At last a quality affordable floor pump ( pomp) that does it all

Are these tiny compressors capable of seating tubeless tyre's? 

Yes I have solid floor pump and beads lined with soapy water. 

Just to be able to seat tyre's with least amount of effort

 

It wont unfortunately.

[MajG]

are these really loud/noisy? Should I opt for the silent compressors, R1000 more at Addendorff.

 

Will basically be using this for tubeless setups. pump up trailers wheel on the odd occasion and maybe blow water off bikes

You need a compressor that delivers around 1.5 to 2L per second

a 2.35 tyre has a volume of roughly 5.5L. That volume needs to be filled quickly, in roughly 2-3 seconds in order to get the tyre seated. 
so I’d say 100L/minute would be a minimum speC to seat a tyre if the rim is prepped properly. Ideally you’d want about  200 - 300 L/ min compressor

ok then I will need to weigh up the cost of 100l or 200l compressor for convenience OR just keep on pomping my arms like Arno on my floorpump

Those 4x4 compressors will move less air than a standard floor pump - you need something with a tank for DH casing tyres or sketchy conversions, but for a proper trail tubeless setup a floor pump is usually fine.

25l is ok, 50l is better. The direct drive ones are noisy and need maintenance, the oil free ones are expensive but quieter - but for the amount of time it'll spend actually running in a home workshop it won't make that much difference.

If you want a demo I have both kinds at the shop, swing round and I can show you.

I have one of these and it works perfectly well for seating tyres.

At 5:30 in the morning when you're dong a quick top up and the compressor turns on, your're going to wish you went with the "silent"/oil free option. 

I use this one:

Thanks for the offer, I will be in your area thursday - I might pop in to make that noise assessment.

I definitely won't be using it alot, so guess the noise factor shouldn't be too bad. Just want to buy the compressor with good enough flow rate that I won't need to struggle seating DH casing tyres (which is my current issue!!!!!)

So 50l it is

Dont get confused between 50L and 50L/min 

In compressor speak, the 50L means the tank size, not the flow rate. Or 100L is the tank size and not the flow rate. 

Usually any compressor with a tank will be suitable to seat tyres. The little 6L version that Lukelan posted above is fine as it has a tank which will help discharge a sufficient amount of air to seat the tyre. It might not be enough to seat and get to the correct presssure, but this is fine as the compressor will start up and recharge the tank to allow you to inflate the tyre to the desired pressure. 

If you buy a 100L or 200L compressor to just seat tyres, good luck in finding the desired space in your garage to store the thing.

Ya it’s flow rate I’m talking about not tank capacity. 
also there’s piston displacement and free air delivery. 
If the compressor has a feature to discharge all the tanks air then a smaller tank is fine . The first compressor that was pictured, was actually a 12V pump with a small accumulator tank that just smooths air delivery. if a proper compressor is what you’re after then even one with a 20L tank is sufficient provided it can pressurise the tank to about 10bar. The bigger the capacity of the accumulator the lower the pressure you can get away with but 6 bar would be the lower limit 
 

[MajG]

All clear, fully clear to me tht flow rate is the important factor. 

Luckily I do have sufficient space to store the tank. 

 

Helpful responses gents, dankie

I had have no problems seating a tyre with one of these. And I ride Maxxis 2.40" on DD / DH casing rubber. I don't own a compressor and I seat the tyre with a cannister, deflate the tyre to add sealant and then pump it with the trusty floor pump. Works every time.

[MORNE]

Never had an issue seating tyres with a floor pump. Soapy water/cloth, remove valve core, pump to 40psi, wait for the 3 or 4 pops as you go, remove, add sealant, add valve core, pump. Done. Without fail.

something like this ?, 109l/min

 

Yes it works.

 

BUT ... now it comes down to your fittings and tubing ....

 

There is enough pressure, and enough volume in the tank.  The trick is to get it into the tyre quick enough.

 

I ended up cutting off the valve connector, and just pushing the tube directly over the valve stem.

 

 

TIP - set the pressure regulator down to 3 or maximum 3,5 bar.  Thus less chance of bursting a tyre or rim.

 

PS - After many years of use I replaced this compressor with one the new oil-less units .... much more noise .... the compressor delivers less air flow, not an issue for pumping tyres, but soon becomes a pain using compressed air to dry the chain and other components.  My next purchase will be another of these units.

Uhmmm ... 

 

So you use the compressor at some civilised hour.  Job done.  Bike packed for the ride tomorrow ....

 

And the compressor leaks minute amounts of air .... 3:30 the damn thing auto restarts, as you forgot to switch off the plug ....

 

it happens .....

 

 

 

 

oil less does NOT mean silent !!!  My oil less unit makes a crap load more noise than my old compressor ever did.

 

 

 

 

JUST BUY IT    Once you have a compressor with a tank you WILL find so many more uses for it.
