An Oil-Free Heater, also known as an non oil-filled heater, oil-filled radiator, is a common form of convection heater used in domestic heating. Oil-free heaters usually do not have fans to blow the heat into the room and office . The lack of a fan in an oil-free heater is what makes it silent and great.  

so oil-free heaters are perfect and weightlight.

welcome to OEM.
