Airrex AH-300i — event & marquee heater

Airrex AH-300i is a diesel infrared heater for larger working areas, temporary spaces, and event support. It sits above the AH-200i in the launch range and is better suited to bigger covered spaces, event tents, workshops, halls, terraces, and warehouse areas.

The product uses infrared heat, so it is useful where direct warmth is needed in a defined area rather than relying only on warm air circulation. It can support temporary structures and operational spaces where the heating plan needs to account for doors, wind exposure, ventilation, and footfall.
