High Vacuum Pump has a two-stage direct drive. The pump produces .1 microns ultimate pressure in laboratory conditions and better than 25 microns in field conditions. It displaces free air at 85 liters per minute (3 cubic feet per minute) at a pumping speed of 1725 RPM. The pump has an oil capacity of 783.7 CC (26.4 oz.) and will perform to specifications in the temperature range of -0°C to 75°C (33°F to 170°F). Intake ports are 1/4 inch OD for 1/4 inch tubing. The pump weighs 12.7 Kg (28 lbs) and includes a removable handle. It is 28.6 cm high by 39.4 cm long by 16.5 cm wide (11-1/4" x 15-1/2" x 6-1/2").

A gas ballast is included to help purge moisture from the vacuum system and a built-in trap reduces the risk of oil-suck-back into the vacuum system.
