Rain Water Harvesting Filter

High-Efficiency Rainwater Harvesting Filters

Our rainwater harvesting filters are manufactured using highly durable, food-grade materials and feature an advanced self-cleaning mechanism that automatically flushes out debris, ensuring consistent filtration and minimal maintenance.

Key Features & Benefits

  • Self-Cleaning Technology: Automatically removes dirt and debris, maintaining efficient water flow.
  • 360° Union Rotation: Flexible installation with full rotation capability, making the filter suitable for all site conditions.
  • Easy Installation: Wall-mountable and self-installable with simple, easy-to-understand instructions.
  • Advanced Filtration Principle: Operates on the principles of cohesion and centrifugal force, ensuring effective filtration even at varying rainfall intensities without loss of efficiency.
  • Wide Application: Filtered water can be diverted to underground sumps, existing borewells, or other water storage reservoirs.
  • No External Power Required: Works purely on gravitational force and does not require electricity or external energy.
  • Low Installation Height: Requires a minimal gravitational head of just 1 foot, making it suitable for installation on any type of building.
  • No Moving Parts: Eliminates wear and tear, ensuring long life and making it a one-time, economical investment.
