QuadBar 4635

QuadBar™ 4635 Limited Space Static Control Ionizer with Air Assist

24 VDC ionizer      

Static Charge Control Ionizer with Air Assist Cartridge Design with Cross-channel Air Delivery

Simco-Ion’s QuadBar™ Ionizer with Air Assist Model 4635 provides effective static charge control in a small format. The Model 4635 offers two air assist cartridge design options. Each utilizes a cross-channel air cartridge built around the emitter points that provides optimal air distribution with minimal field voltage.

  • Air assist cartridge design with cross-channel air delivery
  • Two cartridge design options offers extended cleaning periods (standard with sheath air flow) or faster discharge times (jet with center orifice)
  • Rotatable cartridge design
  • Quadropole configuration with IsoStat technology
  • Compact size
  • Single Crystal Silicon emitter points
  • Alarm output to FMS or process tool controller

Controller Model 4030

Simco-Ion Model 4030 QuadBar Controller is a convenient solution for powering and monitoring up to 16 QuadBars and 2 AeroBar Model 5685 ionizers for optional AeroBar ionization.
