Venturi Tube Oil Film Remover Outlet

Product Introduction

This is an outlet accessory specifically designed to remove oil film from the aquarium water surface. It does not integrate an aeration function. Its core principle is to utilize the Venturi effect to generate negative pressure during water outflow, drawing in surface water containing oil film and mixing it into the main water flow. This mixture is then carried into the filtration system for physical filtration, thereby continuously and automatically cleaning the water surface and maintaining clear, aesthetically pleasing water

Design Highlights

1. Venturi Negative Pressure Oil Film Removal: The core design is based on the Venturi effect. As water flows through a specific narrow section of the outlet, the flow rate accelerates and pressure drops, thereby creating negative pressure at the connected oil film intake, which reliably draws the surface oil film into the water flow
2. Adjustable Flow and Anti-Suction Design: The flow rate at the oil film intake is typically adjustable (e.g., by rotating the bottom component), allowing users to regulate suction power based on oil film severity and pump output. The intake is equipped with fine grilles or slits, effectively preventing small fish, shrimp, or aquatic plants from being drawn in
3. Surface Agitation and Self-Floating Structure: Some designs feature a rotating, float-type oil film removal head that continuously agitates the water surface, breaking down the oil film layer. It automatically rises and falls with the water level, ensuring it always operates on the uppermost water layer
4. Easy Integration and Compatibility: Can directly replace the existing outlet. It has an outer pipe diameter of 17mm. The structure is simple, requires no additional power, and is entirely driven by the filtration pump

Application Scenarios

1. Aquascaped and Ecological Tank Surface Maintenance: Effectively removes surface oil film generated by decomposing feed and fish waste, increasing light transmittance and benefiting aquatic plant photosynthesis
2. Small to Medium Aquarium Water Quality Management: Offers an integrated and simple surface cleaning solution for tanks that do not have a separate oil film remover installed
3. Preventing Hypoxia Caused by Oil Film: Although it does not actively aerate, removing the oil film that impedes oxygen exchange indirectly benefits dissolved oxygen in the water
4. Alternative to Independent Oil Film Removers: Saves in-tank space and equipment, simplifying the aquarium's aesthetic
