Hi all we still run 5 old Grasso MS compressors, Two high side MS 1030 units and the rest are Low side MS 1034 units built back in 1982 to 1984. They now run 24-7 for 21 days and stoped for 2 days. All that we have done in that time is oil and filters, suction filter, loading gear parts and gland service. On the howdens we have we have had new rotors and bearings, oil and filters and gland service and they are up to 12 years old.
