IAC designs and builds its own dust collection equipment. Each unit is custom-engineered based on your application. Our systems range from nuisance dust baghouses to large process gas systems. No project is too large or too small!
Baghouse Operating Principle
1. Solids laden air or gases enter the unit at the hopper or housing unit.
2. Air passes through the filter media.
3. Solids are retained on the filter media surface.
4. Filtered air is exhausted through the clean air plenum.
5. Cleaning cycle consists of a momentary blast of 90 to 100 psig compressed air.
a. Momentarily taking a row of bags off stream through pressure reversal.
b. Flexing filter bags.
c. Solids are released to fall towards hopper through rotary valve or other discharge equipment.
6. Cycle timer is adjusted to maintain approximately 3" to 4" water column pressure drop across the filter bags.
