Quest Muffler Kit - Quest HI-E Dry 195 and HI-E Dry 120

Exhaust Muffler Kit for Quest Hi-E Dry 195 & 120 Dehumidifiers

This kit addresses noise, not airflow routing: it's a muffler assembly that mounts to the compatible dehumidifier's exhaust path to reduce operating noise, which matters when a unit runs in or near an occupied space rather than an isolated mechanical room.

It's sized for the Quest Hi-E Dry 195 and Hi-E Dry 120 portable models and includes the muffler assembly along with the mounting hardware needed to install it.

Key Features & Benefits

• Muffler assembly — dampens operating noise from the dehumidifier's exhaust path, rather than affecting airflow volume or direction.
• Complete mounting hardware — everything needed to attach the muffler assembly to the compatible unit is included.
• Reduces noise in occupied spaces — useful where the dehumidifier runs in or adjacent to a space where people are working, rather than an isolated mechanical closet.
• Model-specific fit — sized specifically for the Hi-E Dry 195 and Hi-E Dry 120 portable units.
• Simple bolt-on installation — designed to mount onto the existing exhaust path without modifying the unit itself.

Who Should Use This

This kit is for operators running a Quest Hi-E Dry 195 or Hi-E Dry 120 in or near an occupied workspace where operating noise is a practical concern, such as a shared building, a residential-adjacent facility, or a space where staff work for extended periods near the unit.

About Quest

Quest is a Therma-Stor brand. It focuses on commercial dehumidification. Therma-Stor is headquartered in Madison, Wisconsin. It's the same parent company behind the Anden brand. Therma-Stor has built dehumidifiers and environmental-control equipment for decades. Quest specifically targets commercial and industrial moisture control. Think indoor cultivation, food production, and commercial buildings. That's a different focus than residential basement units. Many overhead models use the company's patented M-CoRR design. M-CoRR stands for multi-coil refrigeration. The design recycles heat pulled from the air. That happens during dehumidification itself. It improves energy efficiency as a result. It also cuts heat sent back into the room.

Frequently Asked Questions

What does this Muffler Kit actually do?

It dampens operating noise from the dehumidifier's exhaust path. It doesn't change the unit's airflow volume, moisture removal capacity, or ducting configuration -- its only job is reducing sound.

Which Quest models does this kit fit?

It's designed for the Quest Hi-E Dry 195 and Hi-E Dry 120 portable dehumidifiers. Confirm your exact model before ordering, since the muffler assembly is sized to these specific units' exhaust openings.

How is this kit installed?

The kit includes the muffler assembly and the mounting hardware needed to attach it, designed as a bolt-on addition to the existing exhaust path. Most facility maintenance teams comfortable with basic mechanical installation should be able to complete it without specialized tools.

Does adding a muffler reduce the dehumidifier's moisture removal performance?

No, the muffler kit addresses noise at the exhaust path and isn't designed to restrict airflow or affect the unit's rated moisture removal capacity. If you notice reduced performance after installation, check that the muffler is seated and mounted correctly per the installation guide.
