DiFluid AirWave - Roast Smoke Eliminator

The NovaCat catalyst is engineered specifically for coffee roasting emissions - it targets the hydrocarbons, VOCs, and carbon monoxide that roasting produces, converting them to CO₂ and water vapour without generating ozone. Third-party lab tests confirm removal rates of 99.4–99.9% across compounds like benzene, toluene, and acetone. In practice, users roasting 250g batches report indoor particulate peaks dropping by roughly 90% compared to roasting without it.

The AirWave is at its best handling sample roasts and smaller batches at light to medium roast levels - the conditions where its 130m³/h airflow and catalyst capacity comfortably keep up. It's rated up to 1kg (220V model), but if you're regularly roasting large batches dark, you're working at the limit of what a compact catalytic unit can do, and a commercial-grade afterburner is the more appropriate tool. We'd rather tell you that now than after you've bought one. For enclosed spaces, DiFluid recommends maintaining proper ventilation alongside the AirWave - think of it as drastically reducing what goes out of your flue, not eliminating the need for one.

A built-in self-cleaning mode clears oil, dust, and chaff buildup — run it every 50kg of roasting to extend the catalyst's lifespan. The magnetic chaff collector catches silverskin and debris before it reaches the internals; pull it out, empty it into the garden, pop it back in. The catalyst module itself is replaceable and recyclable, and insulation keeps the outer surface safe to touch even during long sessions.

Standard filtration (250°C target) covers lighter smoke conditions and smaller roasts while saving energy; Extreme mode steps up for heavier loads. Over-the-air firmware updates via DiFluid Café or CoffeeOS mean the unit improves over time, and it can pair with DiFluid's OmniFlux (sold separately) to automatically adjust airflow in response to your roast in real time.
