During Normal Operation
1. During normal operation, the dust laden air from the plant travels down the suply duct (1)
2. The dirty air then enters the COMBIFAB (2) material handling fan
3. The dust then enters the hopper section (5) of the filter
4. As air slows down within the hopper, the heavier dust particles fall down into the inside of the collection bags (6)
5. The remaining dust then travels up into the inside of the filter bags (4)
6. The air, which originated from the plant, is now clean and passes through the filter bag into the surrounding atmosphere (3) |
 |
While Cleaning (NFP Open)
1. The NPF Open may only clean "off-line", when the COMBIFAB fan (2) has stopped rotating
2. The NPF Open is cleaned by applying physical force to the outside of the filter bag (4) which, in effect, shakes them
3. The dust cake, which hangs on the inside of the filter bag, falls into the hopper section and then into the collection bags below (6)
|  |
While Cleaning (NFP Open)
1. The NPF Closed filter must also clean "off-line", when the COMBIFAB fan (2) has stopped rotating
2. With Semi-Automatic cleaning, the reverse air regeneration fan (7) is turned on and off by the operator. When Fully-Automatic cleaning is selected, a PLC control panel cycles the regeneration fan on and off
3. The dust which remains on the inside of the filter bag, (4) after the initial shake, is removed by the airflow generated by the cleaning fan
4. The dust which is removed during the cleaning cycle falls into the collection bags/barrels (6)
5. A damper on the hopper inlet closes to prevent dust from blowing back down the duct work

The Heart of the system
A filter is only as good as the bag it uses. This is the component that provides the filtering while allowing clean air to pass through with the least possible resistance and, therfore, the lowest possible consumption of
energy-even after several thousand hours of operation |
 |
 |
Efficiency and low energy consumption
Superbag is polyester filter bag. A patented weaving technique in tubular format give the filter bag a surface which can cope with varying dust loads and with virtually any type of dust. Better filtering efficientcy is
achieved with this unique filter media which provides low pressure drop, and low energy consumption. |
Strength and durability
The special shape of the SUPERBAG helps to ensure that the high efficiency and effectiveness of the NFP filter system is maintained even after long periods of operation. The durability is the result of the patented
construction, strong polyester fiber and seamless body. These features also help make cleaning of the filter bag very easy. |
Antistatic
SUPERBAG's interwoven carbon fiber wire provides higher anti-static properties - both on the surface and inside - than traditional filter bags. This reduces the risk of fire and explosion as fine particles are removed. |
