SPEEDAIRE 4GPD9 Pre-Filter Element

The SPEEDAIRE 4GPD9 is a particulate pre-filter element rated at 5 microns with a maximum flow rate of 15 cfm. It uses microglass media and meets ISO 8573 standards for compressed air quality. This new component suits maintenance crews and facility engineers who need clean air supply for pneumatic tools and systems.

Installation notes and common issues

The element fits compatible Grainger housings including part numbers 35GN19, 35GN23, 4GNN5 and 4GNW7. Installation is straightforward: depressurise the system, remove the old element, seat the new one squarely and reassemble the bowl. The most frequent problem is cross-threading the bowl or reusing a worn seal, which causes bypass leaks and pressure drop.

Critical specification: 5-micron rating

The 5-micron particulate rating is the single figure that decides fit-for-purpose. It captures fine dust and aerosols before they reach downstream dryers or point-of-use filters. If your process requires coarser or finer filtration — for example, oil aerosol removal or sterile-grade air — this element will not meet the requirement.

Questions about this item

How can I confirm the pre-filter is performing to its 5 micron rating after installation?

Monitor downstream air quality and pressure drop; a steady 15 cfm flow with clean output indicates the microglass element is trapping particulates to the ISO 8573 standard.

What comes with the SPEEDAIRE 4GPD9 element and what must I source separately?

The box contains only the 5 micron microglass pre-filter cartridge; housing, brackets, seals and any adapters required for your compressor line are sold separately.

Which SPEEDAIRE pre-filter version matches my existing EF-series housing — 35GN19, 35GN23, 4GNN5 or 4GNW7?

Cross-reference the Grainger part number stamped on your current housing; the 4GPD9 element fits all four listed numbers, so choose the one that matches your installed unit.
