Product Description
This 20-inch multi-stage water filtration system is specially engineered for robotic base stations and autonomous outdoor equipment.Designed to support unmanned operations, it integrates PP, GAC, CTO, KDF, UF, and resin filter cartridges to effectively remove sediment, chlorine, heavy metals, and hardness.
It ensures a stable, clean, and reliable water supply for robotic maintenance tasks such as solar panel cleaning, equipment washing, and long-term outdoor operation—even in harsh and remote environments.
Key Advantages
1. Multi-stage filtration for complex water conditions
2. Heavy-duty design for outdoor use
3. Protects pumps, pipelines, and equipment
4. Standard 20” cartridges for easy replacement and upgrade
