What your process engineer actually checks
Locked, traceable lot chemistry
Every lot ships with a COA documenting PSD, sphericity, flow rate, apparent density, and full chemistry — and a lot number you can trace. Aerospace and medical teams reorder 4+ times without re-qualifying.
Qualified parameters, not just powder
Validated parameter sets for EOS M 290, Renishaw 500Q, SLM 280, and our own AO Metal LPBF ship with the order. Load the profile and hit density on the first build — no parameter-development burn.
A materials engineer on the line
Questions on ferrite content, flowability, recyclate ratios, or HIP response? A materials engineer answers directly — not a contact-form bot. Most replies in under 4 hours, NDA standard.
About this product
The 451 BL D2 is Delfin Industrial’s best in-class vacuum. This compact model is the perfect solution to handle dry and mobile cleaning of even combustible dust. NFPA compliant & NRTL Class II, Divsion 2 certified, this vacuum is equipped with a brushless spark-free motor (average life 15,000 hours) to prevent any sparks.
The highly efficient filter system (Class M primary filter, optional H14 HEPA filter) guarantees the total safety of vaccuming operations.
The stainless steel tank makes this vacuum corrosion resistant.
Technical Features
NRTL Certified for Class II, Divison 2 hazardous locations (Pending) Industrial Applications
- Compact and portable
- Constructed with powder coated steel
- Brushless spark-free motor (average life 15,000 hrs)
- Bonding and grounding
- Removable stainless steel collection tank

SUCTION UNIT
The motor head is equipped with a Brushless motor; the lack of carbons brushes allows the use of the machine even in explosive hazardous areas. The motor is protected by a series of filters and it is turned on by an independent switch placed on a soundproofed and robust metal motor head.
The motor head includes a vacuum gauge and tension power lights as standard.
FILTER UNIT
The large surface star antistatic filter, located inside the filter chamber, is made of polyester and provides high resistance against clogging and passage of fine dust.
It is possible to clean the filter using an integrated mechanical system; an external lever shakes the filter vertically and enables to clean the filter thoroughly and safely, maintaining constant suction performance and preventing any dispersion of dust in the environment.
COLLECTION UNIT
The vacuumed material is placed inside an AISI304 stainless steel roll-out container mounted on wheels, which makes it possible to dispose easily and safely of the vacuumed material.

Unedited feedback from customers who reorder Delfin MISTRAL 451 BL D2.
★★★★★
Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.

★★★★★
Asked about ferrite content on a Friday. A materials engineer answered Monday morning with actual data, not a sales pitch. That's why we keep ordering.

★★★★★
COA matches the bottle. PSD and flow are exactly what was on the sheet — we run it on a Renishaw 500Q and it hits density on the first try.
