F-Series Fertilizer Injection Tanks – Precision Fertigation for Greenhouses, Gardens & Low-Volume Irrigation Systems

The Everfilt® F-Series Fertilizer Injection Tanks are a trusted choice for professionals in greenhouse cultivation, commercial gardening, drip irrigation, and fertigation-based agriculture. Designed for efficient, pump-free fertilizer injection, the F-Series provides an easy-to-use, low-maintenance solution for controlled nutrient application directly into irrigation lines.

Engineered for Fertigation Simplicity

With a 3-leg carbon steel construction, these units are built for stability and durability in both indoor and outdoor environments. Ideal for low-volume drip systems, the F-Series Fertilizer Injection Tank utilizes existing line/system pressure to inject either dry or liquid fertilizer, eliminating the need for external pumps or electrical connections. This passive operation reduces complexity and enhances reliability, especially in remote or resource-limited growing operations.

Ideal for Agricultural Professionals

Whether you're managing a greenhouse tomato operation, a commercial nursery, or open-field drip irrigation, the F-Series Fertilizer Injection Tank simplifies fertigation while allowing for precise control. By incorporating a flow control valve or flow meter, users can accurately manage the amount of nutrient solution delivered. A pressure differential caused by a regulating valve directs water into the tank, where it mixes with fertilizer and exits into the irrigation system, ensuring consistent, uniform application.
