Quest 700 by Quest – Full Throttle Humidity Control

Crush high humidity in high-capacity rooms

💬 Meet the Quest 700 - the top dog of dehumidifiers for large-scale grow rooms and commercial facilities. With a monstrous 332 litres/day capacity and ultra-efficient 3.9 L/kWh performance, this unit is built to dominate high humidity without draining your panel.

Running on 400V 3-phase power, it pulls less than 6 amps, freeing up space for the rest of your gear. Combine that with M‑CoRR patented coil tech, MERV 13 filtration, and onboard digital controls, and you’ve got elite environmental control - ready for anything you throw at it.

And yes, it’s engineered and assembled in the USA, not some flimsy import that quits when the RH gets real.

🔹 Key Features

🌪️ 332L/Day Capacity – Quest’s highest capacity unit, ideal for massive grow ops or drying rooms.

⚡ 3.9 L/kWh Efficiency – Industry-leading energy factor thanks to smart multi-coil engineering.

🔌 400V 3-Phase, 5.8A Draw – Serious power without hogging your panel or spiking heat output.

🛠️ How to Use It

This beast is hardwire only - built for pro installs. Mount it overhead using integrated lift points or run it on the floor if you’ve got the space. Set your RH target via the onboard controller or connect it to an external controller for full-facility integration. Auto-restart, dark mode, and filter alerts make it set-and-forget simple once it’s in.

🌟 Grow Guys Tips

Have a proper sparkie wire this one in - it’s 3-phase and deserves respect. Clean your MERV 13 filter regularly and keep the airflow clear to maintain peak performance. Need ultra-quiet operation? Hit the Quiet Mode to drop the decibels in sensitive zones.

🧃 Perfect For
