Patterson Fan Recommends a Combination of Fan Types to Reach Necessary Air Changes Per Hour

Jan. 12, 2010 - PRLog -- For over 20 years, Patterson Fan has helped thousands of companies create properly ventilated working environments. Getting the maximum use of ventilation fans is essential to employee health and productivity. With the onset of green technology, the importance of maintaining and installing the correct types of fans has never been more self evident. By bringing in cooler fresh air, removing noxious vapors (fumes) and adding air flow for natural employee evaporative cooling, utilizing the proper fans works for the health of not only the employees but also of  the environment. Installing quality fans lessons the carbon foot print by using less energy to cool and refresh the air supply.

The rate of ventilation required is measured by air changes—the number of times per minute (ACM) or per hour (ACH) the entire volume of air in an area is completely changed. Rates are dependent on the type of facility and the type of physical activity required to do the job. For example:

Business---Recommended Air Changes

Bakery--- 20 to 30
Restaurant---10 to 12
Commercial Kitchen---30+
Dairy---8 to 10
Manufacturing Shop---10+
Engine Room---30
Workshop---10
Foundry---12 to 15
Fume Generating Process---40 to 50
Garage---10
Spray Booth---50
Warehouse---6 to 8+

Patterson Fan representatives are well aware of all the factors, aside from the length, width and height of the area, that come into play when selecting the optimal ventilation equipment. There are suggested variables to take into consideration as well: number of employees in the area, the amount of product stored in the area, number of machines in the area, whether or not the machines are heat producing, the number of doors and windows, the type of equipment used in the area, if mezzanines are in the area and other factors.

Also needed to be taken into consideration is the age of the current exhaust and supply fans and their maintenance record. Overtime fan motors become dirty, blades collect dust and fan performance is greatly diminished. Generally, all you have to do is look at the facility’s supply and exhaust fans to see their current condition. Dirt accumulation on fan blades is easy to recognize.

For optimum air changes, in addition to the current ventilation fans, it is often necessary to re-evaluate the performance and enhance the current air flow pattern. High velocity fans and/or large industrial ceiling fans are essential components of a good ventilaiton system. These types of fans move air from the ventilation supply fans to the exhaust fans insuring the necessary recommended air changes.

• Wall Exhausters - belt drive or direct drive - both medium and heavy duty, with/without housing, both styles are available for Quick Ship
