Low-Maintenance Filtration with Automatic Valveless Gravity Filters
FILTEC’s Automatic Valveless Gravity (AVG) Filter solutions provide efficient, self-operating water treatment for councils, industries, and facilities. Using gravity-driven flow and an automatic backwash cycle, they eliminate external pumps and valves. This low-energy, cost-effective solution ensures high water quality with minimal intervention, ideal for drinking water and industrial tertiary filtration processes.
Our Automatic Valveless Gravity Solutions
Drinking Water Filtration Systems
FILTEC’s AVG Filters deliver consistent, high-quality drinking water by removing suspended solids, iron, and manganese. These systems ensure safe, compliant water with minimal operator intervention, while the self-cleaning mechanism reduces maintenance costs and enhances reliability.
Industrial Process Water Treatment
For manufacturing and processing industries, AVG Filtration ensures stable water quality, preventing scaling, fouling, and equipment damage. These gravity-driven systems provide an efficient and cost-effective solution for industries requiring continuous, high-purity water.
Groundwater & Surface Water Filtration
Ideal for treating bore and surface water, AVG Filtration effectively removes particulates and oxidised iron and manganese. An upstream oxidation step, typically with chlorine, is required to convert dissolved iron and manganese into filterable forms. These self-operating filters offer a robust solution for maintaining clean and clear water.

How AVG Filters Works
Automatic Valveless Gravity Filtration operates without mechanical pumps or valves, using gravity to trap contaminants. As water flows through the media, head loss builds until reaching a set threshold, triggering an automatic backwash with stored filtered water. This ensures continuous operation without external intervention, making it a reliable, self-sustaining water treatment solution.
FAQs
What makes AVG Filtration different from conventional filtration?
AVG Filtration eliminates the need for automated valves and backwash pumps, relying on gravity-driven processes to maintain efficiency. This reduces energy costs, maintenance needs, and system complexity.
How often do Automatic Valveless Gravity Filters require maintenance?
