Pre-Filter Element 5 Micron

This SPEEDAIRE pre-filter element removes particulate matter from compressed air lines at a 5 micron rating. It is designed for pneumatic systems that require clean air supply before final filtration or point-of-use applications. The microglass media handles a maximum flow rate of 88 cfm within the EF series.

Microglass Media and ISO 8573 Standard

The microglass filter material provides consistent particulate capture while maintaining airflow across the rated capacity. Compliance with ISO 8573 supports air quality requirements for general industrial pneumatic equipment. The element fits Grainger part numbers 35GN39, 35GN43, 4GNP8, and 4GNY1 for direct replacement.

Prop 65 Notice and Compatibility Check

This product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm. Verify that your existing filter housing accepts the EF series element and that the 88 cfm rating matches your compressor output. Confirm the thread and dimension match the listed Grainger part numbers before ordering.

Questions about this item

How often should the 5 micron microglass element be replaced?

Replace the 5 micron microglass element when pressure drop across the filter indicates it is loaded with particulates; service intervals depend on air quality and the 88 cfm flow rate in your system.

What limits continuous operation at the 88 cfm rating?

The 5 micron microglass media traps particulates until the pressure differential reaches the change-out point; that differential is the first limit encountered during sustained flow.

Does the filter add noticeable noise or heat when running all day?

The passive microglass element adds no mechanical noise or heat; only a slight pressure drop occurs as air passes through the 5 micron media at up to 88 cfm.
