Frequently asked questions
What exactly is included at each tier?+
Base is the extractor without ancillary equipment. Starter is Base plus a recovery tank, JIC lines and a vacuum pump. Turnkey is Base plus Starter plus a vacuum oven and a scale.
What is the pressure rating and vessel material?+
304 stainless steel throughout, rated 150 psi, with Buna-N gaskets. A 150 psi pressure relief valve on a 1/4" MNPT port and two glycerin-filled -30 to 150 psi gauges are included.
Which solvent is the system designed for?+
Pure butane. The system is passive, so pressure is changed by temperature rather than by a recovery pump. Operate in a well-ventilated area and in accordance with local codes.
What are the lid connections?+
2x 1.5" tri-clamp, 1x 2" tri-clamp, 2x 1/4" FNPT and 2x 1/2" FNPT on the 8" hemispherical lid.
What is in the base packing list?+
8" hemi lid; 8" x 8" tri-clamp spool; weld-base 8" x 2" splatter platter; 1.5"-to-4" hemi reducer; two 2" sight glasses; 2" tri-clamp SS304 1000 psi ball valve; 4" tri-clamp filter plate kit with 100 micron mesh and filter ring; 4" x 24" tri-clamp spool; 4" showerhead cap with 1/4" FNPT; Superlok 1/4" and 1/2" valves with NPT and JIC adapters; two glycerin-filled gauges; a 150 psi relief valve; and the tri-clamps and Buna gaskets in 1.5", 2", 4" and 8" sizes.
How does this compare with the 1 lb column?+
The 2 lb unit takes 900 g of material against 450 g, and steps the collection path up from 3" to 4" (4" filter plate, 4" x 24" spool, 4" showerhead cap) with an 8" rather than 6" lid. Both are rated 150 psi in 304 stainless with Buna-N gaskets.
