Aluminum Dust Housekeeping Vacuum
The solution had to comply with the NFPA 660 Class II, Group E Requirement
The Problem
A large manufacturer known for making aluminum body parts for BMW and Honda needed a cleanup vacuuming solution for the aluminum dust being generated at multiple work stations. Because aluminum dust is highly explosive, they were already aware that no chances could be taken when considering vacuuming solutions.
Class II, Group E OSHA Requirement
In Metal Dust Housekeeping Applications, NFPA 660 states that “The use of portable vacuum cleaners shall comply with 22.8.4.2.2. (B)*Due to the inherent hazards associated with portable electric vacuum cleaning systems, the equipment used for cleaning shall be identified for use in Class II, Group E atmosphere.”
The Solution
We recommend the Tiger-Vac® EXP1-20L (DT) RE HEPA (MFS), as it is rated for Class II, Group E.
Its 110V operation and portability make it user-friendly. It features a TEFC motor that is compatible with clean rooms. A conductive poly liner recovery bag is optional and is intended for dry recovery only.
It includes a detachable tank (DT) and a manual Filter-Shaker (MFS).
The customer reported that the vacuum was successful, and they have since ordered more units.
