What is Radon Away RP145 Radon Mitigation Fan?

RadonAway RP145 is a well-accepted radon mitigation fan that intends on working as an active soil depressurization system for plummeting unsafe radon gas. This mitigation fan is an ideal choice for both new constructions as well as retrofit radon systems.

How does RadonAway RP145 Radon Mitigation Fan work?

This RP Series Radon Mitigation Fan can be mounted both indoors as well as outdoors. One should follow the EPA recommendations for choosing the fan location. The fan can be directly mounted on the system pipe or be fastened to a support structure by the means of any non-compulsory mounting bracket. Mount the fan vertically with the outlet facing upwards. Assure that the unit is at level and plumb. Make sure that the radon mitigation fan doesn’t contact any building surface when mounting directly on the system pipe. This avoids the vibration noise if any.

Also make sure to seal all the major openings, cracks, or any sort of penetrations in the building slab while installing an active soil depressurization system for radon reduction.  And fan sizing for the retrofits may require professional designing and diagnostics.

Frequently Asked Questions for Radonaway RP145 Radon Mitigation Fan: FAQs

Here are the answers to the frequently asked questions about radon fans, particularly the RadonAway RP145. We hope this will help you make a better purchase decision. Do let us know in the comments below if you have more queries or suggestions.

Q1.What are the symptoms of radon on my property?

Since radon is a colorless, odorless, and tasteless gas, it is harmful to your health in the long run. Radon is an invisible enemy, as it is also radioactive in nature. It slowly starts affecting your well-being, and the signs of exposure include the following:

  • Chest pain
  • Wheezing
  • Hoarseness
  • Persistent coughing
  • Shortness of breath
  • Coughing up blood
  • Frequent infections such as pneumonia and bronchitis

Radon is chemically inert, so to find its presence, you can only test your surroundings and determine the levels.

Q2.Does radon get worse over time?

It certainly does.

Accumulation of radon in your property can be very harmful if you do not invest in a mitigation system. EPA recommends testing the radon levels at least two times over a year as the figures keep fluctuating from time to time. So it would be best if you remain careful.

Q3.At what levels should radon be mitigated?

Although no radon levels are safe, EPA advises that levels above 4pCi/L should be mitigated. After smoking, radon is the second biggest cause that leads of lung cancer in The States. Therefore, you must make sure you are keeping yourself and your loved ones safe and healthy.

Q4.How do radon fans help?

As the name suggests, the radon (mitigation) fan helps vent the gas out of your property. It connects to the suction pipe to exhaust the gas from underneath the house and discharge it into the outside air while at the same time, creating negative pressure below the slab.

Q5.How to choose the vent pipe size?

This has a simple formula:

If CFM is under 40, use a 2-inch diameter pipe size

If CFM is under 70, use a 3-inch pipe size

If CFM is over 70, use a 4-inch pipe size

Q6.How much does a radon mitigation fan cost?

A 4-inch radon fan featuring energy-efficient and ultra-quiet operation along with 166 CFM, may cost you anywhere between $100 and $140.  The price may usually vary depending on several factors like brand, design, CFM, size, and construction material. 

Typically, these start from as low as $100 and go up to around $800. 

The complete mitigation system may be even costlier, but that is an entirely different thing. A fan-like RadonAway RP145 comes in very cheap and guarantees 5 to 10 years of performance.

Q7.Is RadonAway a reliable brand?

RadonAway has been providing home and business owners with durable fans intended exclusively for radon mitigation applications. They are in the industry for the past three decades. Most homes in the United States are highly likely to have RadonAway fans. It is the world’s leading manufacturer and supplier of radon mitigation products. 

Indeed, it is the choicest brand among homeowners and business owners. 

Q8.Can I install a radon mitigation fan myself? 

Professional installation may be expensive but is usually recommended by a lot of manufacturers to ensure there is no violation or chance of any slip-ups. However, you can also install a mitigation fan all by yourself at just half the cost. But, make sure you first check the warranties and put up only a DIY system by yourself.

Q9.Why is my radon fan so loud?

Radon mitigation fans wear out with time, and that is when they get noisy. However, it is also possible that the bearings are going bad and may demand some lubrication or replacement. So that is again a major reason why the radon fan might get loud.

Q10.When should a radon fan be replaced?

First, when the fan is getting loud, or you notice unnecessary vibrations. Second, it has been quite some time (around 5 to 10 or 20 years) since you installed the fan, and its lifespan is exceeding.

These are two main reasons that your system needs to be checked, and the fan requires replacement. Radon fan runs all the time, and they need special attention all year round.

Q11.Do radon fans run continuously?

Generally, the answer is yes.

Radon fans run 24×7 to remove dangerous gas from the area in which they are installed. Always operate your fan and make sure the levels are maintained. Plus, it is very much cost-effective to run the fan continuously due to its construction and design. Therefore, it is best to keep the fan running even if you are on an extended vacation so that when you come back, the indoor air quality is not compromised.

Q12.What are the benefits of RP145?

The RadonAway RP Series Fans provide superb performance and are ideal for general ventilation purposes. The RP145 model is ultra-quiet and attractive. It has a low-profile design, is thermally protected, offers higher airflow, and is excellent for residential and commercial usage.

Q13. How long does the RP 145 radon fan last?

Well-maintained fans easily last for about 10 to 15 years at a stretch. However, manufacturers like RadonAway warrant only professionally installed radon fans for five years from the date of installation, typically against mechanical failure.

Q14. Is this fan approved for exterior use?

The RP145 radon fan is excellently designed for superior performance. Since it is quiet and also moisture-resistant, the model can be used both inside as well as outside the house.

Q15. Can I replace a radon fan myself?

If you are handy with the process of replacement, you can surely get rid of your old fan or system. However, by installing a new unit like RP145, the DIY case may not carry the same warranty claims as others. RadonAway does not honor their warranty unless a licensed installer installs the unit, so take care of that as well.
