ORIGINAL DYSON Airstrait Straightener (serial number & instructions manual)

Dyson Hyperdymium motor A 13-blade impeller spins up to 106,000rpm, propelling 11.9 liters of air through the machine per second. This generates 3.6kPa of air pressure, powerful enough to straighten hair as it dries. Style from wet: Three pre-set temperatures - 175°F, 230°F and 285°F. Refresh from dry: Style at 250°F, 285°F or use the optional Boost mode for maximum shine. Intuitive airflow when you need it. Your machine senses when hair is between the arms and automatically drops to low airflow when it's not - for quieter, more efficient styling. LCD screen: High-definition color display shows airflow and temperature settings, for easy reference when styling. Lock feature: Slide the button to lock and unlock the arms of your machine. Use with the arms locked to gently pre-dry hair and create volume from the roots. Auto-pause: After three seconds of inactivity your machine will automatically pause to save energy. Simply move the machine to restart the airflow.
