Inward-Flow Mesh Panel Screen
No Underwater Transmission Parts | Baffles Prevent Short-Circuiting | Inward-Flow Mesh Panel Screen | Water Supply & Drainage Suspended Solids Interception
Product Overview
The Inward-Flow Mesh Panel Screen is a precision filtration machine engineered to intercept and remove smaller suspended and granular impurities in water supply and drainage systems. It serves as an advanced secondary clearing step for water that has already passed through coarse screens.
This equipment features a highly compact structure with minimal footprint, making it exceptionally easy to install and operate. Sewage flows into the machine through a water inlet hole at the lower water-facing end and exits through the side and bottom mesh panels, effectively trapping contaminants on the inner surface of the mesh for highly efficient solid-liquid separation.

Core Features & Benefits
- Zero Underwater Transmission Parts: Designed for easy maintenance and extended service life, with no transmission mechanisms located underwater. This prevents mechanical failures caused by long-term submersion or debris entanglement.
- Baffle Design Prevents Short-Circuiting: Strategically placed flow diversion baffles between the frame and channel walls guide flow while preventing unfiltered wastewater from bypassing the screen directly into post-filtration zones.
- Optimized Inward-Flow Interception: The "inward-flow, outward-exit" configuration ensures contaminants are firmly trapped on the inner mesh surface, preventing secondary spillage and ensuring efficient solid-liquid separation.
Frequently Asked Questions
Is the mesh hole size fixed? Can it handle different sizes of impurities?
The net size of the mesh holes is not fixed; it is "adjustable as needed". This allows the equipment to flexibly adapt to specific interception requirements for various suspended and granular impurities at different pump stations or treatment plants.
Since there are no moving parts underwater, how does the machine operate to clean the debris?
The machine consists of a drive unit, frame, traction chain, stepped mesh panel, and flushing system. Core power and drive components are securely positioned above water, utilizing traction chains to pull the mesh panel system upward for decontamination cycles while protecting mechanical components from harsh underwater environments.
