The quality is not clearly visible on the product photos, the main difference is inside. LF Bros Diesel Air Heaters are using the same high-quality parts as the most expensive brands like Eberspacher – Japanese glow plugs Kyocera, thick quality aluminum heat exchangers, high-temperature resistant plastic parts, etc.
The main strength is in the electronic components. LF Bros developed its own microprocessor controlled units with multitasking and automatic checking of values from all sensors. Also, the firmware runs the cleaning procedures to avoid creating carbon deposition and therefore increases the lifetime of the unit. With the advanced overheating protection, this makes the LF Bros heaters one of the safest Diesel Air Heaters on the market.
In contrary, most of the cheap Chinese brands are using low-quality glow plugs, heat exchangers with thin walls, plastic molded parts of low quality (harmful substance will be released after being heated), half developed electronic without safety procedures and firmware full of issues and bugs. Do not get caught buying cheap copies.
