joining 2 compressors

I know there's loads of threads regarding this but still need some more info. Is it necessary to have non return valves when joining 2 together?

both compressors will have non return valves fitted between the pumps and the tanks as standard. just put a ball tap between the 2 tanks if there permanently conected or use quick release couplings with a short hose with plugs either end

That method would mean 1 pump could fill both tanks, would it not be better to fit NRV's to tank outlets to prevent possible overworking of pump?

i have a twin pump and motor set up on a large storage tank. either pump can be run seperately to fill the tank or both run at same time if large volume is needed if 2 tanks are used and coupled with a hose all that is required is a ball valve to shut off air between the tanks if just a small amount of air is required

My concern about direct coupling of tanks was for example if you coupled a pair of Aldi compressors and one pump failed to start the other one would exceed duty cycle trying to fill both tanks? an NRV on tank outlets would prevent this.

You pays your money and takes your choice, both methods have pros and cons.

The only time I'd use an NRV is if one compressor could exceed the safe working pressure of the other tank.

So would it be best to fit nrv to both compressors then just for peace of mind

 

[rtbcomp]

If it worries you, then yes.

 

[dai751989]

Aslong as nothing really dangerous is going to happen then I don't mind

 

[rtbcomp]

As long as you don't tamper with the pressure settings or the plumbing between the pump and the tank you'll be fine.

Also another question, where can I get the low toxic air hose for airfed mask as I've heard normal rubber airline is no good

Try Arco, they have branches nationwide.
