Oil
FS Curtis MasterLine compressors require a break in period and are factory filled with the needed
lubricant for the break in period. After the break in period is complete, drain the oil and replace with
required oil for your compressor listed below.
FS Curtis manufactures two different lubrication systems for Masterline compressors.
The compressors D96, D97, C79, C89, C98, and C100 use an oiling ring system. Use ISO68 FSC-
1000 Premium Reciprocating Compressor Lubricant. This oil is specially formulated for Curtis
Reciprocating Air Compressors and includes non-Detergent type with anti-foam, anti-rust and oxidation
inhibitors.
Use ISO100 FSC-1000A for break in and regular use if ambient air temperatures exceed 90°F.
Large industrial units C200, C260, and C300 have an oil pump system and operate under very high air
pressures and temperatures. Use ISO100 FSC-1000A. This oil is blended for FS Curtis large
industrial units.
For Large Industrials C150H, C260H, and C300H, use ISO100
FSC-1000S synthetic oil. For all other large industrials, use
ISO100 FSC-1000A. For proper lubrication the compressor shall not
be operated below the minimum or above the maximum R.P.M.
recommended for the various models.
1. Maintain oil level mid-way between the upper and lower lines of the
crankcase sight gage. Fig. (14) Oil sight glass reading
2. Stop compressor to add and gauge oil.
3. Do not fill above the upper line and do not operate compressor with oil level below the lower line.
NOTE: ISO100 FSC-1000S synthetic oil is available as an option on all Masterline Compressors.
Using synthetic oil will significantly extend the life of your compressor.
