COMPRESSOR LUBRICATION
CAUTION! Do not operate without lubricant or with inadequate lubricant.
Use of compressor without lubricant or inadequate lubricant voids all warranties.
Synthetic Lubricants
Synthetic lubricants are recommended after 50 hour break-in. Compressor life is greatly increased with the
use of synthetic lubricants. CAUTION! If you will be using synthetic lubricant, all downstream piping material
and system components must be compatible.
Suitable Viton, Teflon, Epoxy (Glass Filled), Oil Resistant Alkyd, Fluorosilicone, Flourocarbon,
Polysulfide, 2-Component Urethane, Nylon, Delrin, Celcon, High Nitrile Rubber (Buna N. NBR more
than 36 Acrylonite), Polyurethane, Polyethylene, Epichlorohydrin, Polyacrylate, Melamine,
Polypropylene, Baked Phenolics, Epoxy, Modified Alkyds
( indicates trademark of DuPont Corporation)
Not Recommended
Neoprene, Natural Rubber, SBR Rubber, Acrylic Paint, Lacquer, Varnish, Polystyrene, PVC, ABS,
Polycarbonite, Cellulose Acetate, Latex, EPR, Acrylics, Phenoxy, Polysulfones, Styrene Acrylonitile
(San), Butyl
Alternate Lubricants.
You may use petroleum-based lubricant that is premium quality, does not contain detergents, contains only
anti-rust, anti-oxidation, and anti-foam agents as additives, has a flashpoint of 440°F (227°C) or higher, and
has a auto-ignition point of 650°F (343°C) or higher.
See the petroleum lubricant viscosity table below. The table is intended as a general guide only. Heavy duty
operating conditions require heavier viscosities. Refer specific operating conditions to NorthStar Customer
Service at 1-800-270-0810 Monday - Friday 7:00 AM-5:30 PM, Saturday 7:30 AM-11:30 AM Central Standard
