4,000 GPD Static Manual Pure Water RO System – Floor Standing

4,000 GPD Static Manual Pure Water RO System – Floor Standing

Professional high-output 4-stage reverse osmosis filtration system producing up to 4,000 gallons (18,000 litres) of pure water per day.
Built on a durable aluminium self-supporting frame, this floor-standing system is ideal for commercial window cleaning businesses and multi-vehicle operations.

System Overview

Designed for large-scale pure water production, this commercial static RO system delivers reliable, low-maintenance filtration with fast refill times of approximately 350 litres per hour (depending on water pressure).

Perfect for garages, workshops, depots, and commercial cleaning setups requiring continuous high-volume pure water production.

4-Stage Filtration Process

Stage 1 – Sediment Filtration

Removes dirt, sand, rust, and particles using a high-quality 20” sediment filter.

Stage 2 – Carbon Filtration

Carbon block filter removes chlorine, VOCs, pesticides, and harmful contaminants.

Stage 3 – Reverse Osmosis

Dual 40” SRO-4040 low-pressure membranes deliver ultra-efficient filtration with up to 99% rejection rates.

Stage 4 – DI Resin Polishing

11L DI vessel removes remaining TDS for spotless pure water results.
