Excellent for challenging fabrics such as fine knits and stretchy materials, the Brother AIRFLOW 3000 Jet Air overlocker can achieve outstanding finishing touches with flatlock, overlock, and rolled hem stitches on most specialty fabrics. The modernistic AIRFLOW 3000 can cut and finish seams all in one pass. It’s a breath of fresh air to change threads as the AIRFLOW 3000 threading ports are connected to the end of each looper by tubes, and at the touch of a button, a blast of jet air sends the threads through the loopers, so it’s a cinch to change thread colors.
