Welch 1399B-01 Single Stage Duoseak Vacuum Pump – 1.2 CFM The Welch 1399B-01 Single stage vacuum pump is a rugged and robust vacuum pump for applications requiring pressures < 30 Torr. The Welch 1399B-01 achieves < 0.030 Torr with a pumping speed of 35 liters/min (1.2 CFM). Single stage, oil sealed vacuum pumps should not be operated continuously at pressures above 30 Torr. Operating this vacuum pump at higher pressure will induce excessive oil spraying from the exhaust of the vacuum pump causing premature failure and void warranty. Please consult your Chemtech Scientific Representative for consultation, should the ultimate pressure of your process run above 30 Torr. This is the fully mounted version, complete with base and motor, making it ready for immediate installation and use. Key Features 1.2 CFM (35 L/min) pumping speed Ultimate vacuum down to < 0.030 Torr Single-stage rotary vane design Large oil reservoir for cooler operation and longer oil life Durable DUOSEAL construction Easy maintenance access Ideal Applications Laboratory vacuum systems requiring moderate vacuum Vacuum filtration Vacuum ovens and drying (moderate vacuum needs) Degassing Light industrial processes The Welch 1399B-01 is a reliable single-stage pump from the trusted DUOSEAL series, ideal for applications where deep vacuum is not required.
