Plumbing my new 8 HP Honda driven compressor

by Joe Grippi
(Englewood, Florida)

I have a new 8 HP Honda driven 19 CFM air compressor that will be mounted at the front end of my f350 Ford truck bed, which will service two 15 gallon horizontal wing tanks mounted over my wheel wells, and also service another 30 gallon vertical tank positioned on my wash rig about 12 feet from the compressor itself.......I would like to know the best way maximize this volume via the plumbing between these air units......

I should mention, that there will be times that the truck is remote from the trailer, where I would have both wing tanks operating at 30 gallons, other times, with trailer, I would want all connected together to work with the full 60 gallons of storage......Any help in sizing these interconnecting lines and valves would be greatly appreciated.....Joe Grippi

Hi Joe:

It were me, I'd go with 3/4" good quality rubber / vinyl hose. Remember, hose is measured on the I.D.

I don't know the geometry of the layout, other than as you have described, but I have no doubt that with a selection of couplers, connectors and ball valves, you can rig your system to make your tanks connected or isolated as and when required, without losing air as you do so, and do the reconfiguration in minutes.

Talk to your local compressed air valves and cylinders supplier. They will be able to help out with the parts and the design.

Cheers,

Bill

Thank you Bill for your help in this, especially your quick response I appreciate it greatly......My tank stands for the pickup bed wing tanks are ready and waiting, and I am anxious to get to the plumbing....Please may I ask further,with a 1 1/2 inch outlet from the compressor, should I manifold it at the same dimension, then reduce to the 3/4 inch to the air units, or should I carry this large output volume and reduce later in the configuration?.....Please keep in mind, from the compressor unit to the two wing tanks is only a couple feet of bed length, with the other 30 gallon vertical tank about 10 to 12 feet aft of this.....Finally, should I connect with the coupler type that does not reduce the internal hose volume, or am I okay with the usual coupling types?......Surly appreciate your expertise in this......Thanks again.....Joe......

You can't go wrong using the same dimension for plumbing as the outlet of the compressor discharge.

A 1 1/2" line is huge, and will flow massive amounts of compressed air.

The only way to be sure is is to know, when you are using the compressed air, how much air will your applications need in CFM and Pressure.

The higher those numbers, the larger the lines required.

On the other hand, if the air tool has a 1/2" inlet for air supply, then, in theory, and depending on how far the air has to travel, you should be able to supply that tool with a 1/2" ID air line, yes?

You can't go wrong going with big lines, except where it costs you more money to no real use.

I would always opt for fittings that have full line internal dimensions to help reduce line loss.

Cheers,

Bill
