White cylindrical coalescing filter element with microglass media for 15 cfm airflow

SPEEDAIRE

SPEEDAIRE 4GPE1 Element Coalescing Filter 1 Micron 15 CFM

SKU CH-W2W2-KC75N

Removes oil and water aerosols from compressed air at 15 cfm using a 1‑micron microglass coalescing element

  • Removes oil and water aerosols with 1 micron coalescing media
  • Delivers 15 cfm maximum flow for compatible compressed-air systems
  • Microglass element material captures fine particles for cleaner air output
  • Meets ISO 8573 standards for compressed-air purity classification
  • Fits Grainger part numbers 35GN24 4GNN6 4GNW8 for direct replacement

1 Micron Coalescing Filter Element

The SPEEDAIRE 4GPE1 is a general-purpose coalescing filter element rated at 1 micron for compressed air systems. It removes oil and water aerosols to protect downstream pneumatic tools and equipment. The microglass media targets fine particulates and liquid carry-over in air lines.

ISO 8573 Compliance and 15 CFM Flow

This element meets ISO 8573 standards for air purity classes and supports a maximum flow rate of 15 cfm. In normal operation it maintains low pressure drop while capturing sub-micron contaminants. The microglass construction resists saturation for consistent filtration performance.

Compatible Grainger Housing Series EF

The filter fits Grainger part numbers 35GN24, 4GNN6 and 4GNW8 within the EF series housings. It installs directly into existing filter assemblies without additional adapters. The design frees up maintenance time by using a standard drop-in replacement format.

Questions about this item

How do I install the SPEEDAIRE 4GPE1 coalescing filter element, and what step is often missed?

Shut off and depressurise the air line, remove the housing bowl, slide the used element out, insert the new 1‑micron microglass element with the flow arrow pointing downstream, reinstall the bowl and torque to the housing spec, then slowly repressurise and check for leaks.

What maintenance or replacement will the SPEEDAIRE 4GPE1 element need over time?

Replace the element when the pressure drop across it reaches the housing’s change‑out indicator or at the interval set by your compressor manufacturer; the microglass media cannot be cleaned and must be swapped for a new 4GPE1.

What limit appears first on the SPEEDAIRE 4GPE1 when running continuously at full flow?

The 15 cfm maximum flow rating is the first constraint; exceeding it raises differential pressure rapidly and shortens element life, so size the housing and upstream compressor to stay at or below 15 cfm.
