Crank Up The Heat (and Static)

The outside temperature is beginning to drop which means the thermostat in my house is getting a workout. I don’t mind the colder temps but my wife on the other hand likes it pretty toasty during the winter months. I am usually downstairs in the living room, so I don’t feel the full effect of the increased heat but our house isn’t as fortunate. The majority of our house has hardwood floors so as the inside temperatures rise and the furnace brings in more of that dry outside air to heat up, it also dries out the hardwood which begins to separate and make a nice creaking sound. We started using humidifiers upstairs and on the main floor to replace some of the moisture lost due to the increased makeup air from the outside.

Another concern with dry air is it creates static electricity.  There are a ton of natural insulators in your house, like carpet or shoes with rubber soles just to name a few, that make it all too easy to build up a static charge and deliver a nice shock. Case in point, over the weekend I was downstairs working and asked our oldest son if he could help me out and get his baby brother out of the pack-n-play. Of course, without hesitation, (heavy sarcasm) he shuffled across the carpet and reached down for his brother, then ZAP! I actually heard the shock before the screams started! I quickly made the realization that I will soon be adding a third humidifier for downstairs as well!

Static electricity is a common nuisance in industrial settings also. It can lead to damaged product, shorting of electrical components, printing or labeling errors, spark generation or cause harmful shock to an operator. EXAIR offers a wide variety of Static Eliminators that are capable of neutralizing the surface static of a material or object to ensure proper operation in many manufacturing processes. For example, our Super Ion Air Knife is a great choice for printing/labeling applications or cleaning a web. With applications requiring more of a focused airflow, we offer our Ion Air Cannon or Ion Air Jet. The Ion Air Gun is the perfect choice for a manual, surface treatment. We also offer our Ionizing Bars and Ionizing Point for close proximity static elimination, where compressed air isn’t available.

An easy way to pinpoint the location and level of static is by using our Model # 7905 Digital Static Meter. The Digital Static Meter is a handheld, portable device that is capable of reading static within 1″ of the surface, up to  +/- 20 kV with 5% accuracy. Once the static has been located, we can then make the best recommendation for a Static Eliminator that will meet the application requirements.
