Quest 506 High-Efficiency Dehumidifier

Description

Quest 506 Overhead Dehumidifier – Built for Big Demands

When large-scale moisture control is mission-critical, the Quest 506 delivers. Engineered in the USA for high-performance environments, it’s one of the most capable overhead dehumidifiers available—designed to protect what matters most in commercial grow rooms, military storage, warehouses, and expansive indoor facilities.

Power Meets Practicality

With its high pint-per-day capacity and efficient design, the Quest 506 doesn’t just fight humidity—it dominates it. Whether you’re growing, storing, or safeguarding, this unit keeps moisture levels in check to prevent mold, mildew, corrosion, and other costly damage.

Available in two models:
• 230V (Model 4046300) – NEMA 6-20P plug
• 277V (Model 4046310) – NEMA L7-20P plug

Smart, Space-Saving Installation

Its overhead design frees up valuable floor space, and it operates seamlessly between 56°F and 95°F. A built-in gravity drain hose makes moisture disposal easy—outdoors or to a tank. Need ducting? Optional intake and exhaust kits make it adaptable to your layout.

High-Efficiency M-CORR Technology

Quest’s patented M-CORR tech uses multiple recovery coils to maximize efficiency. It pulls 30% more water than typical dehumidifiers and uses significantly less energy, producing less heat and lowering your energy footprint.

Designed for Control and Compliance

Maintain ideal humidity levels that preserve product quality and facility integrity. Plus, the Quest 506 is Title 24 compliant, drawing only 11 amps and delivering up to 8.1 pints per kilowatt hour—making it one of the most efficient high-capacity systems on the market.
