On a hot, muggy or humid day, a little bit of air circulation can make a big difference in terms of comfort. Many of us accomplish this through central air conditioning, while either it be at the office or at home. But larger, more unique workplaces such as the gym, bakery or warehouse have a tendency to get hot and stay hot, making central air conditioning inefficient in terms of a cooling source. That’s where oscillating fans come into play. These simple and common types of fans are often run on a single electronic motor, circulating air in the immediate...

Exhaust fans are essential in any bathroom, whether it be in your home bathroom or your factory employee restroom. They serve two primary purposes – removing bad odor from the room and also removing moisture and humidity from the area. While the former role of bathroom exhaust fans is more for convenience and comfort than anything, the later role they serve is more important. That’s because running faucets and showers within a confined space, such as the bathroom, add moisture and humidity to the air. And too much moisture build up can lead to mold and mildew growth, which is...

The Home Ventilation Institute(HVI) recommends that bathrooms up to 100 square feet be ventilated by intermittent or continuous ventilation with an exhaust fan that provides airflow of at least 1 Cubic Foot per Minute (CFM). For an 8×5 bathroom, a 40 CFM unit is recommended (multiply to yield the CFM: 8×5=40). Bathrooms over 100 square feet should be ventilated according to fixtures. A toilet, shower, or tub each require 50 CFM. A jetted tub requires at least 100 CFM. Each fixture is added to the total. If a bathroom has a toilet, jetted tub, and separate shower, the CFM recommendation...

Here are some tips for making the most of bathroom exhaust: Be sure you have a reliable bathroom exhaust system. If your fan is an older model, look into installing an energy-efficient and quiet bathroom exhaust system for air movement and moisture removal. Bathroom fan exhaust points should ideally be located above or near a shower or bath tub and inside an enclosed toilet room. Exhaust fans should be located away from the air supply. Bathroom doors should be undercut to allow supply air to be pulled into the room. Check your ductwork for sharp turns. Maximize airflow by keeping...

It’s important to know some facts about bathroom exhaust ventilation before making a decision on fan installation or replacement. Here are some facts: Bathroom fans help maintain the structural integrity of a house by removing excess humidity that can encourage mold and rot. In bathrooms with windows, it is still important to install an operational exhaust system. The most common bath fan is a propeller or axial fan. A propeller exhaust fan can move large amounts of air without the requirement of tremendous force. Centrifugal fans uses centrifugal force to push air out of a space. They are more expensive...
