So you want more blast time but don't want to replace your tank with a bigger one. Why not just add a second tank? A second tank can be added to your system easily with a couple of fittings and some air line.
Choosing a Tank
Before you purchase a tank to add to your system, there are a few things that you need to consider.
- How much air capacity am I adding to the kit?
- Is the compressor strong enough for the increased capacity?
- Will the increased fill-time be a problem?
If your system currently has one compressor, there's a good chance it is rated for a tank size up to 5-gallons. You can check your compressor model to determine the max tank size for the unit. In general, most Viair compressors are good up to a 5-gallon capacity. If you exceed 5-gallons, a second compressor is recommended.
If you have a 2-gallon tank and want to add another, you can usually do so without adding another compressor. If you were trying to add a 5-gallon tank instead, a second compressor is necessary to make this work properly.
