P/N: GU12/BC03
This capture velocity drum hood offers a pre-engineered control for personnel and environmental safety and protection. The capture velocity drum hood attachment for the MAC-21 facilitates the opening and inspection of 85 gallon drums. The hood incorporates a clear viewing section that extends completely over the drum top, or may be retracted to about 1/2 of the drum top to facilitate access or inspection of drum contents. Air flow is drawn into the hood, over the drum top at a capture velocity of about 85 FPM. A screen and prefilter installed in the hood arrest material or particles that enter the MAC-21 inlet plenum.
In operation, the MAC-21 with the Drum Hood is positioned over the drum. A large poly bag is taped to the front of the drum. The unit is started and the drum lid retainer and drum lid (or bung) is removed and slipped into the poly bag. After inspection or sampling, the lid is slipped from the poly bag and placed back into the drum and secured.
The MAC-21 is a modular ventilation unit capable of providing High Efficiency Particulate Air (HEPA) filtration with 99.97% efficiency @ 0.3 microns.
The MAC-21 is an assembly of three modules:
1) Power Module- a direct drive blower/motor and base assembly;
2) Filter Module- prefilter & HEPA filter housing assembly;
3) Quick-Mount Cart- handling cart and mounting platform for the power module and filter module.
This unit has been evaluated to the applicable CSA standards for use in the United States under product Class 3812-81 (Fans and Blowers) and Canada under product Class 3812-01 (Fans and Blowers).
