KNOKOO FES220 Laser Treatment Smoke Extraction Solution

Laser Treatment Smoke Extraction for Scar Treatment Clinics

KNOKOO FES220 in a Polish clinic: bedside source capture, three-stage filtration and practical day-to-day operation.

Laser scar treatment can generate smoke when tissue is heated or ablated. For clinics carrying out smoke-generating procedures, an extraction solution needs to address airborne particles and odors while fitting around the treatment bed and the practitioner's workflow.

KNOKOO combines adjustable source capture with staged filtration to help clinics manage laser treatment smoke where it is generated. This application example shows how a customer in Poland positioned the FES220 alongside a treatment bed and incorporated extraction into the treatment setup.

The Application: Bedside Extraction in a Polish Clinic

A clinic in Poland uses the KNOKOO FES220 during laser scar treatment. Customer-supplied photographs show the white extraction unit beside the treatment bed, with a flexible arm extending a transparent capture hood toward the working area.

This freestanding arrangement allows the hood to be repositioned as the treatment area changes, without relying on a fixed overhead extraction point. The unit's placement and hose routing can be planned around access to the patient, the laser equipment and the practitioner's working position.

Source Capture: Collecting Smoke Close to the Treatment Area

Effective smoke control starts at the capture hood. The FES220's adjustable extraction arm allows the inlet to be directed toward the smoke source. Its transparent hood helps the practitioner see the treatment area while setting the capture position.

The inlet should be positioned as close as practicable without touching the patient or interfering with treatment. NIOSH guidance recommends keeping the extraction inlet within approximately 5 cm (2 inches) of the smoke-generating site.[1] This is general guidance: hood geometry, airflow and the actual treatment setup still need to be assessed.

Extraction should operate whenever smoke is generated. As the practitioner moves to another treatment area, the hood should be adjusted to maintain capture and avoid drawing smoke across the practitioner's breathing zone. General room ventilation remains part of the overall control arrangement.

Three-Stage Filtration: Separate Functions for Particles and Odors

The supplied FES220 product information specifies a pre-filter, an H13 HEPA filter and an activated carbon filter. Each stage serves a different purpose.

StageFunctionOperational benefit
Pre-filterIntercepts larger particles and debrisReduces loading on downstream filters and supports routine maintenance
H13 HEPA filterCaptures fine particles carried into the filtration systemProvides the fine-particle filtration stage
Activated carbon filterAdsorbs suitable gas-phase compoundsSupports odor management and treatment of selected gaseous contaminants

Particle filtration and gas adsorption must be considered separately. HEPA filters capture particles; activated carbon addresses compounds that can be adsorbed by the selected media. Adsorption performance depends on the compound, concentration, humidity, contact time and remaining media capacity. Reduced odor alone does not establish that all airborne contaminants have been adequately controlled.

Compact Equipment for a Bedside Setup

The FES220 uses a 220 W brushless motor and has a stated airflow of 400 m³/h. Its 400 × 310 × 510 mm body, castors and digital control panel support a movable, independently operated bedside arrangement.

The flexible arm helps adapt the capture position to the procedure. Actual airflow and capture performance depend on the installed hood, hose routing, filter loading and system sealing. Motor power and stated airflow should therefore be assessed alongside the complete extraction setup.

Customer Feedback from the Treatment Room

After putting the unit into use, the customer shared a treatment-room photograph and sent KNOKOO the following messages:

"Thank You"
"It works amazing !!!"

This direct feedback reflects the customer's positive experience with the equipment in use. Together with the installation photographs, it provides a practical example of FES220 deployment during laser scar treatment. No quantitative air-quality measurements were supplied for this case.

Maintenance That Supports Consistent Operation

  • Before treatment, check the hood, hose connections, filter installation and seals. Keep hose routing clear of walkways and avoid unnecessary bends or obstructions. Confirm that smoke is being drawn toward the inlet during the procedure.
  • Replace the pre-filter according to its loading and the equipment instructions. If extraction weakens, inspect the hose and filters for restrictions. If odors return, assess the condition and remaining capacity of the activated carbon stage; normal airflow does not demonstrate that the carbon is still effective.
  • Components exposed to laser treatment smoke should be handled under the clinic's infection-control procedures and the applicable equipment instructions.
  • For indoor recirculation, confirm that the selected filtration configuration is suitable for the contaminants involved. Maintain the required room ventilation, personal protection and laser safety measures.

Discuss Your Clinic's Extraction Requirements with KNOKOO

KNOKOO can help match the extraction unit, capture hood and filter configuration to your working conditions. Share your laser type, smoke-generating procedure, daily treatment workload, available bedside space and ventilation arrangement with our team.

Technical note:

Specifications are based on the supplied product information. The stated airflow is not a measured capture rate at the hood. The supplied materials list both H13 and "99.97% at 0.3 µm"; without the corresponding test reports, these are not treated as equivalent or as evidence of whole-system removal efficiency. This application case does not establish medical-device registration or clinical efficacy.
