NATIONAL BH-662 Record Cleaner With Static Eraser

Double Cleaning Method: Brushing And Suction
The Extremely Fine Rotary Brush With 0.05 Mm Bristles Fits Into The Grooves Of The Record To Brush Out Stubborn Dust. It Then Rotates At High Speed (3,000 Revolutions Per Minute) While Suctioning The Dust Into The Dust Box.
Principle Of Static Electricity Removal
By Using A Step-Up Circuit, High Voltage Is Applied To The Discharge Electrode, Creating A Corona Discharge That Ionizes The Air Molecules Into Positive And Negative Ions. Same-Polarity Charges On The Record Are Repelled, While Opposite Charges Are Attracted. The Static Electricity On The Record Is Neutralized By These Ions. The Static Electricity On The Record Surface Is Either Neutralized Or Transferred To The Reverse Side.
