The Span America-8310 Control Unit is a high-efficiency system engineered to power bariatric air therapy surfaces. It manages skin microclimate through high-volume low air loss (LAL) while supporting heavy weight loads without bottoming out. Designed for clinical safety, the unit features a 30-minute "Auto Firm" mode for stable transfers and a "Lockout" function to prevent accidental setting changes. Its streamlined, lightweight build operates quietly on less than 15 watts, reducing heat and noise in the patient environment.
