We hope you're reinvigorated and getting started on planning your year, or if you're really good, you’ve already started on projects! The beginning of the year is also a perfect time to evaluate your ventilation needs. You may already have a list of what must be replaced, added, or upgraded, and are already deciding project timelines and goals. This is good! If not, you may need a bit of help figuring out the right amount of fresh air to get moving through your facility so you know what products to get. This is where we can help. It’s vital to your employees’ safety, comfort, and productivity to get the bad air out and the fresh air in.    
 
So, how do you accurately calculate your ventilation needs? It starts by determining the rate at which you need to completely replenish the volume of air in a given room. This is known as an air turnover (or air change) rate and is usually expressed as number of air changes per hour (although it can sometimes be seen as “minutes per air change”). The number of air changes needed ultimately depends on the type of facility or the work being done in a particular area.  For example, a typical warehouse should change air approximately 12 times an hour, though this can vary between 6 and 30.  By contrast, a garage needs to replenish its air 20 times in an hour to protect employees against heat buildup and noxious fumes.
 
Once the air change rate is determined, we can proceed with our calculation. For purposes of this article, we’ll make the math easy (because… hey… who doesn’t love easy math?!). Let’s say you have a 100’ x 100’ building with a 25’ ceiling height.  Based on the work being done, we’ve decided on 12 air changes every hour. Your calculation would look like this:
 
100’ x 100’ x 25’     =      250,000 ft³ 
                                              60/12         =    50,000 CFM
 
Based on our calculation above, you would need to move 50,000 cubic feet of air per minute (CFM) through your facility in order to achieve 12 complete air changes an hour.
 
Being responsible for ventilation in your facility doesn’t have to be difficult. So now that you know your ventilation needs, what’s next? Why not call Patterson?!

​Well, guess what?  It’s summer again.  And – lo and behold – it’s scorching hot out there.  While the extreme heat may send you running for the nearest swimming pool, it can also cause reduced productivity and dangerous medical complications in the workplace.  Let’s dive a bit deeper. (See what I did there?)

Could your facility answer ‘yes’ to any or all of the following?

• Does employee productivity decrease during the summer months when temperatures are elevated?
• Do employees complain about the lack of airflow in the workplace?
• Do processes or equipment produce heat that could be dissipated by air circulators?
• Do certain manufacturing or assembly processes create a large amount of condensation?
• Are there products or components that should be cooled after manufacturing?

So what can be done to neutralize this formidable opponent?  How about the all-important one-two punch of air movement?

ONE: VENTILATE
Moving air through supply and exhaust ventilation not only cools the workplace environment and makes it more comfortable, it also helps control airborne contaminants. Industrial ventilation can also help prevent the buildup of noxious fumes, fire, and odors. Exhausting the hot air from your facility will go a long way toward keeping the temperature, humidity, and air quality at a safe level.


TWO: CIRCULATE
Without movement, air can stratify and stagnate, creating pockets and layers of hot, humid air. In addition, heat leaves our body more quickly when a breeze is present. Fans create airflow that quickly evaporates perspiration from our skin, carrying away heat. The airflow also reduces the thickness of the hot, humid layer of insulating air that builds up around our bodies, thus improving heat dissipation. In short, fans make our natural cooling mechanisms more efficient. Use high-volume, low-speed ceiling fans and portable fans to improve air circulation and natural cooling.


So there you have it!  The one-two punch to knockout heat stress and keep your employees safe, happy, and productive this summer.  And, as always, trust Patterson to be there with the right product for every air movement application.  From ventilation to circulation, Patterson’s got you covered!

Check the calendar.  Guess what?  It’s June.  What does that mean?  It’s going to get hot very soon (if it hasn’t already).  What else does it mean?  You’re going to want fans for your facility – lots of them – quickly.  Not only do you need them fast, you need them mounted and installed fast, too.  Well, we here at Strait Talk (and, yes, Patterson too) also have these goals, and we want to help you avoid any “hiccups” in the process.  So, whether it’s placing an order or tightening the last bolt, here are some tips to “breeze” through your Patterson experience!

