Product Details

Product Information

HVAC150 can be controlled through Bluetooth via a smartphone application. Just download the application on your phone, connect to the diffuser, and set your program/intensity in a matter of seconds.

The air pump on this diffuser is designed to last about 10,000 hours or approximately five years at average work schedule settings.

The initial investment for this diffuser can be recuperated by using high-end essential oils designed to work with cold-air diffusers, it’s way more economical compared to candles or disposable aroma plug-ins.

Fully programmable 24/7, with up to five programs per day and custom intensity settings. This model can easily be connected to an HVAC system or operate as a standalone unit in an open space.

A step-by-step how-to guide about connecting the Mobile App to control the scent machine.

Connecting to the HVAC

Experience outstanding fragrance scent delivered through your central heating and cooling system. Each HVAC scent diffuser comes with a metal push-in fitting that screws into the machine and a plastic tube that connects the diffuser to the HVAC air duct.

Step 1

In order for the aroma mist to carry through the air duct, the AC must be operating or the blower fan must be turned on. If the AC (or fan) is off, the aroma mist will stay in the air duct and won’t reach the intended space. If the diffuser is operating for a prolonged period of time with the AC fan being off there will be unwanted scent buildup in air ducts and could cause diffuser or air handler damage.

Step 2

HVAC setup typically requires intensity levels 10% to 15% higher compared to standalone diffuser setup. Air duct passage creates an additional volume of space through which the aroma must travel and some capacity is lost due to the extended volume of space. With a standalone setup, the aroma covers a smaller volume of space and has a slower transit time.

Step 3

Installing the air diffuser requires adequate space to accommodate your aroma diffuser and must be close to the air ducts. The ideal placement of the diffuser tube opening is after the air handler and before the first air register (please refer to the diagram above). Please ensure the air duct opening is further away from the air handler body to prevent possible interference.

Step 4

The plastic tube that connects the diffuser with the air duct should be kept as short as possible and at the near-vertical pitch. Avoid ‘sagging’ formations in the tube as this could cause oil accumulation in the lower part of the tube and possibly damage your diffuser.

Step 5

The diffuser plastic tube entering the air duct should be approximately three to four inches inside the duct and pitched at about 10% downward angle just to ease the aroma flow.

Step 6

Ensure proper insulation of the opening by using aluminum tape and secure the plastic tube to one of the hard areas to minimize any tube movement.

Step 7

The placement of the diffuser should be in a dry, clean, moist free environment
nearby a proper 110V power outlet.

HVAC150 Unboxing & Oil Change

People often ask us "How long will my bottle of oil last?"

Fragrance oil consumption varies based on diffuser model, intensity level, and usage. As a guideline, at medium intensity, operating seven days a week from 8:00AM to 8:00PM, consumption per month is roughly: HVAC10: 200ml, HVAC30: 500ml, HVAC150: 1000ml. Actual usage may differ based on settings. Read more FAQs here.

Amazing machine

Bought this diffuser for our office building which is around 10,000 sq feet. This machine does a great job, I like the way it is scenting our lobby and hallways of the building. Good Job team!

L50HVAC Diffuser

I like this device, I donâ€™t have it hooked up to my air system so it just sits in the corner and does well.

I received my Diffuser today

I received my Diffuser today and I can say it came pretty fast, Im impressed about the quality of the machine, I called customer service and they was very helpful in helping me set up the phone App, and blue tooth they also assisted me in setting up the machine, I havn't decided on what oil fragrance I want to go with but they sent me a sample pack with my order so I will be ordering my oil soon. I can say the process from ordering the machine to setting it up was a breeze, and I can't say enough about the customer service the lady I spoke to was so caring patient and helpful, So far I'm sure I made the right choice thank you for taking your time and walking me through the whole process.

Works great as a standalone for home use

I initially purchased this product to use with the HVAC system, but quickly realized it is not the best employment due to concerns about the extreme temperatures in the attic. So, I reluctantly employed it as a standalone in my 2-story, 4,000sqft home which surprisingly produced amazing results. I placed the system in a corner in my living room, using the lowest intensity settings. Bottom line, this product checks the blocks in size, form, fit, and function. No regrets after almost a month of use.

A downside to this product is that it has a loud built-in fan, however, this is a tradeoff I am willing to accept given this is a commercial grade equipment employed for home use. Another downside is that the system lacks contemporary enhancing technology such as bluetooth, apps, etc.

Still, this is a great product. Get yours!

Another fantastic product

I can't say enough about this company. I have bought their Car atomizer x 2, 2 of the C5 1000 square foot atomizer, 1 x M30 atomizer, 2 x L50 atomizer and now the L150. Fantastic products work great, easy to use.

Love them all,

Chris J
