AC.100.3850 Electric AC Compressor 12V/24V DC 20cc 850W R134a

How we label data. Confirmed values are read from supplied stock and the manufacturer’s published technical data; reference values are published family designations shown for identification only; anything not published is withheld rather than guessed.

A conventional A/C compressor is driven by the engine belt; an electric split compressor is driven by a DC motor instead. That is what makes the AC.100.3850 electric AC compressor the standard solution wherever there is no belt drive at all — an electric car AC compressor for EV platforms, an RV air conditioner compressor that keeps the cabin cool with the engine off, and a truck cab electric AC compressor for sleeper cabs and buses.

The AC.100.3850 is a 20cc electric split compressor with a rated power of 850W and a rated cooling capacity of 2600W. It runs on R134a refrigerant with POE68 compressor oil and takes a 24V DC supply across an 18–32V input range. As a universal automotive AC electric compressor it is matched to the vehicle by voltage, capacity and mounting — not by a make and model list — so we confirm voltage and layout before quoting.

The same family includes the AC.100.3851, a 12V variant rated 600W at 2300rpm, and an ACTECmax electric compressor designation for the identical hardware. If you are unsure which variant your system needs, send the old compressor label and we will confirm the match in writing.
