Title: Bought an Air booster
Post by: DavidS on October 21, 2017, 04:48:31 pm
Seen a deal on an air booster so I bought it.. might be to small so I will try it and see if it will work (pretty sure it will). For $60 I cant complain.

2 questions.. in all the parts that came with it...a little air reservoir what would it be for? I know this stuff was used for a different application so I would assume its like a compressor tank just smaller? 2nd question.

Adding this to my compressor side to air up tires, do I still need a water collector after the booster if the air going in is dry? (guessing yes but wanted to ask)

if it doesnt work I will find something to add it to at some time

ps I  put 40psi going in and had 180 coming out.. not bad for this little booger ... also the fatmax was added so you can see the size of it

Most of these air doubler devices require a secondary tank (which is never big enough) to allow you to actually inflate a coach tire.  They work by halfing your air supply in order to double or tripple etc. it at the output. Net result is very"slow"airing of a tire.

I'd be very curious where you found it for $60.

David,

Yes, the one I got online was $269. without all the pictured things.
Not bad you need very high pressure for a very small volume. Otherwise forget it for coach tires...volume way too great there.

No idea what a Bimba is.

Your booster looks just like mine, only very much smaller. It will deliver the pressure but maybe not the volume you need. No harm in trying.

Mine has no external tank and works great for my tires. Quite fast. I found mine on eBay.

Think the secret is using regular coach air to bring tires to 100 psi or more, then using doubler to top off to your required pressure.

My purpose in having the doubler is top off the tires as needed, not to fill from zero. I've had leaks from the TPMS senders in the past, and needed to bring a front tire from 90psi to 125-120, and a rear tire from 90 to 100. It has worked very well using the booster. More than fast enough for me. Sometimes I don't even start the engine first.

Regarding bimba it's a brand. We have used their pneumatic cylinders for the moving wing on the race car. They make a lot of off road stuff.

I like the price tag for the number of times it would actually get used.

I know I've commented on tire pressures before but, good night!, 125 psi. Why not just pump concrete in and solve the problem?

I am thinking if you need 125 psi in a foretravel  tire, you might be exceeding your axle load rating.

I mis typed. Calculated front tire pressure is 115. I add a few more psi for margin, keeping it under 120.
