Hello Graywolf, we are the Fushbros and share a common friend with Chuck @emeraldtrianglegenetics. We've developed a new recovery pump (the FB710). It's an electric dual diaphragm pump (110 or 220v). Made in the USA. Oil free, super-quiet, requires minimum maintenance, 103PSI, Class 1 Div 1 group C & D, preliminary approval from PSI in Colorado. Asking if you can demo it; we'd appreciate your help. Thanks.
