MiniStar 1213/1220


Our MiniStar Linup has the smallest footprint of all our insulation blowing machines, but that doesn’t mean they can’t pull their own weight. These machines are built for retrofits. If you want to be able to hop from home to home adding bulk insulation to attics, and dense packing insulation in wall cavities, then our MiniStars are right for you.

The MiniStar 1213 is our base model, equipped with a 13.5 HP Honda Engine. Our MiniStar 1220 has all the power of the base model, but upgrades the 13.5 HP engine to a 20 HP Honda® Engine. This extra power helps drive the optional four-finger shredder system, macerating the insulation more effectively so you can get more spread from each bag.

Optional Upgrades

Four-Finger Shredder System

The Four-Finger Shredder System is the ideal upgrade for fiberglass or rockwool insulation blowing applications. The extra row of shredders help to better aerate the material and maximize the yield from each bag of insulation used saving you up to 10% every time!

Wireless Remote Upgrade

Control your Star Machine Insulation Blower from up to 500′ away with the Wireless Remote Control Upgrade.


Star Machine knife and paddle augers are designed to be aggressive on tightly packed insulation. Our augers break up the product before it enters the shredder system.


All Star Machine Insulation Machines have double finger shredders installed as standard. These shredders work together to separate the insulation material to get you the most coverage.

Housed behind hinged doors at the front of the airlock for easy access while cleaning or during maintenance.

*Optional four-finger shredder available
