JLW-4200
1. What is the JLW-4200?
A professional ozonation system for pools, spas, tanks, and water treatment applications.
It produces 4,200 mg/h of ozone, offering advanced disinfection, oxidation, and water clarity.
Designed for professional installers, featuring modular components adaptable to various hydraulic conditions.
Designed and assembled in the U.S.A.
2. Venturi Injection System (Pro and Advanced Kits)
Utilizes a Venturi injector to efficiently mix ozone into the water.
Operates via differential pressure (ΔP) to generate a vacuum and draw in the ozone.
Advantages of the Venturi system:
Higher absorption efficiency
Reduced ozone loss
Faster oxidation
Requires no external air pump
The Direct Diffusion Kit version does not utilize a Venturi injector, as it features an internal 5 L/min air pump that allows for ozone injection at a depth of 3 feet.

3. Hydraulic Requirements
The Venturi injector requires a ΔP of 0.3–0.7 bar (5–10 psi) to generate a stable vacuum. Recommendations based on manifold size:
1" → Spas and small systems
1.5" → Residential pools
2" → Medium/Commercial pools
Install in a bypass configuration, adjusting valves to direct sufficient flow through the venturi.
4. Field Adjustment Procedure
Open all valves
Gradually restrict the main line
Increase flow through the venturi
Verify stable suction
Leave the system operating via the timer
5. Real-World Operating Conditions
The system is designed to operate under:
Variable pressures
Varying pipe diameters
Humid environments
Continuous daily operation
6. Installation Tips
Use an air dryer (included in Pro/Advanced kits)
Keep piping runs short
Install a check valve
Ensure adequate pressure

7. Key System Differences
It is not just a generator: It is a complete ozone injection system, designed for real-world installations—ranging from spas to full-sized swimming pools.
8. Available Kits
Basic Kit
4200 mg/h Generator
Digital timer
Accessories and check valve → Spas, hot tubs, small tanks, aquariums
Pro Kit
All of the above +
Dual air-drying system → Small/medium pools, commercial spas, humid climates
Advanced Kit
All of the above +
Manifold with venturi (1", 1.5", 2") → Residential and commercial pools
Direct Diffusion Kit
Generator + internal pump + diffusers → Tanks, cisterns, aquariums, systems without a return line
Note:
The Direct Diffusion Kit is designed for simple, standalone operation, eliminating the need for venturi injectors or complex plumbing.
With its built-in air pump, ozone is delivered directly into the water through diffusers, providing an efficient solution for systems without hydraulic circulation.
Hydraulic Requirements Table
| Manifold Size | Venturi Size | Typical Flow Rate | Recommended ΔP | Minimum Pressure | Application |
|---|---|---|---|---|---|
| 1" | 1" | 4–6 m³/h | 0.3–0.5 bar | ≥1.5 bar | Spas and small pools |
| 1.5" | 1" | 6–12 m³/h | 0.3–0.7 bar | ≥1.8 bar | Residential pools |
| 2" | 1" | 10–18 m³/h | 0.4–0.7 bar | ≥2.0 bar | Medium / commercial pools |
9. Digital Timer Control
Easy programming. Injection cycles can be programmed and customized. (Factory pre-set: 8 cycles/day, 1 hour each.)
It enables:
Shorter cycles
Nighttime operation
Intensive treatments
Easy to use, stable, and reliable
Precise control = improved efficiency and extended service life
