Kit Contains: 2 Replacement Cylinder Sleeves (Replacement For One Compressor)
Keep your compressor running at its highest efficiency by replacing your filters at least once a year. A compressor running 24/7 can cause air filters to get dirty quickly. We recommend changing the Solaer™ Air Filter Felt once a year or as needed.
Fits: SB-1.1, SB-1.2, SB-1.3 & SB-1.4