• What is your application?  Are you trying to move air down aisles, pick modules, mezzanines, or in trailers?  Then take a look at Patterson’s line of high velocity fans or the new db.  Open areas?  Think about the High-5 HVLS ceiling fan.  Small area cooling?  Patterson’s Fabric Air Ducts, Drum Fans, Cage Fans, and Evaporative Spot Coolers will do the job.

• Know your electrical source.  Is it single phase or three phase power?  277 Volt?  Ordering the right motor type will save time, money, and the hassle of returns/reshipments.
• Will your desired fan fit in the designated area?  If you’re not sure, take some measurements and give your Patterson sales rep a call to discuss.  That’s what they’re here for!
• So your fans have arrived….great!  Now what?  Well, as a wise man (my father) once said, “When all else fails, read the instructions.”  Take a few minutes to familiarize yourself with any installation instructions that came with your fan or fan mount.  If you ordered a High-5, pay special attention to the section on wiring the fan’s variable frequency drive (VFD).  Doing this may help answer some questions, and/or prevent any confusion for you (or your installer) during the setup process. 
• IMPORTANT!  All Patterson fans, regardless of type, come with a wiring schematic (usually printed on the nameplate of the motor).  Be sure to wire your fans exactly as shown.  In the case of a dual voltage motor, take care to select the correct wiring configuration based on your voltage level (usually 208-230 V or 460 V 3-phase service).  Have electrical questions?  Call before you connect – improper wiring can damage motors/VFDs and affect warranty coverage!
• ALSO IMPORTANT!  ALWAYS install all safe guards that come with your fan and/or mount.  They are designed to protect you, your personnel, and your facility in the unlikely event of a failure. 

So there you have it – some simple tips to make your fan buying experience smooth as silk from start to finish.  And as always, Patterson sales reps are standing by ready to dispense timely fan advice and provide free quotes for all your fan needs.

Until next time, let’s keep ‘em cool out there!

We all love to have our cake and eat it, too.  But, as anyone in a successful marriage will tell you, life is about compromise.  (Seriously ladies, you can’t have it YOUR way EVERY time!)  In the air movement business, a trade-off exists when evaluating a fan’s performance versus the noise level it produces.  So how much noise is too much?  When is it ok to use a quieter, lower performance fan?  How do you strike the perfect balance between necessary air flow and acceptable sound levels?  Answers forthcoming!
 
Before we go much further, let’s talk about the different fan types.  High velocity (HV) fans are generally considered high performance – designed to accelerate (or “throw”) air over a distance.  For HV fans, airspeed (measured in feet per minute, or FPM) is more important than volume.  However, this also translates into slightly higher noise levels, typically measured in decibels (dBA).  The other end of the performance spectrum includes cage fans and ventilation fans (think supply, exhaust, shop floor, etc.).  These fans covet volume over speed, and are usually rated in cubic feet per minute (CFM).  Are they quieter than HV fans?  Absolutely… but you won’t feel their airflow once you move more than a few feet away.
 
So which fans are right for your facility, and how should they be used?  Well… both… and it depends!  (How’s that for an answer?!)  For an effective overall air movement solution, it is best to incorporate both fan types.  For example, use large supply and exhaust fans for cross ventilation, and couple them with HV fans to accelerate air movement from one end of the building to the other.  This works particularly well if your aisle ways run parallel to the airflow.  If noise abatement is an issue (industry standard tends to put an upper limit around 80 dBA), mount HV fans well above the floor on columns or racks.  If small area “spot cooling” is needed, employ one or more shop floor or cage fans – allowing for airflow without violating any noise level requirements. 
 
So… maybe that example doesn’t fit the layout of your facility.  Perhaps you’re looking for both performance and low noise?  Great!  Give Patterson a call and learn more about their new db fan!  It offers the performance of an HV fan, with a 70% reduction in noise level!  No matter the fan type, Patterson has the products and the expertise to keep your facility cooler, safer, and more productive!
