Pulse AC Area Static Eliminators: Wide-Area Neutralization on High-Speed Transfer Systems
Pulse AC discharge generates alternating positive and negative corona ions from each emitter pin. Adjustable pulse frequency (1–100Hz) controls ion travel distance, delivering consistent charge neutralization across wide working zones for high-speed substrate transfer. Compared to conventional AC ionizers, it reduces ion recombination, maintaining ion balance ≤ ±10V over 50–1500mm working distance.

Pulse AC discharge physics for extended distances
All emitter pins switch polarity synchronously. Low frequency (1–10Hz) settings extend ion propagation for wide 3D spaces; high frequency (50–100Hz) optimizes neutralization for fast-moving workpieces. Ion recombination loss drops by 32% vs fixed-frequency AC ionizers.

Panasonic ER-X dual-head & air assist configurations
ER-X dual-head units deploy paired discharge heads for broader coverage. Air assist at 0.05MPa boosts ion transport without particle dispersion. Discharge needle contamination rate reduces, extending maintenance interval to 2000 operational hours.
