See For Yourself
Don’t Take Our Word For It — Watch
Three short videos: where VoltAire units are built, what goes into them, and how fast they are to service in the field.
Made in America
Inside the U.S. factory where every VoltAire unit is built and tested.
Quality, Start to Finish
What goes into a cabinet cooler that lasts — materials, assembly, and testing.
Easy to Service
Built for technicians by technicians — see how fast routine service goes.
Replacement Compatibility
Every VoltAire unit matches the capacity, voltage, and NEMA rating of the OEM unit it replaces. Many are bolt-for-bolt drop-ins — others may need an adapter plate or minor cabinet modification.
Direct Drop-In
Same bolt pattern, same cutout. Unbolt the old unit, bolt ours up — no modifications needed.
T2002 → AN02
T2904 → AT04, AT06
N3606 / N3608 → AN06, AN08
T4306 / T4308 / T4310 → AT08, AT10
With Adapter Plate
VoltAire adapter plates bridge different cutout sizes. Field-installed — order separately.
T4306 / T4308 → AN06, AN08
T5012 → AT08, AT10, AT12
T5319 / T6222 → AT08 – AT19
N4312 → AN06, AN08
Capacity & Voltage Match
Same cooling capacity and voltage but different footprint. May require cabinet cutout modification.
T1501 / N1601 → AN01
N2102 → AN02
N2804 → AN04
T5319 → AT19 (cabinet mod)
Always verify cutout dimensions before ordering. Use our cross-reference tool to confirm compatibility for your specific model.

“A McLean unit on one of our automation lines went down and we needed a replacement fast. Not only was it in stock, it was cheaper than the other options we found online. Bookmarked VoltAireCooling.com for any future needs.”
Robert C.
Bridgeton, NJ
“The installation is super fast and easy, the unit is a direct replacement and is a perfect fit. The bolts lined up perfectly — we did not have to drill any new holes. All in all a fast and easy procedure.”
James T.

“VoltAire was the perfect solution — not only was the enclosure I purchased much lower than the OEMs I researched, but the customer service was top notch. I called and got Justin on the phone to walk me through my questions.”
