Reverse Osmosis RO DI Dental Autoclave Filter RODI ROP4-DJ with Booster Pump

4 STAGE REVERSE OSMOSIS RO DI DENTAL AUTOCLAVE FILTER RODI ROP4-DJ WITH PRESSURE BOOSTER PUMP
4-Stage Demineralising Water Purifier + Deioniser + Booster Pump + All Filters

This RO DI system is assembled locally using high-quality, approved parts. Each unit is individually flushed, the membrane is tested, and the complete system is pressure tested at our factory before dispatch.

The ROP4-DJ model includes an integrated diaphragm booster pump with transformer to maintain constant optimal pressure on the RO membrane — ensuring peak purification performance and consistent output, even where mains water pressure is low.

The system includes a final-stage mixed-bed DI resin filter. Production volume depends on the membrane selected in the drop-down menu. With the booster pump operating, the system achieves optimal water flow and efficiency at the correct membrane pressure.

This filter produces the purest possible water, reducing Total Dissolved Solids (TDS) to between 0–0.5 ppm, removing 99.9%–100% of all substances and impurities.

Why Choose the RODI Reverse Osmosis Dental Autoclave Filter (ROP4-DJ)?

The ROP4-DJ Reverse Osmosis Deionisation System is a high-performance, 4-stage purification unit specifically designed for dental autoclaves, sterilisation equipment, and dental practices requiring ultra-pure, demineralised water.

Assembled and tested locally, it delivers 0–0.5 ppm TDS water, eliminating virtually all dissolved solids, minerals, and contaminants — preventing autoclave scaling and ensuring optimal steriliser performance.

With its integrated booster pump, the ROP4-DJ guarantees constant pressure and high flow rates through the membrane, maintaining consistent water quality even in low-pressure installations.


Compact Design and Reliable Performance

Built from high-quality, BPA-free food-grade components, this compact 4-stage system combines sediment filtration, carbon adsorption, reverse osmosis, and deionisation to produce pure, sterile-grade water. The built-in booster pump enhances pressure stability, increases membrane life, and ensures maximum efficiency.


Seamless Integration and Compliance

Supplied as a complete kit ready for installation, the ROP4-DJ is AS3497 WaterMark compliant and factory pressure-tested prior to dispatch. The system includes all fittings, valves, and accessories required for professional installation in dental environments.

Covered by a 36-month warranty, this RO DI unit offers unmatched purity, pressure-stable performance, and long-term reliability — ensuring your autoclave and instruments operate with the highest quality water possible.
