Cotton Canvas Heater Ducting
The material of choice for cold weather helicopter users, because canvas is the most durable.
Dragging ducting across ice is really hard on ducting. Canvas holds up better than PVC.
- Standard Duct for the EC Series heaters.
- Also works with Jumbo Models.
- Metal J-Lock collars allow quick assembly and knockdown.
- Extra-durable cotton canvas ducting.
- For high abrasive application.
