Prevost ALTO 4 Compressed Air Filter / Water Separator — 3/4" & 1" FNPT
The Prevost ALTO 4 compressed air filter removes bulk water, condensate and pipe scale from your air line before it reaches tools, dryers or point-of-use equipment. ALTO 4 is the large-body size in the Prevost ALTO air-preparation range, covering 3/4" and 1" FNPT ports — the sizes above where the Prevost ATU series stops.
A machined aluminum body and metal-guarded bowl handle real shop pressures, and the push-button drain lets you dump collected condensate without tools. The modular ALTO 4 body stacks with the matching ALTO 4 regulator and lubricator, so you can build a 3/4" or 1" filter-regulator-lubricator train from individual modules.
