Compressed air used for Scuba should smell like regular air. There may be a slight rubber smell from the regulator. When in doubt, it is safer to get your tank refilled than to dive on contaminated air.
An air conditioner should not smell like smoke when turned on (or when turned off). I would have to suspect that the electrical insulation is burning.
I'm almost positive they make air fresheners that smell like roses. And if they don't, then they should. If you want to buy some air fresheners (I'm not saying they smell like roses)
no because gas is a diffrent form of air that can kill air fliter cant
seriously? it is not diving and you don't scuba to breath in air.
Most SCUBA divers dive with compressed air, which is normal atmospheric air compressed into a scuba tank.
You need a buddy in scuba in case something happens, like you run out of air or something. You definitely always need a buddy in scuba!!!
I would think so, because there are two of them mixed together. Air in a scuba tank or anywhere else should be heterogeneous. A scuba tank filled with either oxygen or nitrogen would be homogeneous.
By having a bubble of air connected to the lungs - like scuba gear.
Tanks are used to hold air like you breath above water. They do go thru a filtering process that removes the water and other things in air that can harm a diver. Scuba air from a reputable source is very clean and dry.
A scuba diver can purchase many things for scuba diving at the Air Hog online shop. They can purchase dive knives, dive lights, dive computers, and dive bags which will help them in scuba diving.
like normal air
Scuba divers require increased air pressures in their air tanks while diving because the pressure on their bodies increases.
