Filter Element for Oil-Free Air

The SPEEDAIRE 4GPD8 is an activated-carbon filter element rated at 0.01 micron with a Microglass medium. It is designed for compressed-air systems that require oil removal to meet ISO 8573 purity classes. Compatible Grainger part numbers include 35GN18, 35GN22, 4GNN4 and 4GNW6. The unit ships new and carries California Proposition 65 warnings for cancer and reproductive harm.

Sustained Flow and Contaminant Capture

At a maximum flow rate of 15 cfm the element continuously adsorbs oil vapour and fine particulates without the pressure spikes seen during short purge cycles. The Microglass structure maintains consistent resistance over extended runs, preventing the gradual efficiency drop that occurs when media loads unevenly. This steady performance keeps downstream equipment protected during long production shifts.

ISO 8573 Compliance Limits

The filter is built to the ISO 8573 standard, which defines maximum allowable oil and particle concentrations for compressed air. Meeting the standard depends on staying within the rated 15 cfm flow and replacing the element before saturation exceeds the 0.01 micron rating. Systems that exceed this flow or defer maintenance will fall outside the certified purity classes.
