Product Overview

This is a highly integrated, modular aquarium water-outlet system. It ingeniously combines three core functions—rainfall-style dispersed water output, efficient oxygenation via the Venturi effect, and terminal water-flow diffusion—into a single unit. By selecting different outlet terminals (such as the purple diffuser head), users can easily achieve water-mist oxygenation, powerful aeration, or gentle water flow, making this one device capable of multiple functions. It is an intelligent solution for optimizing dissolved oxygen levels, water circulation, and water quality in aquariums.

Design Highlights

1. Three-mode intelligent switching:
   • Rainfall mode: A multi-tube parallel design creates a uniform water curtain for gentle oxygenation while minimizing water-impact forces.
   • Venturi oxygenation mode: The core vertical column features a Venturi tube structure that draws in large volumes of air during water discharge, generating fine, dense bubbles for powerful oxygenation and removal of surface oil films.
   • Terminal diffusion mode: The replaceable purple terminal diffuser head—with vertical slots or tooth-like structures—further breaks up the water stream to deliver ultra-gentle water flow.
2. Modular quick-release design: The system consists of multiple components, including an inlet elbow, the Venturi body, a blue biochemical filter cartridge (for supporting bacterial colonization and noise reduction), and terminal nozzles. These parts connect via snap-fit or threaded joints, allowing for rapid disassembly, cleaning, and function switching without tools.
3. Industrial-grade robust design: The main structure is made from durable materials, with corrosion-resistant metal accents. The blue biochemical filter cartridge enhances biological filtration and stabilizes water flow. The overall construction is sturdy and can handle high pump flow rates.
4. Height and flow direction adjustable: The entire outlet assembly can be adjusted in height and angle using brackets or suction cups, and the Venturi’s air intake can be finely tuned via valves (such as the purple valve shown), ensuring precise adaptation to the specific needs of different aquariums.

Technical Specifications

• Compatible pipe diameter: Adapts to standard flexible hoses with an outer diameter of 16 mm (12/16 tubing) or 18 mm (16/22 tubing).
• Core modules: Adjustable rainfall nozzle assembly, Venturi oxygenation body, blue biochemical filter cartridge, and multi-functional terminal diffuser head (e.g., the purple model).
• Primary materials: ABS, acrylic, and stainless steel for the main body; food-grade silicone or plastic for connectors.
• Operating method: Powered by a water pump—no additional power supply required.

Application Scenarios

1. High-oxygen-demand fish keeping: Provides robust dissolved-oxygen support for high-oxygen-demand species such as goldfish and koi, helping to prevent oxygen deficiency.
2. Planted tanks and eco-system tanks: Uses rainfall or gentle diffusion modes to create a slow-flow, high-oxygen environment for aquatic plants, light-colored fish, and shrimp.
3. Eliminating stubborn oil films: The Venturi mode not only boosts oxygenation but also effectively draws in and removes surface oil films.
4. Comprehensive water-flow management for medium-to-large aquariums: A single system meets multiple needs—oxygenation, water circulation, and water-quality purification—while simplifying the tank’s equipment setup.
