Max Air 35 Electric


from Hartford, CT, US

I decided to order the Max Air 35 Electric single phase for a home fill station in my basement. I ran fresh air intake from outside to the air filter, as well as outside vent to dump the condensate relief. I am extremely satisfied with my purchase thus far. I have had it for a few weeks now, and have filled about 15 tanks with it. It is smaller than I thought it would be, and runs relatively quiet. I enjoy the digital hour meter as it allows me to keep diligent track of filter and oil change life. I ordered the manual drain, as I usually am hanging around the compressor when its running. I contacted Max Air directly, and Kelly at Max Air was extremely helpful with all the questions I had regarding the compressor. He is very knowledgable and communicates effectively and in a timely manner. I wish I had purchased this years ago!! Averaging out the price of the oil and filters, I can fill a HP steel 100 in the comfort of my own home for about $1.50. Thats cheaper than any other dive shop! Dive Dive Dive!!!


Air off the beaten track


Given our remote location in Northern Haiti, this little compressor is great to keep our tanks full without having to drive 6 hours to the nearest dive shop. We recommend the Max Air for experienced divers going to far away places.

Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  Why Did You Choose This?
BRANDON B  I use it on a sailboat, it is small and packs away when not in use. It does the job
Shopper  Is there an increased risk of carbon monoxide contamination in the tanks with the gas engine model? Would it be important to purchase the "Max-Air Air Line Visual Moisture/CO Indicator"?
Andrew M  Like any engine if you are filling the tanks in an enclosed area there's a risk of carbon monoxide in your tanks. It is strongly suggested that you place the air suction hose upwind and an outside area when charging your tanks. as it relates to the moisture indicator, I strongly recommend you get that.
Dave L  how much gasoline would the compressor use to fill an 80 tank? my boat runs on diesel so carrying gasoline is not that convenient'
KEVIN F  According to the manufacturer: "The 35 GS and GH hold just over 1 gallon of fuel, both varying a little, but run for nearly 2.5 hours on one tank. So, each tank will get close to 6 fills, so essentially you have 1.06 / 6 tanks (80’s) for .17 gallon of fuel per fill. That’s as close as I can figure, given the variables of heat, humidity, max rpms and such."
