Unrestricted Flow. Consistent Feeding.

The High Flow Cup is a performance-driven upgrade for the aF4, engineered to eliminate flow restrictions and improve feeding consistency. Every design change targets real-world pain points—so your system runs cleaner, smoother, and more reliably.

What’s Improved

Eliminated Intake Blockages
The previous cup design's internal prongs have been removed to prevent food from accumulating and forming blockages. This ensures a clear, uninterrupted intake path and more dependable feed cycles.

Refined Flow Path
The internal geometry has been optimized to create a smoother transition from reservoir to outlet. This reduces the chance of kinks or constrictions at the exit—one of the primary causes of inconsistent dispensing.

Integrated Tube & Probe Bracket
A built-in positioning bracket secures both the feed tube and temperature probe. No more guesswork or repositioning when the reservoir is full—placement is consistent and repeatable every time.

Compatibility

Designed as a seamless upgrade with zero friction:

• Compatible with all existing aF4 lids
• Works with the current reservoir rack
• Fully backwards compatible with all aF4 generations

No adapters. No modifications.

Why Upgrade

The original aF4 cup established a reliable foundation for automated frozen feeding. The High Flow Cup builds on that platform with targeted refinements that further improve flow consistency, reduce variability, and simplify setup.

For users looking to optimize performance and minimize intervention, this upgrade delivers a more streamlined, repeatable feeding experience—especially in demanding or high-load feeding scenarios.
