Moisture is the number one enemy of any blasting contractor.
Did you know that blasting with dry air can increase your blasting efficiency by as much as 15%?
We should not under estimate the benefits of using cool, dry air for blasting. It is true that many blasters who use AirPrep moisture removal systems find that cool, dry, compressed air actually allows them to blast up to 15% faster! Yes — that means more than one hour extra blasting each eight hour day, free!!
The air all around us contains water vapour - This changes by the day. When there is a lot of water vapour in the air it can cause problems for the blaster.
Your air compressor draws in this air (and water vapour) 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.
Moist air is heavier and can waste a lot 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 does blast 15% faster than moist air. So you too can blast faster and increase your profits by simply drying your compressed air!
But there are other advantages as well.
Compressed air is costly. Fuel, repairs, regular maintenance on compressors is a large expense for Specialist Blasters.
With the correctly sized compressed air dryer you can achieve less than two psi pressure loss across the whole system and that means you can blast with high productivity without a high pressure drop across the radiator.
