The DeLonghi Pinguino PAC AN112 Silent is a premium portable air conditioner designed for powerful cooling with minimal noise — making it perfect for medium to large indoor grow setups that require as little noise as possible. Ideal for when discretion is a priority, it’s equipped with “silent” technology that significantly reduces sound levels (as low as 50dB) — as well as Real Feel technology, which intelligently balances temperature and humidity for optimal plant health at all stages. Additional features include a BioSilver air filter to combat mold and bacteria, three fan speeds, dehumidifier mode, and a programmable 24-hour timer. Energy efficiency with an A+ energy rating, it’s an eco-friendly option that helps reduce the environmental impact of your grow. For smaller setups where silence is key, check out the PAC N90 EcoSilent model for ultra-quiet operation in a compact design. If you don’t need a whisper quiet operation, the PAC N82 ECO is a great small-scale choice.
