High‑Efficiency Low‑Pressure PP Folded Filter for Pharmaceutical Use
Details
The RFA Series Direct‑Back Return Line Filter is a low‑pressure spin‑on hydraulic filter directly installed on the oil tank top for hydraulic system return‑line filtration. It removes solid contaminants such as metal chips and dust from return oil, protecting hydraulic pumps, valves and other precision components, while ensuring the cleanliness of hydraulic oil in the tank. It features direct‑mount installation, simple structure and easy maintenance, widely used in general‑purpose hydraulic stations, machine tools, construction machinery and lubrication systems.
Core Features
Direct Back‑Mount Design: Installed vertically on the oil tank top, saving pipeline space, compact layout.
Spin‑on Quick‑Change Filter Cartridge: Thread‑on filter element, easy replacement without draining tank oil, reducing maintenance downtime.
Built‑in Bypass Valve: Automatically opens when the filter is blocked, ensuring continuous oil circulation and system safety.
Clogging Indicator Port: Reserved port for installing pollution transmitters, real‑time monitoring of filter service status.
Wide Compatibility: Matches RFA standard spin‑on filter cartridges, filter media optional (cellulose paper, glass fiber, stainless steel mesh).
Wide Working Range: Max working pressure 1.6 MPa, temperature range −30 ℃ ~ 90 ℃, suitable for most industrial hydraulic systems.
