Make sure all of your hoses and nozzle sizes are correct.
Filters tend to be installed between the compressor and blast pot. People tend to think filters have moisture eliminators in them. They do not. Filters strain air. Filters are designed with a lot of pressure loss in them or they never get serviced, therefore the element in the filter gets dirty and it no longer allows the right amount of volume to come across. Filters just by nature are restrictive. Make sure they are serviced regularly.
If anybody is installing any type of regulation on the airline, make sure the regulators are designed for the correct volume of air. Make sure it is a quick responding regulator. Slow reacting regulators have a negative effect on blasting equipment. Make sure you are using the proper size and style of regulator for your element.
