Product Overview
The J.L. Wingert F-DB-12HD Dome Bottom 25 Micron Filter Bypass Feeder is a high-capacity filtration and chemical treatment solution designed for commercial HVAC systems, industrial process water applications, boiler systems, and closed-loop heating and cooling systems. Engineered to remove suspended solids while supporting water treatment programs, this bypass filter feeder helps improve water quality, protect equipment, and extend the life of critical system components.
Built with heavy-duty carbon steel construction and a dome-bottom vessel design, the F-DB-12HD offers dependable performance in demanding environments where maintaining clean, properly treated system water is essential for operational efficiency.
Why Choose the J.L. Wingert F-DB-12HD?
Water quality plays a critical role in the performance of closed-loop systems. Contaminants such as rust, scale particles, sediment, and debris can reduce efficiency, restrict flow, and increase maintenance costs. The F-DB-12HD helps remove these contaminants while allowing operators to introduce treatment chemicals directly into the system.
Key Benefits
✔ Captures particles down to 25 microns
✔ Supports corrosion and scale prevention programs
✔ Helps improve heat transfer efficiency
✔ Reduces maintenance requirements
✔ Extends equipment service life
✔ Heavy-duty construction for long-term durability
✔ Ideal for commercial and industrial systems
✔ Easy chemical addition and filter replacement

How a Filter Feeder Works
A filter feeder is installed on a bypass line connected to a closed-loop water system. Water continuously circulates through the vessel where suspended solids are captured by the filtration element. At the same time, treatment chemicals can be introduced into the vessel to help control corrosion, scale formation, and biological growth.
This combination of filtration and chemical treatment helps maintain clean system water while improving the performance and longevity of HVAC and industrial equipment.
