Optimize your nutrient delivery with the Everfilt® F-Series Fertilizer Injection Tanks, the industry’s trusted solution for precision fertigation. Built for growers, landscapers, and agricultural professionals, the F-Series offers reliable, pump-free fertilizer injection designed for greenhouses, nurseries, drip irrigation systems, and low-volume irrigation setups.
What is the F-Series Fertilizer Injection Tank?
The Everfilt® F-Series Fertilizer Injection Tank is a precision fertigation system engineered to simplify nutrient delivery in agricultural irrigation. Unlike traditional pump-based systems, the F-Series uses existing line pressure to inject fertilizer directly into the irrigation stream, with no pumps, motors, or moving parts required.
This low-maintenance, energy-efficient solution ensures uniform nutrient distribution across crops, helping growers maximize yield while minimizing resource consumption.
Engineered for Simplicity and Durability
Each F-Series tank is constructed from 3-leg carbon steel for maximum stability and long-term durability, suitable for both indoor and outdoor agricultural environments.
Key Construction Features:
3M-134 NSF-approved epoxy interior for superior corrosion resistance
Industrial-grade fuze coat exterior with UV-resistant additives for extended service life
Available in 5, 15, 30, 45, & 75-gallon models
High-pressure options available for specialized irrigation systems
This rugged design ensures the tank performs reliably even under demanding agricultural conditions.
How the F-Series Fertigation System Works
The F-Series uses a pressure differential system to draw water into the tank, mix it with fertilizer, and inject the nutrient solution back into the irrigation line. By adding a flow control valve or flow meter, growers can precisely regulate the fertilizer concentration to achieve consistent, controlled feeding.
Operation Overview:
A regulating valve creates a pressure differential.
Water enters the tank & mixes with fertilizer.
The mixture is then distributed evenly through the irrigation system.
This hands-free fertigation method simplifies nutrient application while improving efficiency and crop health.
Industries That Rely on the F-Series Fertilizer Injection Tanks
The F-Series is used across a wide range of agricultural and horticultural applications. Whether you manage a commercial greenhouse, a nursery, or a landscape irrigation system, the F-Series delivers precision and reliability.
