Description

Edwards EXT 70H 24V compound turbomolecular vacuum pump. Part number B722-26-991, serial 0(contact info removed)6. DN100 ISO-K inlet, KF16 outlet, 24V DC variant. Combines a turbomolecular stage and drag pump on a single shaft — delivers ultra-high vacuum (down to <5x10-9 mbar) with high critical foreline pressure (12 mbar for N2). That means you can run a smaller or dry diaphragm backing pump instead of a large oil-sealed rotary vane. Magnetic and ceramic bearings = oil-free, vibration-free, low-maintenance operation. Specs: - 90,000 rpm, 65 l/s N2 pumping speed - 24V DC (requires Edwards EXDC80 drive module — NOT included) - DN100 ISO-K inlet, KF16 outlet - 2.8 kg, compact form factor - Forced-air or water cooling - Ultimate pressure: <5x10-9 mbar The current-gen replacement (nEXT85) sells for over $8,100 new. This is a zero-hour legacy pump at roughly half that — perfect if you need the exact B722-26-991 part number for an existing system. What's included: Pump only. No controller, cable, or backing pump. You'll need an Edwards EXDC80 24V drive module and a suitable backing pump (E2M0.7 or XDD1 diaphragm) to operate. Ships from: San Pedro, CA Shipping: Professionally packed with inlet blanked, foam-cradled, and insured for full value. Packed weight ~10-15 lb. Signature required on delivery. Local pickup: Available — cash or verified payment at pickup. Important: Do not power on without a functioning backing pump achieving rough vacuum (<1 mbar) first. Operating at atmospheric pressure can severely damage the rotor and bearings. Refer to the Edwards manual before installation (available as PDF on request).
