- Typical airflow rate
- Units in this class typically offer variable airflow, commonly ranging from 100 to 700 litres per minute.
- Filtration stages
- Most surgical smoke evacuators feature multi-stage filtration, including pre-filters, activated carbon, and HEPA filters for effective particulate and odour removal.
- Noise level
- For this type of equipment, noise levels are typically designed to be low, often below 60 dB(A) at maximum power, to minimise disruption in clinical environments.
- Power supply
- Commonly operates on standard single-phase mains power, typically 220-240V, 50Hz for the UK market.
- Footprint
- Units are generally compact and mobile, designed to fit alongside operating tables or under benches, with a typical footprint of around 30-50 cm per side.
- Filter life indicator
- Many models incorporate a filter life indicator or alarm to signal when filter replacement is required.
