if so any mod necessary to make sure not to bust the LE?

Dial the pressure down and install a particle filter in the line. It'll keep the scraps of metal and rust laying around in the resevoir from shooting holes in your bladder.

Kinda heavy though to be portable and requires an electricity source.but if you're house/cottage is on the beach, they work sweet. Just gotta be careful not to overinflate it.

I doubt it has enough volume to air up a kite. I have an onboard compressor on my truck I built for kite boarding. I have a 20gal tank that I fill up to 140psi. It has enough air on a full charge to air up 3 kites. The local shop has a 60gal tank that they fill up to 100 psi and they only get 6-7 kites filled if they are smaller kites and not lightwind kites.

It takes a lot of compressed air volume wise to fill a kite. It will work for you but you might have to recharge half way thru your pump up as most compressors are high pressure low flow. Where as our hand pumps are high flow low pressure.

You'll need to be very careful not to blow the little ball into the kite. Dialing down the pressure can help. In addition, you'll need about more capacity to fill just one kite.
I have a similar setup but added an additional 7gal. Tank. I've added a second battery to my truck so it doesn't cy cle quite as frequently.

Some context, by example:

Current high-capaciity hand pumps move about 2 litres of air with each stroke, up or down. So an up-down double stroke pumps about 4 litres (1 US gallon).

If it takes 50 double strokes to fill a kite to atmospheric pressure (about 15 pounds per square inch), that's about 200 litres (50 US gallons). It'll take about half that many double strokes again to further pressurize the kite to about one half over atmospheric pressure (another 7-8 psi). So, that particular kite needs about 300 litres (75 US gallons) in total.

If you use a tank of air compressed to 150 psi, for example, that's 10 times atmospheric pressure, and since pressure and volume are inversely proportional, you'd need tank capacity of 1/10th that of the kite's requirement. That means a 7.5 US gallon tank, pressurized to 150 psi, would just barely do the job for that particular kite.

Cheers, and happy new year,
James

More like set at 60-80psi. It takes forever to pump up at 10psi.

These pumps are what we've needed for a long time.....portable, high pressure, with a sand filter, and allows you to connect to your kite, walk out your lines, and come back to a fully inflated kite.

Millera, looks fantastic.

Bravo BST is also the same product, but not so hapy with its quality...need to try this oe.

Sandfilters sounds perfect!

I cannot see the max pressure it can pump...do you know up to how many psi it can pump?

Hi Toby,
The max pressure is 12psi. It has a digital screen and you can increase the pressure in 0.15psi increments. I think this is better than the bravo pumps. You can connect the pump to you kite and walk away.
