If pedicure spa ventilation is required in your area, the Echo LE, Echo SE or Vantage VE may be ordered with a vented-air option. Two (2) vents are located within inches of the pedicure footrest area. When connected to an external HVAC system (not included), toxins and odors are vented outside of the building. Provide a safe and relaxing environment by improving the air quality in your salon.
