Active purification of surgical smoke – The IES 300 system from Erbe
The IES 300 is a high-performance surgical smoke extraction system developed by Erbe Elektromedizin to improve safety, hygiene and visual comfort in operating theatres. It is designed to effectively remove fumes, vapours and aerosols produced during the use of thermal instruments such as electric scalpels or surgical lasers. These fumes contain not only water and fine particles, but also organic gases that are sometimes toxic, malodorous compounds and potentially infectious bioaerosols.
The IES 300 acts as a protective barrier against these nuisances. It extracts polluted air directly at the source — using a cannula, funnel or hose positioned close to the operating site — then treats it via a multi-layer filtration system before returning it to the working environment in a purified state. It combines a ULPA (Ultra Low Penetration Air) filter capable of retaining virus-sized particles with a three-stage gas filter to capture volatile organic compounds and neutralise unpleasant odours.
Suction is provided by an electronically controlled brushless fan, ensuring constant power, quiet operation (<52 dB(A)), and a long service life without heavy maintenance. The user can adjust the suction power (20 to 100%), the pre-suction mode (up to 30%), and the post-suction time (up to 100 seconds or continuous mode). These settings are easily adjusted via a front control panel with an intuitive LED display.
The IES 300 can be activated in three ways:
- Manually, by simply pressing the "Active" button on the front panel.
- Automatically, via an integrated current sensor that detects when the surgical device is switched on.
- Remotely, via an external control or a foot pedal connected to the rear of the unit.
To ensure safety and reliability, the IES 300 has an automatic error detection system with coded messages (E01 to E07) and filter status check. A 15-LED bar indicates the filter contamination level in real time. When the filter reaches the end of its service life, a red indicator light and an audible alarm alert the user. If the filter is missing or incorrectly inserted, the device prevents activation, thus avoiding ineffective or dangerous suction.
The IES 300 complies with the most stringent international medical standards (IEC 60601-1, EN 46001, ISO 9001) and is classified as a Class I, Type CF medical device. Its modular and robust design allows for easy integration into any operating environment, whether in general, gynaecological, ENT or cosmetic surgery.
