AC 725는 Silicon 계 고 진공 확산펌프 오일로서 DC 705
같은 structure formula(분자구조)로 제조되어 DC 705등의 Silicon계 Diffusion
pump oil와 동일한 특성과 성능을 가집니다. 열에 대한 내 산화성이 좋아서 공정 중 산소에
노출되어도 성능저하가 거의 없어 타 오일에 비하여 더욱 오래 사용할 수 있습니다.

BENEFITS
AC 725 Diffusion Pump Oil offer the following benefits;
Shorter conditioning runs : Single-component silicone
oil reach maximum potential in far less time than that
required for multi-component organic oil.
Faster pumping : Diffusion pumps using silicone oil
can operate against 20 to 300 percent higher fore-pressures
than those using organic oil.
Minimal back-streaming : The vapor pressure of single-component
silicone oil from so low the use of traps or refrigeration
of existing traps
Faster cycling, reduced downtime, less frequent oil
replacement :
The recovery rate of silicone oil after exposure to
air at operating temperatures is many times faster than
that of organic oil.
