Fantech Pro and Pro Plus Series

On August 16, 2019, in cool products, news, by Nicole

Efficiency, quiet operation and ease of installation characterize both the PRO and PRO PLUS series. Both series are certified to the rigorous California Title 24 building energy code, as well as ETL/c-ETL, HVI, and Energy Star standards. The PRO Series operates at just 2.0 sones while the PRO PLUS is barely audible at 0.5 sones.

Sound levels are rated in sones where the lower the rating number, the quieter the fan. Typical economy fans are rated at about 4.0 sones or more. One sone is equivalent to the sound of a quiet refrigerator and a quiet bathroom fan will be rated at about 1.5 sones or less. This makes the PRO PLUS one of the most quiet bathroom fans on the market.

PRO Series offers three models with a ceiling grille and damper for airflow of 80, 100 or 150 CFM. The PRO 80 & 100 fans have a unique plug and play concept that allows you to add accessories such as a humidity sensor and LED light without changing the fan.

PRO PLUS has adjustable CFMs 80/90/110/140 with a ceiling grille, backdraft damper, humidity and motion sensor. It uses 6″ flexible duct. The product is provided with an adjustable 12-24″ bar hanger for ease of installation.

Recommendations for bathroom ventilation sizing can vary considerably between manufacturers and competing standards.  Some of the newer recommendations allow for low ventilation rates over long periods of time as opposed to the typical 8 air changes per hour. 

We prefer 8 air changes per hour as A MINUMUM and here is why:
When moisture is introduced into the bathroom it has an annoying tendency to get diluted into the entire air content of the space.  With low CFM (background) ventilation that moisture will eventually be exhausted, but in the meantime it will linger in the air and potentially condense on colder objects such as walls and fixtures.  Once it’s in liquid form on your walls it takes A LONG TIME to evaporate it again, not to mention the potential long term damage to the bathroom.

So what do WE recommend?
– minimum of 8 air changes per hour (more is better since the extra CFM typically comes at very little cost; nothing wrong with 10 or 12 air changes per hour)
– 100 CFM minimum per bathroom, no matter how small it is
– multiple grilles in larger bathrooms to pickup the moisture/smells close to the source
– keep the system quiet (inline fans!!) so that you will use it
– install a timer and leave the fan running for at least 20 minutes after leaving the bathroom

And remember, the standards are there for the builders and not necessarily for you.  Keep the moisture off your walls with adequate CFM and you will avoid mold issues.
