Filtration Technology

IQAir GC MultiGas half-cut

1. Micro-Particle Filtration  Utilising the high-efficiency GC HEPA Pre-Filter, the system adeptly captures substantial particle pollution such as dust, traffic emissions, pollen, pet dander, dust mites, and mould allergens. The pre-filter in the GC MultiGas air cleaner boasts a high-capacity mini-pleat design, featuring solvent-free separators and constructed without harmful CFCs.

This pre-filter employs a non-woven glass microfiber media, exhibiting an impressive efficiency rate of 99% at 0.3 μm (class H11). Its expansive surface area, combined with the impeccable, leakage-free design characteristic of all IQAir air purifiers, safeguards the fan and subsequent filters from the impact of larger particle pollutants. This proactive approach ensures prolonged filter life and sustained, reliable performance.

2. Odour and Gas Elimination  The GC MultiGas Cartridge-Filter Set comprises four meticulously engineered gas and odour control filter cartridges, working synergistically to filter an extensive array of gaseous and chemical substances. Powered by advanced filtration technology, the GC MultiGas effectively neutralizes a broad spectrum of gaseous pollutants and odours, including volatile organic compounds (VOCs). This exceptional performance is made possible through a 5.4 kg wide-spectrum media blend of granular activated carbon and KMnO4 impregnated alumina.

The GC Filter Cartridge Set's substantial surface area facilitates a high airflow rate. When combined with the unit's leak-proof construction, the GC MultiGas stands as the most efficient air purifier in the realm of odour, chemical, and gas removal. Its unparalleled ability to neutralize odorous and chemical compounds renders it a superior choice for environments demanding uncompromising air quality.

3. Fine Dust Removal  The GC Post-Filter Sleeve Set consists of four electrostatically charged fibre filters. These post-filter sleeves excel in capturing fine dust particles, ensuring a comprehensive filtration process. This meticulous filtration not only eliminates fine dust but also effectively removes activated carbon and chemisorption abrasion particles.

IQAir GC Series’ cartridges operate cohesively, addressing a wide spectrum of moderate gas phase removal requirements in both residential and commercial settings. This integrated approach guarantees a superior level of indoor air quality, making it an optimal choice for environments where fine dust elimination is paramount.

GC Post-Filter Sleeve Set provides the final filtration stage of the GC MultiGas. The four post-filter sleeves are electrostatically charged fiber filters that capture fine dust particles. This eliminates activated carbon and chemisorption abrasion particles. Each of the cartridges of the IQAir GC Series operate in unison to meet almost any moderate gas phase removal needed in residential or commercial environments.
