How much vacuum does the specrum pull?

[ADAM DUTHIE]

Frank,

I am surprised that you do not yet understand the meaning of Dry Vacuum as it pertains to PRISM windshield repair technology, which is used by both the Spectrum and Maxim. It has already been discussed in previous threads, and we all know that you read this forum frequently enough.

Of course you want to remove water (moisture) from a break, that is a given but the dry-vacuum as it pertains to windshield repair is the process of removing air from the break prior to exposing the resin. This allows an air to air exchange during the vacuum process, which is more efficient than pulling air bubbles through resin.

The benefits of PRISM technology is that the resin fills the break quicker and the air is removed from the break faster; two key components in a complete repair. Additionally, because of the vacuum and pressure process using PRISM technology, many breaks can be repaired that are too complex for other systems, meaning that with the Spectrum and Maxim, you can completely repair some breaks that would be unrepairable with lesser systems.

I think that we can agree, without any scientific basis at this point, that it probably is easier for air to not have to travel through any liquid (resin in our situation). Under normal circumstances there simply would be less resistance.

But I have also too many times silly sales points being used where the time element has been mentioned as if it were of the greatest importance. It is not, but that is just my opinion. In all fairness...I don't care for the time needed. Its is soooooo American to rant about the benefit to be gaining a few seconds per cycle, reducing the total process with a few minutes per repair, as if that would make a huge difference and anyone be doing one or two more repairs per day.
I am happy to have ''my air'' to be travelling through the resin while I have my injectors under vacuum. In the mean time I will be busy with the work order or prepare my next repair (or be busy with any other injector on another windshield).
Time is certainly not the most valued component when it comes to repairing rock damaged glass.
What does matter instead is the end result and how it will look in five or more years after you have performed the job. The system that is being used to deliver a proper repair is not all that much relevant.
