Frequent Asked Questions:

1. What type of gas we can use?

PFI suggests to use 134A or green gas for safety purpose, using other type of strong pressure gas may damage the structure of the product.

2. Do I need to fully inject gas before operation?

The more gas you inject, the higher the internal pressure so user can try different amount of gas to get the best result for their own purpose.  However, one small injection is enough for demonstrating the grenade operation.

3. How many BB can be put inside the gas can?

We have tried to put 8 BBs and still get good performance, putting too many BBs may not be ejected during explosion.

4. Can I use other powder?

PFI suggests user to use only PFI's powder disc, using other type of powder or liquid may damage the internal structure.

5. Can I adjust the time to explosion?

Yes, we have a timer structure for user to adjust the time to explosion, just simply adjust the mounting screws to fine tune the timing.

6. Can I use PFI-828 under water?

Yes, PFI-828 is water proof, you can set your grenade and put it under water.  The explosion is even stronger than in open air.

7. Can I put some power into the gas can for explosion?

Yes, putting some power inside the gas can before injecting gas into it could experience a much stronger smoke effect.
