Gelair Air-conditioning Blocks are a biodegradable gel containing tea tree oil. When the air conditioning unit operates normally, the gel vaporises in the air, releasing the tea tree oil. The tea tree oil controls the mould and bacteria in the air handling units, ducts and rooms serviced by the air-conditioner.
Gelair Solution is a concentrated solubilised solution of tea tree oil. Mixed with other cleaning agents, this product is great for cleaning cooling coils in air handling units, ducts and other contaminated surfaces.
