General-purpose coalescing filter element

The SPEEDAIRE 4GPF4 is a new general-purpose coalescing filter element rated at one micron. It is intended for compressed-air systems that must remove oil and water aerosols from the air stream. The element suits maintenance teams and plant engineers who need a direct replacement for compatible filter housings.

1-micron rating at 88 cfm maximum flow

The single specification that determines fit is the one-micron filter rating combined with a maximum flow rate of 88 cfm. If the system demands finer particle capture or a higher flow capacity, this element will not meet the requirement. Buyers who need sub-micron filtration or flow rates above 88 cfm should select a different grade.

Compatible Grainger part numbers

The element crosses to Grainger part numbers 35GN40, 35GN44, 4GNP9 and 4GNY2, simplifying identification during reorder. It is built to the ISO 8573 series standard, so it supports air-quality classes defined by that specification. The microglass media handles both oil and water aerosols in a single cartridge.

Questions about this item

What does the 88 CFM rating mean when this filter is installed in a compressed-air system?

It indicates the maximum airflow the element can handle while maintaining its 1-micron coalescing performance for oil and water removal.

Which standard governs the 1-micron rating and what does it cap in practice?

ISO 8573 defines the purity classes; the 1-micron rating limits solid particles and liquid aerosols to that size in the compressed-air stream.

What housing or mounting dimensions does this element require to fit?

It is designed as a direct replacement for Grainger part numbers 35GN40, 35GN44, 4GNP9 and 4GNY2 in Series EF filter housings.
