Description
Product Overview
The Dcfairfan Radon Manometer is engineered for professionals who need a quick visual confirmation that a radon mitigation system is active. Constructed from durable, impact‑resistant housing, the device houses a sealed column of non‑toxic fluid that rises and falls with pressure changes. Its uniquely molded curved scale aligns perfectly with standard radon pipe diameters, eliminating the need for custom adapters. Dimensions are compact at 3.9 x 8.6 x 1.1 inches and the unit weighs only 2.89 ounces, making it easy to mount in tight spaces. The manometer is rated #23 in the Manometers subcategory on Amazon, reflecting strong market acceptance.
Usage
Designed for residential and commercial radon mitigation installations, this manometer is used during system commissioning, routine maintenance, and troubleshooting. Technicians attach the included tubing to the radon pipe, secure the unit with the two supplied screws, and observe the fluid levels. Uneven levels indicate active suction, confirming the fan is operating; a level line signals a potential failure. The device is also suitable for educational demonstrations in industrial‑scientific training programs.

FAQ
Can this manometer measure radon concentration?
No. The device is intended solely to verify that the radon mitigation system is operating, not to measure radon levels in the air.
Is the fluid safe if the unit is accidentally broken?
Yes. The fluid is non‑toxic and complies with safety regulations, so accidental spillage poses no health risk.
What pipe sizes does the curved scale fit?
The scale is molded to accommodate the most common radon system pipe diameters (typically 1‑inch to 1.5‑inch PVC).
How often should the manometer be inspected?
We recommend a visual check during each system maintenance visit to ensure the fluid level remains consistent and the housing is intact.
Does the kit include a warranty?
Yes, Dcfairfan offers a one‑year limited warranty covering manufacturing defects and material failures.
