DuroDust™ | Industrial Dust Collection
DuroDust™ is the mobile dust collection system with non-vented, non-ducted, industrial dust collection technology. From silica dust to hexavalent chromium, it’s the safe, clean air solution for stone cutting, welding, sanding, grinding, painting, and coating preparation. The DuroDust is used for non-combustible dust only.
- St 0: Kst value 0 – no explosion. Typical of silica dust, welding-generated dust and thermally generated dusts from cutting processes.
For a complete clean air solution, pair DuroDust with:
Key Features
Negative pressure:
Pulls all particulate to the filtration system
Meets/Exceeds CFM Requirements:
Engineered airflow requirements from 13,500 CFM to 120,000 CFM and beyond, to achieve airflow from 50 FPM to over 150 FPM through the enclosure and ensure dust/smoke will not escape.
Advanced filtration system:
Designed with 4 stages of highly-efficient filtration captures all particulate to 1 micron and 99.7% of particulate to 0.3 micron.
Exceeds NESHAP 319:
Captures 100% of Hexavalent Chromium particles generated during surface preparation processes.
- First stage: Mesh pre-filter
- Second stage 3 ply particulate
- Third stage is 3 ply finer particulate
- Fourth stage is a NESHAP 319, MERV 15, MERV 16 or HEPA filter, depending upon requirements
Easy Assembly:
Nut and bolt panel assembly, easy panel on off speed dial, option for a lockable fused disconnect and C/UL/US Listed with a pre-wired control panel.
Taper Draft Airflow Technology:
Directs air down the center of the enclosure to send particulates to filter banks creating a regulated area.
Variable Frequency Drive:
Energy-efficient VFD with adjustable air speeds, doubles as a soft starter to eliminate the need for a motor starter.
Non vented returns air to the building
Yes, The DuroDust is a non vented system. Filtered air is returned to workspace.
