A turbo-pump diffuser for larger spaces
The Scent Pro is a waterless cold-air diffuser built for medium to large spaces where even distribution matters. A turbo pump drives the output, and Bluetooth handles scheduling and intensity across three settings.
For businesses covering up to 4000m³
Stated coverage reaches up to 4000m³, which suits showrooms, clinics, gyms and larger retail floors. It measures 295 mm by 113 mm by 230 mm and comes in black or white.
How it runs
Waterless cold-air diffusion, so there is no heat and no dilution. Fill the bottle, set your intensity and schedule, and leave it. Give any new setup a day before you judge the strength, as scent builds in a room over the first few hours.
Questions & Answers
Have more questions? Don't hesitate to email us:
What size space is it designed for?
This is our large-format scenting range — built for open-plan homes, offices, retail spaces, gyms and hospitality venues. The exact coverage for this model is listed in the specifications on this page.
How does it disperse fragrance?
Cold-air diffusion. The unit converts fragrance oil into an ultra-fine, dry mist — no water, no heat — and distributes it evenly through the space, so the scent stays consistent rather than fading in and out.
Is it difficult to set up?
No — setup is straightforward and each unit ships with clear instructions. For commercial installations, our team is happy to advise on placement, scheduling and intensity. Reach out at hello@ascentcollection.com.au.
Which oils should I use?
Ascent Collection fragrance oils — they're formulated to the correct viscosity for consistent scenting, reliable performance and long-term durability. How quickly you'll go through a bottle depends on your intensity setting and operating hours.
What warranty and support do I get?
All Ascent Collection diffusers are covered by a 1-year manufacturer's warranty, backed by our Australian, family-run support team. If anything isn't right, we'll sort it.
