chassis, it is a high-volume workhorse for AM powder recovery, foundries, machine shops and general plant clean-down. It is not an inert or ATEX unit — for reactive metals such as aluminium and titanium, or combustible dust, use a rated inert / D2 vacuum.


Why teams choose the DG 70
What a process engineer checks before buying a high-volume unit.
8.4 HP three-phase power
A high-output three-phase motor moves 353 CFM through a 3-inch inlet — enough to recover heavy solids, settled dust and liquid in volume without stalling.
Solids, dust & liquids
One machine handles bulky solids, fine settled dust and liquid recovery, so a single unit covers mixed heavy-duty pickup across a facility.
Non-reactive metal powder recovery
Positioned for AM environments recovering non-reactive metal powder (for example stainless and nickel alloys) alongside general plant clean-down.
32 ft² filter, IP55 build
A large-surface star filter resists clogging under continuous load; IP55 ingress protection and a heavy steel chassis suit a demanding plant environment.
Match the vacuum to your material
The DG 70 is a high-volume general unit — not a rated unit for reactive or combustible material.
Non-reactive powder & heavy waste
Non-reactive metal powder (stainless, nickel), solids, settled dust and liquids in high volume across AM and industrial plants.
Reactive or combustible material
Aluminium, titanium and magnesium powder, or combustible dust, need a rated inert / ATEX vacuum — see the Mistral inert and D2 line below.
You’re unsure
Send us the alloy, particle size and volume so an engineer can confirm the DG 70 is compliant, or route you to an inert / D2 unit.
