These Agilent Varian model AX-65 high vacuum diffusion pumps are air cooled and the primary industrial standard for compact high vacuum pumping. The Agilent Varian AX-65 diffusion pumps have a high pumping speed for all gases and the lowest cost per unit pumping speed when compared with other types of pumps used in the same vacuum range. The AX-65 pumps feature glass fill and drain assemblies for easy maintenance of diffusion pump fluid and continuous monitoring. These AX-65 models include a finned boiler which increases the surface area and prolongs fluid life. The full fractionating design allows vaporized fluid to be fractionated in the boiler and jet assembly. Contamination and decomposition products are pumped away and only the purest vapor reaches the top jet, assuring highest speed and lowest backstreaming.

This is the fan universal voltage 115-230 VAC for the AX-65 Diffusion Pump. This is the fan only pump not included. For location of fan see item #8 on (diagram exploded view & parts illustration) below.

This is a (Optional) Pump Ready thermal switch. This thermal Pump Ready switch, is to be attached to the side plate of the AX-65 Pump next to the over temperature thermal switch. This optional thermal switch can be connected to a light to show when the pump is at operating temperature. It is normally open and closes when the pump reaches operating temperature. The switch is set to close at 170ºF (operating temperature). See graphic for installation/location on the pump.

This is a 365ºF replacement thermal switch for the following AX-65 diffusion pump heater harnesses: 200W, 115 VAC heater harness, PN L9994307 250W, 115 VAC heater harness, PN L9994303 200W, 220 VAC heater harness, PN L9994308 250W, 220 VAC heater harness, PN L9994304 250W, 165 VAC heater harness, PN L9994302 250W, 90 VAC heater harness, PN L9994301 This is a replacement over temperature thermal switch. A normally-closed, over temperature thermal switch has been attached to the diffusion pump body via the heater harness on the side of the pump. Loss of cooling, high temperatures, high pressure, or low fluid level causes the contacts of the thermal switch to open. When the problem has been corrected, the thermal switch automatically resets to closed. The switch is set to open at 365ºF. See #6 on (diagram exploded view & parts) illustration below for location.
