Visual airflow checks
Use around HVAC vents, duct joints, cabinets and draught paths to make air movement visible.


Selected kit
The HVAC Smoke Pen Kit is a compact smoke-source kit for maintenance teams and practical users who need to make air movement visible around ductwork, vents, cabinets, grilles and other suspected draught or leakage points. The current kit specification is one smoke pen with six replacement wick cores. Use it as a qualitative visual aid for tracing flow direction and choosing the next inspection step, not as a calibrated measurement instrument, formal compliance test or proof that a space is sealed.

Buying guide
At a UK workshop or packing-bench maintenance job, you need to see which way air is moving around a vent, duct joint or cabinet before deciding what to inspect next. An HVAC smoke pen can make that movement visible, but only if you treat it as a qualitative visual aid rather than a measuring instrument.

Use cases
A facilities operator is checking airflow around vents and duct joints at a small workshop, office or service premises in the UK. This guide helps decide whether a compact smoke pen is suitable before buying.
