Desco 50620 ion python controller kit (B3)
Includes: controller, Ion Python, foot switch, 120VAC NIST
* Balance adjustable 20 voltage offset
Keeps air free of contaminants
Can be activated with foot pedal
* Adjustable 30 PSI to 100 PSI air pressure
Adjustable to meet requirements of the application
* < 1 sec discharge time at 6"
* Low Ozone Emissions tests well below the OSHA limit of 0.05 ppm ozone
NOTE: Air nozzles are recommended for intermittent applications. They require filtered, dry, non-combustible gases, such as compressed shop air or nitrogen. If using nitrogen, contact the factory for modifications and adjustments needed.
Necessary non-conductors in the environment cannot lose their electrostatic charge by attachment to ground. Ionization systems provide neutralization of charges on these necessary non-conductive items (circuit board materials and some device packages are examples of necessary non-conductors). Assessment of the ESD hazard created by electrostatic charges on the necessary nonconductors in the work place is required to ensure that appropriate actions are implemented, commensurate with risk to ESDS [ESD sensitive] items . (ANSI/ESDS20.20-2007 Foreword)
The primary method of static charge control is direct connection to ground for conductors, static dissipative materials, and personnel. A complete static control program must also deal with isolated conductors that cannot be grounded, insulating materials (e.g., most common plastics), and moving personnel who cannot use wrist or heel straps or ESD control flooring and footwear. Air ionization is not a replacement for grounding methods. It is one component of a complete static control program. Ionizers are used when it is not possible to properly ground everything and as backup to other static control methods. In clean rooms, air ionization may be one of the few methods of static control available. (ESD Handbook TR20.20 Ionization, section 5.3.6.1)
All ionization devices will require periodic maintenance for proper operation. Maintenance intervals for ionizers vary widely depending on the type of ionization equipment and use environment. Critical clean room uses will generally require more frequent attention. It is important to set-up a routine schedule for ionizer service. Routine service is typically required to meet quality audit requirements. (ESD Handbook TR 20.20 section 5.3.6.7 Maintenance / Cleaning)
