Wet Immersion of Aluminum and Titanium Dusts for Inertization
HAZDUST Wet Downdraft Table
The HAZDUST Wet Downdraft Table is designed to capture explosive metal dust such as aluminum, titanium, magnesium, and commercial alloys. The table meets the codes and requirements from NFPA484. Each unit is rigorously tested before it leaves our shop.
The wet portion of the unit is constructed from 304 stainless steel for long lasting life.
The HAZDUST Downdraft tables are available in: 36" x 36", 36" x 48", and 36" x 72". These are table-top dimensions.
Conductive metal powders can be extremely hazardous. If your Dust Collection provider isn't aware of this then you need a specialist and not a sales person.
Ceiling Mounted Ambient Dust Collectors are unsafe for Titanium Dust
Ambient-style dust collection can pose serious risks when it comes to handling titanium dust. A simple search on "titanium dust cloud in machine shops" reveals the critical nature of airborne titanium particles. These particles are highly pyrophoric, meaning they can ignite spontaneously upon contact with air, potentially leading to a powerful explosion triggered by even a minor spark or heat source, including static electricity. Therefore, stringent safety protocols are essential when dealing with titanium dust in a machine shop setting.
Titanium dust boasts a KST value exceeding 300, far surpassing the explosivity level of polyurethane dust at 156 KST. Despite these dangers, it's concerning to observe the use of ceiling-mounted Ambient Dust Collector systems in machine shops to manage titanium dust plumes. These installations are ill-suited for capturing explosive dust due to numerous inherent limitations.
The recommended course of action is to conduct a Dust Hazard Analysis (DHA) and adhere to the guidelines outlined in NFPA 484 for handling combustible dust. If you are unfamiliar with these protocols, worry not, as we specialize in this area. Contact us today at (800) 635-0298 for expert guidance on implementing a safe and efficient solution aligned with NFPA 484 standards.
Aluminum, Magnesium, and Titanium are Combustible When Finely Sanded
Aluminum, magnesium, and titanium become highly combustible when finely sanded, posing a significant explosion risk if ignited by sparks or static electricity. Immersion systems are designed to neutralize the metal dust by submerging it in a liquid bath.

Titanium Dust Collection
Water Acts as an Accelerant in Titanium Fires
Water acts as an accelerant in titanium fires. We recommend use of a neutralizing oil in place of water for inertization of conductive titanium particles. Water is not recommended by NFPA 660.
Ducted Wet Collectors
NFPA 660 High-Low Water Shut-Off and Alarm
Ducted custom Wet-Collector for evacuating titanium dust from a robotic cell.
Conductive Dust Removal from Robotic-Cell Applications
Once we learn the details of your application we will send a detailed quote with specifications. This usually starts with a teams chat and gathering of details. We come up with a proposal that we can quantify with math and referencing of safety regulations.
We have a full range of wet downdraft and ducted wet collectors for safe capture of aluminum dust and other conductive metal powders. Our Wet Collection ducted systems are designed to be used indoors in manufacturing and research locations to collect explosive metal dusts from various processes. We have a lot of experience with automation and robotic manufacturing systems as well as Aerospace, Defense, Research, and countless others. We will also be able to help you with OSHA and NFPA compliance by showing you how to deal with each specific explosive metal dust application.
