Air Heaters

Backer Marathon air heaters feature an open coil of high temperature resistance wire electrically isolated in a stainless steel sheath. Because the air being heated passes directly over the resistance wire, maximum heat transfer efficiency is achieved. Backer Marathon brand air heaters are used for heat staking, plastic welding, laminating, drying, heat sealing, and any other operation where air needs to be heated up 1000°F.

1/2” and 3/4” diameters are standard with other sizes available. Several 1/2” diameter air heaters are in stock for same day delivery. Options such as male and female fittings for inlets and outlets, thermocouples to monitor outlet temperature, and pin connectors are available.
