Product Introduction

This is a 3D-printed outlet modification component specifically designed to fit “Wind and Fire Wheel” and other similar aquarium circulators. Featuring a unique C-shaped snap-lock structure, it can be directly and securely mounted onto the device’s original inlet/outlet ports, redirecting the originally vertically downward water flow into a horizontally or diagonally adjustable stream. This effectively optimizes the water circulation path within the aquarium, increases dissolved oxygen levels, and reduces direct water impact on in-tank decorations and aquatic life.

Design Highlights

1. C-shaped Quick-Release Snap Lock: An innovative open C-shaped ring design that easily slips over the device’s existing port. By simply rotating the lock, the water outlet direction can be continuously adjusted through a full 360-degree range—no tools required for installation or adjustment, making it convenient and efficient.

2. Duckbill-Shaped Flow-Directing Nozzle: The flattened duckbill-shaped outlet at the end disperses the water into a soft, uniform sheet-like spray, increasing the contact area between water and air to enhance oxygen dissolution while significantly reducing the force of the water jet.

3. Integrated, Robust Structure: The entire component is manufactured as a single,一体printed part with no screws, seams, or other small detachable parts, ensuring safe and reliable underwater use and preventing accidental injury to fish or leaks caused by loosening.

4. Adaptability and Targeted Design: Specifically engineered to match the pipe diameter and external shape of “Wind and Fire Wheel”-type devices, guaranteeing a tight fit with no excessive play at the connection point, thus perfectly replacing or upgrading the original outlet component.

Technical Specifications

• Compatible Devices: Designed specifically for the 18 mm inlet/outlet ports of “Wind and Fire Wheel”-type aquarium circulators.

• Core Materials: PLA / PETG / ABS (for 3D printing; PETG or ABS are recommended for long-term underwater use).

• Connection Method: C-shaped rotary snap lock, allowing direct insertion and secure fixation.

• Main Functions: Continuous adjustment of water flow direction, gentle dispersion of the water stream, enhanced oxygenation, and adaptive retrofitting.

Application Scenarios

1. Optimizing Water Flow in “Wind and Fire Wheel” Systems: Directly replaces or installs on existing equipment to transform vertical water flow into horizontal circulation, promoting overall water movement throughout the tank and preventing stagnant zones.

2. Oxygenation for Small and Medium-Sized Tanks: The duckbill nozzle breaks up the water flow to introduce more air, providing supplemental oxygenation for small tanks, shrimp tanks, or high-oxygen-demand fish tanks—eliminating the need for an additional air pump.

3. Applications in Planted Tanks and Eco-Aquariums: Provides a gentler, more diffused water flow that is ideal for aquatic plant growth, avoiding strong currents that could topple decorations or disrupt plant health.

4. Keeping Fish with Specific Behavioral Preferences: Creates a more suitable water flow environment for ornamental fish that prefer slow-moving water or require specific flow directions, such as Corydoras catfish and certain lanternfish species.
