How a High-Capacity Bag Filter Feeder Works
A high-capacity bag filter feeder is installed on a bypass loop connected to the primary piping system. Water flows through the pressure vessel, where suspended solids are captured by the 25-micron filter bag before clean water returns to the system. At the same time, treatment chemicals can be safely introduced into the vessel to support corrosion protection, scale prevention, and overall water quality management.
This combination of filtration and chemical treatment helps maintain cleaner system water, improve heat transfer efficiency, and reduce operating costs over the life of the system.
Ideal For
The FHC-DB-2HD is recommended for:
- HVAC contractors
- Mechanical contractors
- Facility managers
- Building engineers
- Water treatment professionals
