These are compact, high performance units featuring either the 63 mm or 100 mm Diffstak both backed by the RV5 two-stage rotary pump. Inlet pumping speeds above the valve are 135 l s-1 and 280 l s-1 respectively.
The Diffstak has an integral water cooled baffle and is fitted with manual quarterswing and backing/roughing valves. A manual air admittance valve and a Pirani gauge are fitted in the backing line to the rotary pump. The unit is supplied complete with rotary pump oil but vapor pump fluid should be selected from the fluids and sealants section. Additional gauges are optional extras (see page 11-7). 1
*A separate display or controller is required to show the pressure measured by the Pirani gauge head. |
