GUARDIAN FA
THE HIGH END OF THE MARKET, ENGINEERED 
TO YOUR ENVELOPE.
When a hyperscale AI hall needs 725 kW per unit at a footprint, a discharge geometry and a 
controls spec nobody catalogs, this is the platform. Every Guardian FA is engineered to 
spec — coil bank, fan count, casing, controls — and still ships as one factory-piped,
run-tested package.
