Espar AM3-B4L - FORD TRANSIT - Petrol

Built for Ford Transit owners who demand more than a space heater — the Espar Airtronic AM3-B4L is a commercial-grade petrol air heater engineered to perform in the real world, season after season.

With a 5,000-hour brushless motor, built-in altitude compensation up to 18,000 ft, and a complete Transit-specific installation kit included, this is the heater serious van builders and fleet operators reach for.

Why the AM3-B4L?

• 4 kW output — powerful enough to heat a full-size cargo van or camper in sub-zero temps
• Brushless motor — extended 5,000-hour service life and noticeably quieter operation than previous generations
• Built-in altitude adjustment — works up to 5,500m / 18,000 ft with no additional module required
• Improved fuel metering pump acoustics — runs cleaner and quieter than the outgoing model
• Runs on gasoline/petrol — draws directly from your Transit's existing fuel tank
• EasyStart Pro Controller included — timer-based scheduling right out of the box
• Muffler Kit included — quieter exhaust, no extra purchase needed
• 2-year / 2,000-hour warranty — backed by Eberspaecher's manufacturer warranty
