About Upgrading Kit
The differences between K6edge and K6edge Pro are:
K6Pro built in with a compressor only and connect with a outside vacuum pump.
K6Pro has equiped with the latest airbag material which has been proofed work over 100,000 times.
Oil vacuum pump has a better vacuum capacity, which can resist the delay bubbles,that's why we equiped the K6Pro with oil vacuum pump.
To upgrading your old K6edge, what you need are:
Oil vacuum pump x 1
Top plate kit with new airbag x 1
Socket for vacuum pump x 1
Silencer for the built in compressor x 1
Please don't worry about how to install the vacuum pump, we have detailed tutorial video in this page for helping you.
