SUMMARY

This discussion centers on the feasibility of using electrostatic precipitation to enhance air quality in a homemade clean room designed for hard disk head and platter transplants. The user, Mr.A, is constructing a glove box and experimenting with various filters, including DIY HEPA filters and electrostatic precipitation using a modified mosquito killing bat that generates high voltage. Key insights include the confirmation that ionization occurs when the distance between electrodes is minimized, and the importance of maintaining a clean environment through proper chamber design and filtration methods.

PREREQUISITES
  • Understanding of electrostatic principles and ionization
  • Basic knowledge of clean room design and requirements
  • Familiarity with high-voltage circuits and safety precautions
  • Experience with air filtration systems, including HEPA filters
NEXT STEPS
  • Research the design and implementation of electrostatic precipitators in clean rooms
  • Learn about the construction and effectiveness of DIY HEPA filters
  • Explore the principles of ionization and electric fields in gases
  • Investigate best practices for maintaining a clean environment in sensitive electronic repairs
USEFUL FOR

This discussion is beneficial for DIY enthusiasts, electronics repair technicians, and anyone interested in creating a portable clean room for sensitive operations, particularly in data recovery and hard disk maintenance.

Hello every one. Hope you are doing amazing. I am new to the forum and I hope I am putting the post under appropriate thread. Please feel free to guide me through rules if I do mistakes.
I will honor every ones reply over my little project.

I am making a small glove box which is inclined towards doing hard disk head and platter transplants.
My father is into data recovery business and often has a requirement of hard disk head transplants.
We lack a clean portable room in our office and as a B.Sc First Year student, I decided to take a step and device a portable clean environment glove box in which the disk can be kept and transplants can be performed under low particle environment.

The air inside the glove box will be removed with a pump and fed into a chain of filters. I will be experimenting with various kinds of filters ranging from automobile (bike) filters and will also do DIY searches on HEPA filter. I have a bug in my mind to incorporate a electrostatic precipitation somewhere in the chain. The air will be passed through these filters and will be re-fed into the box so that the internal pressure is maintained to what ever it was.

Here is something that I did and a few observations.
I brought a mosquito killing bat which is having a small battery source and a step up circuit which increases the voltage to around 2-3kV. Some forum/website said even close to 8kV.
My multimeter reads around 2kV when the battery inside is partially charged.

I rip opened the racket and connected two copper plates that are used to make pcbs using wires attached to the plats and the terminals on the racket.

I keep the circuit on and try to bring the plates together. When the plates are held around 1cm apart, i hear sizzle sound from them. Is air being ionzed... The air surely gets ionized when the plates are kept as close as 2-3mm since there is di electric breakdown seen (sparks).

The question is? is the air being ionized?
To my little knowledge E=V/D (electric field) ...F=((Q.q)/(d^2)) * 9x10^9...so when d tends to zero E increases and F also increases (since E also = F/C)...so more force between the plates could cause the gas to ionize?

Kindly shower wisdom.

Sincerely
Mr.A

Yes, if there is breakdown between the electrodes then ionisation is occurring. There will also be a characteristic smell of ozone when ionisation occurs.

With today's drives you will be hard pressed to get a sufficiently clean environment. I would make a chamber big enough to work on the drive and store all the tools. It would have long-armed gloves and a window. It would be maintained at a slight positive pressure by dry nitrogen passed in through a filter system.

Access would be through a double air lock. The first chamber would be a closed cleaning area using a dry nitrogen gas jet that would be operated close to atmospheric pressure. The drive would then be passed to an intermediate chamber that could then be evacuated prior to being filled with dry nitrogen. The drive is then passed into the inner clean chamber to be worked on.

All tools and parts would be passed through the cleaning process before being stored in the main chamber.

The drive should never be operated in the clean chamber as any failure would necessitate a full cleaning procedure. Opening the drive prior to placing it in the airlock would also prevent contamination of the clean room.
 
Hello Baluncore,
Thank you for your kind reply. So one can reach bond dissociation enthalpy even at lower potential difference..I was somewhere ESPs require as high has 100kV.. Only the thing is the distance between the plates should be less?
Is my approach correct? I have no measures to prove the ions are formed also no smell particularly is noticed.

I will keep everything in mind that you have mentioned. I appreciate your efforts. The project is too personal and domestic and hence fails to have support of big budget.

Every ones inputs are important and hence I wish that every one can participate in sharing knowledge on this subject.

Personal Thanks!


Mr.A
