Fit Details
Fits After ModificationSame cooling capacity and voltage as the N280426G151 — generally considered a match, just not bolt-for-bolt. The cabinet cutout differs by a small amount, so a quick trim with a sawzall (or similar tool) gets the VoltAire AN04RQW10 into place. Minor field work, no adapter plate required — routine for any installer. Call (844) 925-5668 if you'd like us to walk through the trim before you order.

The two manufacturer drawings are centered on each other for visual comparison only, because a shared mounting reference between the two units has not been verified. Verify every opening against your actual unit before any cutting or mounting. This comparison is a visual guide, not a cutting or drilling template. Openings can vary with voltage and production run — verify against your actual unit before any cutting or mounting, and follow the manufacturer's installation template.
