The NCDF Series vacuum pump efficiently generates a high vacuum flow and a high exhaust flow using a small amount of compressed air, with amplification ratios up to 40:1 (output to input). NCDF's are ideal for applications that require high levels of flow such as the rapid evacuation of fumes, blow drying wet materials, or to cool hot areas and/or materials. NCDFs generate high vacuum flow, overcoming leaks inherent in handling porous objects such as cardboard, foam or fabric.
