MikroPul Collectors Boost Many Safety Features
MikroPul ads point to their collectors as a safer alternative. MikroPul’s RAF-IS collector doesn’t use compressed air. It cleans bags via low pressure, high volume reverse air flow. The cleaning air is drawn from just-filtered air in the outlet plenum. A low horsepower centrifugal airfoil fan propels the air through nozzles attached to a distribution plenum continuously rotating above the bags. This simple cleaning mechanism has been proven in hundreds of installations to be very reliable.
Unlike other reverse air filters, all electrical components on the RAF-IS are located outside the filter housing. This eliminates any chance of a spark inside the housing from electrical devices. It is said to have more safety features than any other collector. The RAF-IS leads the industry in the scope and effectiveness of its safety features.
This is especially true for users of coal with a high Kst value, like PRB coal. A fire or explosion in the dust collector will shut down production and could be harmful to personnel.
In addition to the above, you get:
Their proprietary form-lock bag and cage design, which ensues positive grounded cages per latest NFPA 77 code;
Explosion venting per latest NFPA 68-2002 codes;
Built-in deluge nozzles per latest NFPA 15 codes;
Efficient involute inlet is clad with replaceable anti-spark wear-resistant plates. In addition, the inlet creates a cyclonic flow that sweeps the hopper clean;
Similarly, the rotating distribution plenum above the bag plate keeps it clean;
Ledgeless design throughout the collector prevents dust accumulation, which can lead to spontaneous combustion.
