Available as a standalone device, the Grain Portr works with any style cofferdam. Allows the rescuer to quickly remove grain from inside the cofferdam, thereby freeing the subject. Requires no electrical power. Very compact and lightweight making it ideal for use in a confined space such as a grain bin. No participation from the patient is required as it is when using buckets. Removes grain faster than a typical vacuum and creates very little dust, especially inside the cofferdam.
