I just watched your video, and as a licensed Union electrician for 30+ yrs. You should have mounted your timer/ contacts off your Air compressor and to the wall. In time with all that vibration from the Compressor motor. The timer can and will shake loose from its seat/base. Nice video and a little complex but works.

Oh there most undoubtedly has to be better ways to do this. My cover mechanically locks the timer in - only reason I've been safe from vibrations. Would still prefer something wall mounted if possible. People are usually shocked when they find out I'm not an electrician 😃

The reason it has a pigtail coming out is it’s a sealed unit. Adds some protection

Good job using the red hat and not the cheapo ones. Can usually find nos on ebay

Excellent instructional video because of you’re attention to detail. I have a much smaller compressor and at the end of the day I drain the tank of air completely and leave the valve open until I need air again. That’s what I thought the “drain daily” label meant. I now have my compressor located remotely so opening and closing that valve everyday has become a pain. Am I correct in assuming this automatic setup will expel enough water so that the residual air left in the tank will be sufficiently dry to prevent sediment and rust build up? I only use my compressor a few days a week . Many thanks !

Works perfect for someone running their compressor once a month OR once an hour

@wurlabyscott 3 года назад

Very clean install but(lol) my one concern, how will the vibration affect the timer.

@doomsdaydiesel 3 года назад

Great point. I forgot to mention - I found a gang box the right dimension that prevents the timer from dislodging. As far as longevity/lifespan, I will certainly update if I have any issues arise from it. The fact everything is solid mounted between motor and reservoir tank kind of blows my mind. There is certainly a LOT of vibration present. My fix, if it became an issue, would be to relocate the timer to the wall.

How has the auto-drain been holding up, and how did you drop the amps down for the low amp timer and 18awg wire?

@doomsdaydiesel Год назад

Knock on wood, it's been flawless so far. The only issue I've seen it all is the condensation can freeze outside since it gets down to negative 20ﾟ here. Just gotta keep an eye on that when it's really cold out.

@iSparkFU Год назад

Good to hear! I'm thinking of doing this. Your video is great! Time for a heated blanket on the tank, eh? For those colder climates. :)

What is the time interval between the blowdown?

@doomsdaydiesel 2 года назад

There isn't one. That's the point of it

@alconk7129 2 года назад

@@doomsdaydiesel so it does that the whole time it’s running?

@simpsonrdlarry4385 2 года назад

Couldn’t you just have plugged it into a wall socket?

@doomsdaydiesel 2 года назад

Those style of timers are always on. So you can set them to drain every 12 hours. But if you're not using the compressor for a week, it's a waste. And if you're painting and needing it to drain every 5 minutes, then that obviously doesn't work either.
