SPEEDAIRE 4GPG2 Pre-Filter Element

This SPEEDAIRE 4GPG2 pre-filter element removes particulate from compressed air systems. It uses a microglass filter media rated at 5 micron to capture fine contaminants before they reach downstream equipment. The unit handles a maximum flow rate of 147 cfm and conforms to ISO 8573 standards. It is compatible with Grainger part numbers 35GN50, 4GNR7 and 4GNY9.

Sustained filtration performance

Under continuous operation the microglass media maintains its 5 micron rating across the full 147 cfm flow range. The element is designed for steady particulate capture rather than short-burst spikes. ISO 8573 compliance indicates consistent air quality delivery over extended duty cycles. Regular monitoring of pressure drop will indicate when the element requires replacement.

Compatibility checks before ordering

Verify that your filter housing accepts the SPEEDAIRE EF series element and matches the listed Grainger cross-references. Confirm the system operates within the 147 cfm maximum flow limit to avoid excessive pressure loss. Check that the 5 micron rating suits your application's air quality requirements. Note the California Proposition 65 warning regarding chemicals known to cause cancer and reproductive harm.

Questions about this item

How much airflow does the 5 micron pre-filter element handle continuously?

The element is rated for a maximum flow of 147 cfm, so it will pass that volume of compressed air while trapping particles down to five microns.

Which existing filter housings accept this SPEEDAIRE 4GPG2 element?

It fits the Grainger part numbers 35GN50, 4GNR7 and 4GNY9, so any housing using those part numbers will accept the microglass cartridge.

Will this ISO 8573-rated pre-filter work with older compressor lines in the shop?

Yes, the element meets ISO 8573 standards and its 147 cfm capacity matches many legacy systems, provided the housing matches the listed Grainger part numbers.
