These Plants Don’t Need Dirt, Just an Atomizing Spray Nozzle

Recently I was working with a company who grows plants using a method I’ve never heard of before, aeroponics. See I grew up on a farm, so I’m used to the old fashion way to grow crops! Dirt, water and sunlight, or as my grandpa would call them “The three pillars of life as we know it”.

So I had to do some research into aeroponics so I could understand if we could help him. It turns out aeroponics does not use a dirt medium, they relay on a very fine mist to provide the nutrients the plant needs to grow.  But its very important that the mist have droplet sizes of less than 50 microns, or the roots will not be able to absorb it.

At that point I knew EXAIR’s Atomizing Spray Nozzles were the right direction!

We ended up going with the AW8010SS Internal mix wide angle round pattern. And after playing with them the customer ran the nozzles at 5 PSIG air pressure and 10 PSI of  liquid pressure. running the nozzle every 10-15 mins kept the room at the perfect humidity for the plants they are growing.

They are planning to install up to 20 of the AW8010SS Internal mix wide angle round pattern in each section of their facility once they build their building!

Air Atomizing Spray Nozzles from EXAIR

EXAIR’s Atomizing Spray Nozzles are used in a variety of applications where atomization of a fluid is necessary. They combine a liquid source and compressed air to atomize the liquid into a very fine mist. With a wide variety of spray patterns and ability to customize the maximum flowrate, there’s an Atomizing Nozzle available for just about any application.

I’d like to take a moment to highlight two particular spray patterns that EXAIR has available: Internal Mix Deflected Flat Fan and Internal Mix 360° Hollow Circular. With both of these particular spray patterns an “internal mix”, the mixing of the compressed air and the liquid will occur inside of the nozzle.

The Model AD1010SS Internal Mix Deflected Flat Fan Pattern is a ¼ NPT Type 303 stainless steel nozzle designed for applications where mounting space is at a premium. The spray pattern deflects at a right angle to the nozzle’s orientation, allowing the spray to be placed precisely where it’s needed in close quarters. An ideal application for this particular spray pattern is coating the inside of an in enclosure or duct work.

The Internal Mix 360° Hollow Circular Pattern is available in two sizes: ¼ NPT and ½ NPT. These nozzles provide a large 360° circular pattern that works well in applications where a smooth, even coating is needed on the ID of pipe or duct work. Due to the large coverage area (up to 13’ in diameter for Model AT5010SS) they’re also ideal for applications including dust suppression, humidification, and cooling.

Both of these styles of spray patterns are available with or without the No-Drip feature. EXAIR’s patented No Drip Atomizing Nozzles work just the same way as the standard ones, but have the added benefit of positively stopping the liquid flow when compressed air supply is shut off. If your application cannot accept post spray liquid flow dripping onto the product or process, these nozzles are able to accommodate up to 180 cycles per minute with a required 30 PSIG minimum air pressure.

With all sizes and spray patterns available from stock with our Unconditional 30-Day Guarantee there’s no excuse to not give one a try!
