How It Works

During normal operation:

1. During normal operation, the dust laden air from the plant travels down the supply duct.


2. The dirty air then enters the COMBIFAB Material handling fan.


3. The dust then enters the hopper section of the filter.


4. As air slows down within the hopper, the heavier dust particles fall down into the inside of the filter bags.


5. The remaining dust then travels up into the inside of the filter bags.


6. The air, which originated from the plant, is now clean and passes through the filter bag into the surrounding atmosphere.

While Cleaning:

1. The NFP Closed filter must also clean “off-line”, when the COMBIFAB fan has stopped rotating.


2. With Semi-Automatic cleaning, the reverse air ‘regeneration’ fan 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, 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.


5. A damper on the hopper inlet closes to prevent dust from blowing back down the duct work.
