Espar AM3-D4L w/Installation Kit

The Espar Airtronic AM3-D4L is Eberspaecher's most advanced Generation 3 diesel air heater — engineered for commercial-grade performance in vans, trucks, and campers that run on diesel.

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

Why the AM3-D4L?

• Built-in altitude adjustment — works up to 5,500m / 18,000 ft with no additional module required
• Runs on diesel — draws directly from your vehicle's existing fuel tank
• EasyStart Pro Controller included — timer-based scheduling right out of the box
• Universal Fuel Pick-Up Pipe included
• 2-year / 2,000-hour warranty — backed by Eberspaecher's manufacturer warranty
