I have one and it works fine with the fine blasting media from TSC -red bag. I use 90 lbs of pressure from my 80 gallon 2 stage 140lb pressure air compressor with water seperator. You need to cover up, the TSC media has no silica but I still wear a non hardner respirrator , goggles, cap, shirt and end up with sand in my ears and clothing. I use it outside. Pressurize pot tank, turn on media valve on bottom to half - blast away. When done, leave blast on, turn off bottom media valve ----- turn off pot air fill valve ---let pot tank pressure blead off --then close blast valve on the end of hose. All valves on tank are closed at end.

Keep media dry in pot tank. My HF blaster has all ball valves -- no deadman valve. Saves time and money on many items to blast. I live out in the coutryside and the blasting media ends up in my gravel drive.
