About this product
This is a Ballmers 69HAU3 Hubbell Furnas Air Compressor Pressure Switch with Unloader, featuring a durable metal housing. It comes preset to 30-40 PSI but can manage a total pressure range from 15 PSI cut-in to 60 PSI cut-out. The switch supports multiple voltage configurations (120V/240V single phase, 240V/600V three phase, and DC voltages) and has an IP54 international protection rating, indicating resistance to dust and splashing water.
Our take
This Ballmers 69HAU3 pressure switch is a robust and versatile component for any air compressor, especially given its metal housing construction and IP54 rating. The preset 30-40 PSI range is standard for many smaller compressors, but its ability to handle a total pressure range from 15 to 60 PSI makes it adaptable. I appreciate the included unloader valve, which is crucial for efficient compressor startup and reducing motor strain. Its wide voltage compatibility, supporting both AC and DC, single and three phase, is a huge plus, making it suitable for a variety of setups. Just ensure the thread size and unloader bore match your existing system for proper installation.
