Netafim CoolNet Pro 4-Way Fogger Head Assembly with CNL - 8.1gph - Purple Pin - 60psi

4-Way Fine Fog Head for Greenhouse Cooling & Humidity Control

Greenhouse cooling and humidification depend on droplets fine enough to evaporate before they land on the crop, and a fogger that drains or drips between cycles wets the canopy instead of cooling the air around it. Netafim's CoolNet Pro 4-way fogger head assembly outputs 8.1gph split across four directions for even fog coverage, and its CNL feature holds a consistent flow rate while its integrated check valve stops the line from draining after shutoff.

Rated at 60psi with purple pin color coding, this head is built for dedicated greenhouse fog cooling and humidity systems rather than general overhead irrigation.

Key Features & Benefits

• 4-way fog output — spreads 8.1gph across four directions for even fog distribution instead of a single concentrated stream.
• CNL pressure-compensating flow — holds fog output steady across a range of line pressures for consistent coverage.
• Integrated check valve — stops the line from draining and dripping between fog cycles.
• 60psi rated operation — matched to dedicated greenhouse fog cooling and humidification systems.
• Purple pin color coding — identifies the flow rate at a glance in systems running multiple fogger ratings.

Who Should Use This

This fogger head fits greenhouse operators running dedicated cooling or humidity control systems who need fine, even fog coverage without drip or drainage between cycles.

About Netafim

Netafim is an Israeli irrigation company credited with commercializing drip irrigation, and its CoolNet Pro line applies that same pressure-compensating and anti-drain (CNL) technology to greenhouse fog cooling systems.

Frequently Asked Questions

What does CNL mean on this fogger head

CNL stands for Compensating Non-Leakage, combining a pressure-compensating nozzle with an integrated check valve. That keeps fog output consistent across a range of line pressures while stopping post-cycle drainage that would otherwise drip onto the canopy.

What is this fogger head used for

It's built for greenhouse cooling and humidification systems, where fine fog needs to evaporate into the air rather than wet the crop. The 4-way output spreads that fog evenly across a wider coverage area than a single-direction head.

How much pressure does this fogger need to run correctly

It's rated for 60psi, which is typical for dedicated greenhouse fog cooling systems. Running well below this pressure can reduce droplet fineness and coverage evenness.

Why is drainage between cycles a problem for fog cooling

If a line keeps draining after shutoff, water drips out of the low points instead of evaporating as fine fog, which wets the canopy rather than cooling the surrounding air. The integrated check valve in the CNL feature stops that drainage.
