Harbor Freight Compressor Regulator isn't regulating?
(Leesburg, FL USA)
Have a cheap H/F compressor rated for 4.5 SCFM @ 90psi, tool is rated 4 SCFM @ 90psi.
With the reg set at 90 and tank pressure reading 120, when I trigger the tool (impact driver) pressure immediately drops to 60 and stays there even after the compressor kicks in at 95psi about 8 seconds later.
Have set the reg to 90 (from 0 as I've read here) while the tool is running and this results in a "wide open" regulator, 120psi when tool is off.
(Same issue with blowgun, just less of a drop)
Will I damage the tool starting it with 120?
Do I have a misunderstanding that a regulator should hold the preset pressure as long as there is that much or more behind it?
Could this be a flow issue from tank to reg? Thanks, Peter. BTW: I don't expect or need the compressor to continuously keep up with the tool.
Peter, good questions and good expectations.
The piece of info that you haven't provided is the demand in CFM of the impact driver. This type of tool is, as is a blow gun, huge compressed air suckers.
Your 4.5 CFM at 90 PSI may not even be enough to keep the driver running for a second or two before the entire line from the tank to the tool is void of air.
And yes, if your demand exceeds the supply in flow, the regulator will drop instantly when you trigger to the tool.
Tell me what the specs on the air tool say in a comment here. I suspect the compressor is far too small in both plumbing, regulator flow capacity, or HP to keep up.
Did I damage a seal or something?

When the compressor runs for about a minute, oil start to ooze out of the hole in the oil cap. It started ever since I put a wooden stick in the oil tank to measure the oil level, and when I touch the bottom of the oil tank, it sort of felt like it poked a hole through something. I did not use very much pressure when I put the stick in the reservoir, but I'm thinking I damaged or put a hole in a gasket or something. If this is what's causing the problem, how can I fix it and what parts do I need. Any help would be appreciated. My email, Despinda@gmail.com
Before I used the stick to measure the oil, the compressor worked fine. If I damaged something can you give me some kind of idea if I have to remove the head and replace something. Any instructions on how to get to the broken part would be greatly appreciated. help! Thank You Doug Espinda
