Use a good grade of
industrial type
non-detergent, rust
inhibiting, anti-foaming oil and of correct viscosity per Table
2. Roots Synthetic Oil (Roots P/N 813-106-) is
specified
and recommended
. Roots does not recommend automo-
tive type lubricants, as they are not formulated with the
properties mentioned above.
Due to sludge build-up and seal leakage problems,
Roots recommendation is DO NOT USE Mobil SHC
synthetic lubricants in Roots blowers.
*Ambient temperature is defined as the temperature of the space in which the
blower and drive are located.
These capacities are provided to assist stocking the correct amount of oil. Exact sump capacity may differ slightly.
See “Lubrication” section for proper filling instructions.
