Product context
Overview
Airrex AH-800i is a larger diesel infrared heater for high-volume temporary spaces and professional working areas. It is intended for bigger halls, workshops, warehouses, event tents, and operational spaces where the smaller AH models may not provide enough coverage.
This is a planning-led product. The right heater choice depends on the structure, air volume, insulation, openings, weather exposure, operating hours, and the acceptable fuel and ventilation arrangement. It should not be sold as a simple impulse product without checking the site context.
Use the heating calculator, or tell us the space and the target temperature. Your specialist sizes the AH-800i and sends the safety documentation with the quote.
