The Seamax SUP20D electric air pump is a great option for when you’re blowing up your paddle board in dusty or sand environments thanks to its integrated sand filter.

A versatile and reliable pump, the Seamax SUP20D boasts a fast inflation speed thanks to a one-way diaphragm valve.

This is a durable and reliable pump featuring an integrated sand filter that protects from dust and sand as well as an outtake chamber that reduces the noise of the pump when it is running.

This pump has a carry handle, like iRocker’s, for added portability and a deflation function to help remove the air from your paddle board before packing it away.

The main issue with this pump is that if it overheats the piston seals can melt. The piston seals are an internal part of the pump and it will not function properly without it. Shouldn’t be a problem when only inflating 1 or 2 SUPs.

Additionally, as this pump doesn’t come with a rechargeable battery, you will need a car or battery pack to power it.
