Posted in Abrasive & Water Blasting Tip: #12 Never underestimate the benefits of using cool, dry air for blasting Many blasters who use air preparation moisture removal systems find that cool, dry, compressed air actually blasts up to 15% faster. Your air compressor draws in this air (and water vapor) and compresses it to 100psi. The compressor takes in 8 cu ft of free air to make 1 cu ft of compressed air. This, of course, means that you've got 8 times more moisture in that newly compressed air. How Can You Increase Your Profits by Using Dry Air? Moist air is heavier and can waste 15% of your available energy in carrying this moisture through your system. An efficient blasting operation needs all the energy it can get to propel the abrasive to the surface being blasted! That's why specialist operators claim that clean, dry air blasts 15% faster than moist air. So you too can blast faster and increase your profits! Where's the pressure? Other Advantages of Dry Air Compressors generate heat through the compression process and because the air is hot more moisture can stay suspended as vapor in it. This air cools down as it travels through your blast machine and into your blast hoses. As it cools and the vapor condenses into water it can cause you problems. We all know that water in abrasive will cause the abrasive to clog and prevent it from flowing easily. Wet abrasive requires you to 'choke' the pot to unblock the lines. Dry air keeps your abrasive flowing and easy to control. By removing moisture you almost never need to choke your blast machine to unblock the system again. By adding an AirPrep system to a blasting package to dry the air and by setting up the abrasive metering valve to perfection, many blasters find they use 25% less abrasive. This in turn means that you are only cleaning up and disposing of 25% LESS abrasive waste. Increase Your Profits with a Moisture Removal System Once you remove the moisture you won't get that black moisture shadow's that follows your blast nozzle as you blast and causes the surface to flash rust. If you run pneumatic equipment such as Graco spray pumps on clean dry air the machines are much less likely to have icing up problems. They require a lot less maintenance and last longer. You will also prevent quality issue which result from water droplets on your freshly blasted steel surface or newly painted surface. Compressed air is costly. Fuel, repairs, regular maintenance on compressors is a large expense for Specialist Blasters. An AirPrep™ system makes the most of your air investment by making the air work more efficiently.
