Production
of DC 704 has been discontinued. It served vacuum industry well for about 20
years. But in last 20 years technology has taken a big leap. To increase
productivity Vacuum pumps need to work faster, higher level of vacuum is
required by industry. Above all because of increasing competition Industry
wants cost effective products. All these factors led to development of better
Diffusion Pump Oils, ultimately wiping out DC 704.
An
Indian company Supervac Industries has developed such a Diffusion Pump Oil.
This oil is called High Vacuum Silicone Diffusion Pump Oil : SV-SIGMA.
This is next
generation oil much ahead of now discontinued DC 704 in technology. Indian
Vacuum Industry which is one of largest in world has been using this oil since
last about 8 years. Supervac Industries also exports SV-SIGMA oil to 16 other
countries.
SV-SIGMA has a very long life, fast vacuum time and
gives vacuum of the order of 1 x 10-8 Torr. Price is very
competitive. If you are looking for an alternative to DC 704, look no further,
