Kaleido roasters are designed with a built-in smoke extraction system, making them suitable for most home and small-scale roasting scenarios. However, when roasting larger batches or darker profiles, additional ventilation may be necessary to manage smoke effectively. In this guide, we’ll explore when and how to vent your Kaleido roaster for the best results.

When Should You Vent Your Kaleido Roaster?

While the built-in extraction system works well for light to medium roasts, you may need external venting if:

You roast larger batches (e.g., 500g or more on an M10 model).

You prefer darker roasts, which produce more smoke.

You roast in an enclosed space where smoke buildup could be an issue.

Recommended Venting Setup

To enhance smoke extraction, Kaleido Roasters Canada recommends:

An exhaust pipe (flexible, heat-resistant ducting).

An inline duct fan (to improve airflow if needed).

Choosing the Right Duct Size

Kaleido exhaust port diameter for each model:

M1: 25mm (1 inch)

M2 & M6: 32mm (1 ¼ inch)

M10: 45mm (1 ¾ inch)

Inline Duct Fan Recommendation

If your setup requires additional airflow, an inline duct fan can help. A popular option is the: VEVOR 4 Inch Inline Duct Fan

Adjustable speed control for optimal smoke extraction.

Quiet operation, suitable for indoor roasting setups.

Installation Tips

1. Avoid direct connection – Do not attach directly to the roaster’s exhaust port, as this can create back pressure and affect roast quality. Instead, position the fan a few inches away.

2. Use heat-resistant ducting – Ensure your ducting is rated for high temperatures.

3. Keep the duct short & straight – Minimize bends and length to reduce airflow resistance.

4. Vent outdoors if possible – If roasting indoors, venting outside (through a window or wall) is ideal.

Safety Considerations

Ensure proper ventilation to prevent smoke inhalation and maintain a comfortable workspace.

Avoid overloading the built-in system—upgrade ventilation for larger or darker roasts.

Monitor for back pressure, which can impact roast consistency.

Final Thoughts
While Kaleido roasters have an efficient built-in extraction system, adding external venting can significantly improve performance—especially for high-volume or dark roasting. By following these guidelines, you can achieve cleaner, more consistent roasts while keeping your workspace safe and smoke-free.
