Thanks everyone for your suggestions and comments, it seems that the issue has been resolved. I've made copper line from the pump to the tank with manual release valve: Manual valve, picture And it worked great! Then I replaced it by the electric solenoid valve + delay timer from American...

Check out the engine HP on an engine driven compressor with the delivery specs of your compressor and see what it is. It's very approximate calculation. There is no gas powered air compressors with 60 gal tank. Considering only CFM@psi, in my case it is ~16cfm@90psi. There are multiple engines...

At this time I can't make other tests because I'm out of capacitors :) Going to order a new one. I honestly don't think that higher voltage capacitor will help because the issue is that the voltage even lower that required. But since I have to order new capacitors anyway, I can order 370V...

mm08822, there were few minutes of delay between my tests. For the last one or two tests (when only plastic tubing was disconnected) I couldn't start my generator for 3 minutes, it didn't react on key, could've been some thermal protection after previous 4 start \ stop tests. But then it...

I don't remember exact part number, but the PS is actually not original, but replacement part that I've bought here: Powermate Vx 034-0184RP Pressure Switch I clearly remember it's 125-155 or 120-150psi. I bought it as exact replacement for the original one that I accidentally broke during wires...

I have a sandblasting cabinet. Nothing crazy, I'm just a weekend warrior, but that's why I want 5hp continuous flow. Speaking about the timer, I thought it can be eliminated, because the solenoid can be connected to the start cap. In this case, it's disconnected as soon as the motor will start...

Hi Everyone! The compressor is Central Pneumatic 60 Gal from Harbor Freight. Link to the compressor on HF site The reason why I bought that 12kW generator is just because I thought it will be enough to start the compressor (at that time I didn't know about x7 amperage at start up). I also...

Well I don't really know internalls of the pump and where is the bottle neck. When I did my tests where the capacitor had been blown, I had an empty tank and opened tank's valve.. So it's a 'first run' test, not even that one when the compressor is almost full and just tries to refill..

Great idea, will do, thank you.

Thank you, I'll research your ideas with the unloader. But honestly, I'm thinking about soft starters. As they are actively used in HVAC, I'm trying to understand if it's applicable to my situation. For example (don't want to mention exact brands that I googled): Before: soft starter...

1. All it has is the standard pressure switch. As I understand, centrifugal switch on the motor is the devise that supposed to disconnect start capacitor. I've never seen before any devices that would analyze if the power should be cut because the motor hasn't reached target rpm during start up...

Good Day! I have DuroMax XP12000EH generator that's capable produce 12kW. It has 240V receptacle and 50Amp breaker. My generator front panel picture I thought it will be enough to power 60 gallon air compressor, so I bought HarborFreight one with the Century 5hp motor. Motor plate picture...
