Quest New 506 High-Capacity Dehumidifier, 208V or 230V

Large-scale commercial, industrial, and agricultural facilities generate moisture loads that smaller dehumidifiers simply can't keep up with, and the Quest 506 is built for that scale. It removes up to 500 pints of moisture daily at 9.2 pints per kWh, using patented M-CoRR technology to recycle heat and improve energy efficiency.

It runs on flexible 208V or 230V power, with integrated suspension points for overhead or floor mounting and auto-restart after power outages, so operation resumes automatically once power is restored.

Frequently Asked Questions

How many pints of moisture does this unit remove per day?

It removes up to 500 pints of moisture per day at 9.2 pints per kWh, sized for large-scale commercial, industrial, and agricultural spaces. Patented M-CoRR technology helps it reach that output while keeping energy use in check.

What does MERV-13 filtration capture?

It captures dust, mold spores, bacteria, and some viruses as air passes through the unit. That level of filtration helps protect both the dehumidifier's internal components and the air quality in the space it serves.

What power supply does this unit use?

It runs on flexible 208V or 230V power, giving installers some latitude in matching the unit to existing electrical service. Quest also offers a 277V version of the New 506 for facilities that need it.

What happens after a power outage?

The unit auto-restarts once power is restored, so it resumes dehumidifying without needing someone to manually turn it back on. That's especially useful in facilities that aren't staffed around the clock.

Who do I contact for service or parts?

Reach out to Quest support with your unit's model and part number for service or replacement parts. Keeping your purchase documentation on hand speeds up that process.
