The new Rotair D300T4F is a compact, quiet, and powerful air compressor that delivers enough air to run a #7 sandblast nozzle, and save fuel at the same time. This is a good in-between compressor size, and substantially less expensive than all 375 cfm offerings. This compressor has also been a great match for many Vapor Blast machines on the market. It's compact size and available skid base makes it perfect for mounting on a trailer with a 650 lb Vapor Blast machine. The D300T4F meets Tier 4 Final emissions standards without a costly and high maintenance Diesel Particulate Filter, and does not require a Diesel Exhaust Fluid system. This machine has proven itself to be a great 375 class compressor alternative for about 40% less than the competition.
