Product description
QUEST 706 50-HZ Dehumidifier: product details and use
With up to 335 litres per day at 26.7 °C / 60% RH, the Quest 706 provides reliable humidity control – even in large grow rooms. Its patented multi-coil technology maximises efficiency and allows continuous operation without loss of performance.
Energy efficiency and power supply
At 3.4 litres per kWh, the Quest 706 is extremely efficient. Despite its high output, power consumption is around 4,150 W (18.6 A), connected directly to 230 V / 50 Hz, making it ideal for professional environments. A buck-boost transformer is optional for other voltages.
Robust quality and filter technology
The MERV‑13 air filter effectively removes dust, pollen, mould spores and bacteria – essential for clean air in grow and storage areas. The housing is heavy-duty, with integrated carry handles, and can be floor- or ceiling-mounted.
Flexible installation & control
The 706 supports both plug-and-play and permanent hard-wiring. For targeted air distribution, it can be fitted with inlet and outlet duct kits. Humidity is controlled via external controllers (e.g. DEH 3000R or a hygrostat via the 24‑V terminal block).
