Shell Torcula Oils have been developed to meet the special lubrication requirements
of all percussion type pneumatic tools, including those subjected to the most
arduous conditions. They are based on a blend of highly refined mineral oils and
selected additives chosen for their ability to maintain high oil film strength and
effectively lubricate the demanding requirements of pneumatic drill impact
mechanisms.
Applications
* Percussion type pneumatic tools, including * Good low temperature fluidity
those used for rock drilling Remains mobile at low temperatures and resist
oil build-up in areas cooled by rapid air
* Oil mist lubrication systems and air tools expansion.
* Air tools * Excellent corrosion protection
* Gear and bearing lubrication systems subject Provide high levels of corrosion protection even
under severe water wash conditions.
