PRO HEPA 20
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.
FEATURES
PRO HEPA 20 has more capacity (20-Gallons) than any other HEPA Vacuum in its class. Equipped with an individually tested and certified HEPA filter, designed for the professional contractor recovering a wide range of materials including asbestos, lead, silica and other hazardous materials. Rotational molded polyethylene tank with built-in handle, large rear wheels and front swivel casters allow easy transporting even with a full tank of debris or liquids. A reliable liquid shut-off allows the operator to vacuum liquids uninterrupted until the tank is full and without risking damage to the HEPA filter.
• 2 HP commercial grade, 2 -stage bypass motor
• 120V outlet with on/off activation of vacuum motor using power tool or other appliance
• 50-foot power cord for working large areas without stopping to locate an outlet
• Individually tested and certified HEPA Filter, minimum efficiency of 99.97% at .3 microns based on particle count test method, IEST-RP-CC001
• Dacron Filter Bag prevents interruptions due to clogging and loss of airflow

Full documentation — TDS, SDS, batch COA, and parameter sets for the major LPBF platforms. Everything you need for qualification under AS9100 / ISO 13485 workflows.
We atomize our own. Custom variants on request.
Tighter PSD, modified chemistry, custom blend? Our ATO atomization lab runs custom batches in 3–4 weeks. Biocompatible, refractory, proprietary — all in-house, verified before ship.
From process engineers running PRO HEPA 20
Unedited feedback from customers who reorder PRO HEPA 20.
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.
