ABOUT DEFLATION

To do the deflation, you should press open the air valve on SUP and lock it at the open position. First, let the SUP leak out all the high-pressure air until zero pressure. You may only need a few seconds to see the SUP getting flat after the loud air leaking sound. Then you connect the hose to the SUP to do the final deflation.

3 PADDLE BOARDS IN A ROW

Benefit from its temperature control feature, you can feel free to pump up to 3 SUPs without overheating damage issues. otherwise, this pump will auto stop if over the workload and give a beep sound warning.

FOR LEAFIELD C7/D7 AIR VALVES

The package has included the compatible valve fitting for the special Leafield air valve. Seamax also has the original valve fitting kit for sale (Check with our Version 3 air hose kit)

"...your air pump not working properly, such as pressure gauge issue, fuse problem, fan motor issue etc.,..." Read more

"...for it to pump.... Another problem is that it over-heats and shut's down real easily when it's hot out. This is on only ONE SUB!..." Read more

"...One negative is that it can't run off of house current, even if you have a converter. Will run off a vehicle cigarette lighter only." Read more

Quality build, great connectors... just not fast enough, and it overheats

Quality build, great connectors... just not fast enough, and it overheats
I so wanted this to like this pump. Decided to spend the money on the "good one" thinking that I'd have no issues. The build of the unit is great. Super easy to use. The different washers for the SUP connector allow for a perfect fit. I was dismayed to find that it took at least 2x as long for this pump to inflate my SUP as compared to me sweating it out with the cheap, plastic floor pump that came with the boat. But I could almost bear that extra time... until the pump shut off (thermal over-load is my only guess) before my second SUP even reached 4 PSI. The hose right at the connection to the pump was hot to the touch after the first inflation, so when I disconnected (after reaching 15 PSI), I allowed the pump to just blow with no resistance to cool it off. Two minutes later, I began to pump the other boat, but that hose just got hotter (as did the pump, obviously) and it shut down well before getting to pressure. I finished up in a couple of minutes with the manual pump. Ambient temp was under 70 degrees. At sea level for this test. In the shade. Is this normal? Are others able to inflate multiple boards back-to-back?My whole plan for buying this pump was to save time and effort. Pumping even one board at elevation is tough for me. Two boards would just be too much, and it would be so much more enjoyable to effortlessly have them inflated next to the car. Well, turns out that using a cheap floor pump is still better than this. It took 17 minutes to inflate my first boat to 15 PSI (Pic included. Boat is 11 feet x 34 inches x 6 inches thick.). I work up a sweat, but I do it in half that time with the floor pump.Where oh where is that pump that works quickly and without over-heating?
