Prometheus PCG38FLW312-20G-AB 50mm x 50mm x 20mm 12V DC Blower
50 mm x 50 mm x 20 mm · 10-13.5 V DC
centrifugal fan for high-impedance enclosure cooling. Full datasheet, P-Q curve and dimensional drawing available through an RFQ.
Overview
Application and specification highlights for Prometheus PCG38FLW312-20G-AB 50mm x 50mm x 20mm 12V DC Blower.
The Prometheus PCG38FLW312-20G-AB is a 12V DC centrifugal blower designed for high-impedance electronics enclosures and compact ducted cooling. The 50mm x 50mm x 20mm frame balances airflow capacity with installation footprint. Nominal supply is 12V DC, with an operating input window of 10-13.5V DC. Rated speed is 12,000 RPM.
At rated input, maximum free-air delivery is 9.2 CFM and peak static pressure is 37.2 mmH2O. Acoustic output is rated at 58.5 dB(A).
Build details include IP55 sealing available as a configuration option. Operating temperature range spans -55°C to +85°C. The model is supplied as a drop-in form-fit replacement for the legacy J38FLW312-20G-AB designation.
