Cooling and Heating

Most Eco-Air air conditioners have both cooling and heating capabilities.

Plasma Technology

Eco-Air's Plasma Dust Collector can generate an ionization zone. The air is converted to plasma as it passes the high voltage ion generator. 95% of dust, smoke and pollen particles are attracted to the electrostatic filter. Ideal for those who are looking for clean, fresh pollen free air. This is a favourite with hay fever sufferers and smokers.

All split air conditioning units contain F Gas and is govern by F-Gas regulations. All F-Gas units must be handle by qualified F-Gas engineers.
