The Super Silent 50-TC is a 1/2 HP oil-lubricated air compressor designed for quiet, reliable operation in professional jewelry and engraving environments. Running at just 40 dB, it delivers 2.0 CFM (56 liters per minute) of compressed air at a maximum 114 PSI (7.9 bar) into a 0.9-gallon tank. Automatic operation and built-in thermal overload protection make it a low-maintenance workhorse for single-apparatus use. Recommended for powering pencil bead blasters and GRS engraving systems including the Graversmith, Gravermax, Gravermate, Gravermax SC, Gravermax G-8, Gravermach, Gravermach AT, and GRS System 3. For users who frequently run multiple tools simultaneously, the larger-tank Sil-Air 50-15 or Val-Air 50-15AL may be more suitable, as their greater storage capacity reduces how often the motor must cycle.

Notes
Maintenance: Super Silent air compressors use a specially formulated hygroscopic compressor oil that draws moisture from the air during compression. Change the oil regularly based on usage and workshop humidity — if the oil appears milky white, it has absorbed excess moisture and must be changed immediately. Check and empty the moisture trap at the output regulator whenever it is full. After each use, release compressed air from the tank to prevent condensation buildup, which can cause internal rust over time. These routine steps protect the compressor's internal components and extend the life of the tank.
