Frequently Asked Questions
What size compressor do I need?
Most applications are determined by nozzle size and airflow. Our Compressor Finder helps you choose the correct CFM.
Should I choose a diesel air compressor?
Diesel compressors are ideal where mains electricity isn't available or maximum portability is required.
Do I need an aftercooler?
For abrasive blasting, an aftercooler helps remove moisture from the compressed air, improving blasting performance and reducing wet abrasive.
Which compressor brands do you supply?
CoolBlast supplies portable air compressors from Rotair, Avelair and Applied.
What CFM compressor do I need for sandblasting?
The correct CFM (cubic feet per minute) depends on the size of your blasting nozzle and the type of work you're carrying out. Smaller nozzles may only require around 50–100 CFM, while professional blasting with larger nozzles can require 175–300 CFM or more. Choosing a compressor that is too small will reduce blasting performance and productivity. If you're unsure, our team can recommend the right portable diesel air compressor based on your blasting machine and application.
What compressor is best for dry ice blasting?
The best compressor for dry ice blasting depends on your blasting machine and the amount of airflow it requires. Smaller dry ice blasters may only need around 50–100 CFM, while larger industrial machines can require 125 CFM or more. We supply portable diesel air compressors suitable for leading dry ice blasting systems and can advise on the correct compressor, aftercooler and air treatment package to ensure reliable performance. If you're unsure, use our Compressor Finder or contact our team for expert advice.
