Maintain perfect humidity levels and regulate rising spring temperatures in your greenhouse with the Netafim CoolNet Pro Fogger (High Pressure). Engineered for commercial-grade cooling systems, this cross-shaped fogger utilizes four high-performance nozzles to produce an ultra-fine 65-micron mist. This microscopic droplet size ensures rapid evaporation, cooling the air and boosting humidity without soaking your plants or the soil below. This specific high-pressure model features an integrated orange-pin check valve that requires 58 PSI to open, guaranteeing absolutely drip-free operation the moment your high-powered system shuts off. Suspend the fogger from your overhead 1/2" mainline tubing using the required Micro-Sprinkler/Fogger Hanging Assembly.
Review the exact performance metrics to integrate the High-Pressure CoolNet Pro into your overhead climate control system.

Build your overhead greenhouse climate system correctly for optimal evaporation.
Step 1: Prep the Overhead Mainline
Using a DripWorks key punch, create a clean hole in your suspended 1/2-inch or 3/4-inch poly mainline tubing. Space these holes exactly 36 inches apart over your benches.
Step 2: Attach the Hanging Assembly
Insert the barb of your Micro-Sprinkler/Fogger Hanging Assembly firmly into the punched hole. A weighted drop-tube assembly is necessary to keep the fogger perfectly level.
Step 3: Connect the CoolNet Fogger
Press the Netafim CoolNet Pro Fogger securely onto the bottom female connection of the Hanging Assembly.
Step 4: Ensure Adequate Pressure
Ensure your high-pressure pump system can deliver a minimum of 58 PSI to pop the check valves open, maintaining around 60 PSI for the ideal 65-micron droplet size. A 140-mesh filter is also required.
Is the High-Pressure Netafim CoolNet Pro Fogger good for spring greenhouse cooling?
Yes, the high-pressure Netafim CoolNet Pro Fogger is perfect for regulating spring and summer greenhouse temperatures. It produces an ultra-fine 65-micron mist that evaporates rapidly, cooling the air and increasing humidity without over-wetting your plants.
Because the droplets flash-evaporate before hitting the benches, it keeps foliage dry, which is critical for preventing fungal diseases in high-humidity environments.
How does the orange pin check valve on the Netafim CoolNet Pro Fogger work?
The built-in orange pin check valve requires high pressure. It opens at 58 PSI and instantly closes when pressure drops to 26 PSI. This provides an instant on/off effect and prevents your overhead lines from draining onto plants.
How high should I hang the Netafim CoolNet Pro Fogger?
For optimal evaporation and humidity control, you should install the CoolNet Fogger 18 to 30 inches above your greenhouse benches, spacing the fogger heads approximately 36 inches apart along your mainline.
What hardware do I need to install the Netafim CoolNet Pro Fogger?
This commercial fogger requires the DripWorks Micro-Sprinkler/Fogger Hanging Assembly. The hanging assembly connects the fogger head directly to your suspended overhead 1/2-inch or 3/4-inch poly mainline tubing.
