With Active coal
RMF Air Conditioners can be filled with a combination of Z-R gel and active coal. The active coal will eliminate oil vapour and the smell, it will also prevent the Z-R gel from being contaminated with this oil damp.
Z-R gel is a non-toxic non-carcinogenic desiccant with excellent moisture uptake and colour indication for saturation. The active coal is also a competely safe and harmless substance and is not a health risk.
