MODEL CR-100 SERIES TWO STAGE AIR COMPRESSOR PARTS AND SERVICE

Oil

FS Curtis MasterLine compressors require a 500h break in period and units are factory filled with the needed lubricant for the break in period (FSC-1000 for ML, FSC-1000A for all Large Industrials). After the break in period is complete, drain the oil and replace with required oil for your compressor listed below. NOTE: Basic Pumps are not filled from the factory!

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 is a non-Detergent type oil 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.

MONTHLY MAINTENANCE

•             • Check motor belt tension.

•             • Check fan belt tension (C200, C260, and C300).

•             • Check bolt torques, pulley clamp screws, and jam nuts for tightness. Torque if necessary

•             • Inspect entire air distribution system for leaks.

•             • Check all connections (mechanical and electrical) and tighten as necessary.

EVERY THREE MONTHS

•             • Change oil (more frequently in harsher environments).

•             • Inspect valves for rust, wear, and carbon build up

•             • Check air filter for cleanliness and replace if necessary

•             • Replace Oil filter and clean oil strainer (Large industrials)

EVERY SIX MONTHS

•             • Replace air filter

DAILY MAINTENANCE

•             • Check oil level. Check oil for discoloration and filth. Drain oil and replace if required.

•             • Drain drip legs and traps in air distribution system.

•             • Open drain cock located at the bottom of the tank to relieve condensation.

•             • Drain intercooler (Large Industrial)

•             • Check for oil leaks.

WEEKLY MAINTENANCE

•             • Manually operate the pressure relief valves to be certain they are working.

•             • Clean the cooling surfaces of the intercooler and compressor.

•             • Check the compressor for air leaks.

•             • Check the compressed air distribution system for leaks.

•             • Check Oil Pressure, record reading at oil change (Large Industrials) 

Maintenance

For the first weeks, the compressor needs time to “break in.” The belt requires time to stretch and fit into the surface of the pulleys. The piston rings need time to seat themselves into the cylinder walls, and bearings need to wear into place. For the first 100 hours or so, the compressor will consume higher than normal amounts of oil until the break in process is complete.

FIRST MONTH MAINTENANCE

•             • Check oil level at the beginning of every week, fill as needed, see oil subsection.

•             • Check belt tension at the beginning of each week and tighten as required, see belt tension subsection.

•             • Check bolts, pulley clamp screws, and jam nuts for tightness. Torque if necessary (see bolt torques subsection) 

Maintenance Schedule

To assure maximum performance and service life of your compressor, a routine maintenance schedule should be developed. A sample schedule has been included to help you develop a maintenance schedule designed for your particular application. Time frames may need to be shortened in harsher environments or during periods of extremely heavy use.

MODEL C-100 TWO STAGE AIR COMPRESSOR PARTS AND SERVICE

Base mounted Large Industrial compressors are capable of outing large amounts of air at high pressures and come in single stage, two stage, or high pressure varieties. They work off the same basic compressor cycle that tank mounted units operate on. NOTE: As these units do not come with a receiver tank, the installation of safety valves in the discharge line is the responsibility of the end user.

Maintenance

For the first weeks, the compressor needs time to “break in.” The belt requires time to stretch and fit into the surface of the pulleys. The piston rings need time to seat themselves into the cylinder walls, and bearings need to wear into place. For the first 100 hours or so, the compressor will consume higher than normal amounts of oil until the break in process is complete.

FIRST MONTH MAINTENANCE

•             • Check oil level at the beginning of every week, fill as needed, see oil subsection.

•             • Check belt tension at the beginning of each week and tighten as required, see belt tension subsection.

•             • Check bolts, pulley clamp screws, and jam nuts for tightness. Torque if necessary (see bolt torques subsection) 

Maintenance Schedule

To assure maximum performance and service life of your compressor, a routine maintenance schedule should be developed. A sample schedule has been included to help you develop a maintenance schedule designed for your particular application. Time frames may need to be shortened in harsher environments or during periods of extremely heavy use. 

DAILY MAINTENANCE

•             • Check oil level. Check oil for discoloration and filth. Drain oil and replace if required.

•             • Drain drip legs and traps in air distribution system.

•             • Open drain cock located at the bottom of the tank to relieve condensation.

•             • Drain intercooler (Large Industrial)

•             • Check for oil leaks.

WEEKLY MAINTENANCE

•             • Manually operate the pressure relief valves to be certain they are working.

•             • Clean the cooling surfaces of the intercooler and compressor.

•             • Check the compressor for air leaks.

•             • Check the compressed air distribution system for leaks.

•             • Check Oil Pressure, record reading at oil change (Large Industrials) 

MONTHLY MAINTENANCE

•             • Check motor belt tension.

•             • Check fan belt tension (C200, C260, and C300).

•             • Check bolt torques, pulley clamp screws, and jam nuts for tightness. Torque if necessary

•             • Inspect entire air distribution system for leaks.

•             • Check all connections (mechanical and electrical) and tighten as necessary.

EVERY THREE MONTHS

•             • Change oil (more frequently in harsher environments).

•             • Inspect valves for rust, wear, and carbon build up

•             • Check air filter for cleanliness and replace if necessary

•             • Replace Oil filter and clean oil strainer (Large industrials)

EVERY SIX MONTHS

•             • Replace air filter

Oil

FS Curtis MasterLine compressors require a 500h break in period and units are factory filled with the needed lubricant for the break in period (FSC-1000 for ML, FSC-1000A for all Large Industrials). After the break in period is complete, drain the oil and replace with required oil for your compressor listed below. NOTE: Basic Pumps are not filled from the factory!

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 is a non-Detergent type oil 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
