1-Micron Coalescing Filter Element

The SPEEDAIRE 4GPG3 is a coalescing filter element rated at 1 micron for general-purpose compressed air systems. It removes oil and water aerosols using a microglass media designed to meet ISO 8573 standards. The element handles a maximum flow rate of 147 cfm to protect downstream pneumatic equipment.

Check housing series and flow requirements

Verify that your filter housing uses the EF series and that the 147 cfm capacity matches your compressor output. Confirm the thread size and overall dimensions against the existing element to ensure a proper seal. The unit is compatible with Grainger part numbers 35GN51, 4GNR8, and 4GNZ1 for cross-reference purposes.

Fits EF series housings for air preparation

This element installs directly into compatible EF series filter housings to deliver clean, dry air to tools and machinery. It frees the air stream from fine oil mist and water droplets that can damage actuators and contaminate finishes. The microglass construction maintains low pressure drop while capturing sub-micron particles.
