Industrial applications
Premium Zinc-Free Industrial Hydraulic Fluid
Shell Te llus S3 M hydraulic fluids are high performance lubricants tha t use exclusive zinc-free technology to provide outstanding protection and performance in most manufacturing and ma ny mobile equipment operations. They resist breakdown under heat or mechanical stress, helping to prevent da ma ging deposits tha t can decrease the efficiency of your hydraulic system.
Performance, Fea tures & Benefits
Main Applications

Long fluid life – maintenance sa ving
Shell Te llus S3 M fluids offer an improved ca pa bility to extend
fluid maintenance intervals and hence reduce equipment
downtime through:

Manufacturing and industrial hydraulic systems Shell Te llus S3 M fluids are suitable for a wide range of
hydraulic power applications found in manufacturing and industrial environments.

An extended ASTM D943 TO ST lifetime, with an oxidative stability tha t is designed for a minimum 5000 hours TO ST life.

Excellent resistance to breakdown in the presence of wa ter
and heat.

Severe duty hydraulic service The long-life characteristics of Shell Te llus S3 M fluids can ma ke
them pa rticula rly suitable for severe duty (e.g. loa d,
temperature) applications
These features provide extended maintenance ca pa bility
without compromising protection or performance, even under
severe or extended temperature range applications.

Outstanding wear protection
or where extended life is required (e.g. Re mote or inaccessible
locations).
Advanced zinc-free anti-wear additives provide protection over a wide range of conditions, including low and severe
duty, and high loa d operation. This protection has been demonstrated in tough industry standard hydraulic pump tests such as the Denison T6H and Ea ton Vickers 35VQ25 tests.

Marine and mobile hydraulic systems
Shell Tellus S3 M fluids are suitable for marine and mobile applications where ISO HM type hydraulic fluids are
recommended.
Low toxicity towards the environment
Maintaining system efficiency
Shell Tellus S3 M has a reduced environmental impact in the event of a leak or accidental spilla ge compared to conventional zinc-based hydraulic fluids. This is achieved through the use of zinc-free anti-wear technology and low sulphur base oils. Shell Tellus S3 M is classified as ‘not harmful’ to freshwater and marine invertebrates when tested as water-accommodated fractions (WAFs) according to O ECD and EPA test guidelines.
Superior cleanliness and filterability; coupled with excellent water separation, air release and a nti-foa m characteristics, all help to ma inta in or enhance hydraulic system efficiency. The filterability of Shell Te llus S3 M is maintained even when the fluid is contaminated with water.
Shell Te llus S3 M fluids ha ve a ISO 4406 cleanliness of 2
1/ 19/ 16 or better ex Shell filling lines. As recognized by
For further reductions in environmental impact, we offer the Shell Naturelle range of environmentally considerate lubricants.
DIN 51524 specification, the oil is exposed to various
influences with transport and storage tha t could effect the
cleanliness level
For applications that experience wide temperature variations we recommend the Shell Te llus “V” series of hydraulic fluids.
