Road compressor

[AKA]

Hi all, I’m looking into buying a road compressor for harvest to keep balers and combine clean. How big do I need to go, I’ve seen 100cfm and 140 cfm for sale Is the 100cfm big enough?
any advice appreciated

As big as you can find bigger better …

Minimum of a 2 tool one.

What is classed as a big one 140?
Not wanting to spend a fortune, can get 100cfm for around £3500 but a 140cfm is about £5000.

A 100 CFM will do you job find

We use 260 cfm but not working flat out ..a small one around 100 cfm will overheat easily if used on full flow for long in my experience

Just sold a 450cfm that would clean it from 2 fields away

140cfm is a good all round size I find. It’s small enough to tow easy with a car or van if needed but still has enough volume to do a good job at a bit of entry level shot blasting if it takes your fancy. There will be plenty for sale at the next euro auctions sale a Leeds and could be had for between £2k to£3k for something in good fettle

Thinking there must be something g wrong with our smaller 130 cfm then…after ten or fifteen minutes flat out blowing machines it overheats…always had done and all coolers /filters are clean ,oil clean/changed and the filter in the compressor itselfcan overheat the 260 if ran for half an hour or so blowing say two combines

The pipe/lance is too big bore and theres no back pressure

 

[davidroberts30]

A 100cfm compressor does 100cfm at 8 bar
On a lance there's no back pressure so it's working 300% hence heat

Flatten the end of the pipe so the compressor not full bore

140 would be ideal. Are you wanting to blow 2 machines off at once?

You can get proper, pressure washer style lances, which would be better than a piece of pipe with the end hammered down and a gate valve for a tap. Get miles of 2 inch hose. Also get an adapter so you can use a 1/4 inch workshop hose and tools. The big hoses are great, but you'll want to get in with smaller blow guns. Also the side outlet radiator cleaners are really handy and you might as well get the tool for blowing up and inflating tyres, even an inch drive impact gun.

Full face 3M face masks, ear defenders and thick gloves.

You'll use it way more than you think, just make use it's not blowing oil everywhere

A 140cfm & a 260 CFM for you job a 100CFM would be fine

Thanks for that bit of wisdom. Never thought about it like that. I've put a new rad in our 185 and still over heats. Using open lance
