The GENTOS black air duster HTF-5L is perfect for cleaning precision instruments. - Brand: GENTOS - Model Name: HTF-5L - Color: Black - Type: Air Duster Thank you for viewing. I purchased this at Kohnan Pro for around 10,000 yen and only tried it two or three times. I intended to use it for work, but it wasn't what I was looking for, so I'm selling it. It has a strong airflow. I think it's also good for blowing away dust and sand, such as for campfires. It can also be used to blow away water droplets when washing a car.
