Surgical procedures that use electrosurgical tools, lasers, or cautery devices produce hazardous plumes of surgical smoke. This smoke contains toxic chemicals, bioaerosols, and unpleasant odors that can harm operating room personnel. A well-designed air switching system for surgical smoke evacuators ensures safe, hands-free control of smoke removal during procedures, improving both visibility and air quality.

Why Surgical Smoke Must Be Removed
Surgical smoke contains carcinogenic compounds, viruses, and fine particulate matter. Continuous exposure to these airborne hazards increases health risks for surgeons, nurses, and support staff. Modern smoke evacuation systems help remove contaminants in real time, but they are only effective when activated at the right moment. That is where a responsive air switching system becomes essential.
What Is an Air Switching System for Surgical Smoke Evacuators?
Presair’s air switching system for surgical smoke evacuators integrates a pneumatic foot pedal and an air-activated switch. This setup provides hands-free, sterile control of the smoke evacuation process. It eliminates the need for direct electrical contact and allows seamless activation and deactivation during procedures.
How the Air Switching System Works
The system includes two primary components that work together:
Pneumatic Foot Pedal
The surgeon activates the foot pedal to generate a controlled puff of air. This pneumatic signal travels through flexible tubing to the air switch. Because the pedal is floor-operated, it allows surgeons to maintain a sterile field while controlling the smoke evacuator without using their hands.

Air Switch with Internal Microswitch
The puff of air from the foot pedal triggers the internal microswitch inside the air switch housing. This microswitch sends a signal to the smoke evacuator to begin suction. When the foot pedal is released, the air pressure drops, deactivating the switch and stopping suction immediately.
This design provides instant, on-demand control of smoke evacuation without requiring electrical wiring near the surgical field.
