All of the blower lubricants carried by pdblowers should be stored in a clean dry location, kept above freezing. While our main three lubricants are very similar and can be assumed to have similar lifespan, each manufacturer has provided varying guidance:
- pdblowers synthetic oil – shelf life is at least 3 years from date of manufacture
- Roots synthetic oil – “Product shelf life is 3 years from the date of manufacture, after which the product should be recertified prior to use.”
- Aeon PD synthetic oil – minimum of 5 year shelf life if properly stored
For the greases used on blowers, the ASME standard shelf life is 1 year. After this time the thickening agents will start to separate.
