Product Details

Product Information

This professional-grade HVAC-compatible scent diffuser is engineered for large commercial and residential spaces up to 15,000 sq. ft. With a generous 2500 ml fragrance oil capacity (oil not included), the HVAC150 offers powerful cold-air diffusion using waterless and heat-free technology.

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.
