EXAIR’s Gen4 Power Supplies, the Foundation of Gen4 Static Eliminators

In the fall and winter seasons, the air becomes much drier. You may be familiar with the unpleasant shock you get from the door knob after walking across a carpeted surface. While this type of shock doesn’t generally cause any sort of problems, in many industrial processes this static electricity can cause a wide range of issues. These may manifest as nuisance shocks to an operator – similar to the door knob example, but it can also cause problems with the finish quality of coatings and paint. It will make ink jetted codes unreadable, cause blemishes in printing processes, and short out sensors being relied upon for counts and quality inspections…just to name a few. 

The reason that you experience static shocks more frequently during winter is due to the relative humidity. At colder temperatures air does not hold as much water as it does when it’s warm, and since water conducts electricity, higher humidity keeps static at lower levels. Even though you’re heating your house to a similar temperature, the air that is being drawn into your home and heated is still the dry cold air containing less moisture.

So how do we tackle this static problem that’s running rampant in your processes? EXAIR has a wide range of Static Eliminators available to ship same-day from stock. Each of which is designed to handle different types of applications. At the heart of these Static Eliminators is the EXAIR Power Supply. Available with either 2 or 4 ports, the Gen4 Power Supply is suitable for use with either 115V or 230V via the selector switch on the back. A 6’ modular power cord and lighted power switch are included. The modular cable protects sensitive electronics against electromagnetic interference while easing connections and routing. An integrated fuse (spare fuse is also included) on the primary protects against voltage spikes.

Two shielded cables are included with both styles of Power Supply. A standard 3-prong outlet for North American customers, and another that allows you to install your own plug to accommodate any style of electrical outlet. The integrated ground connection on the high voltage side allows for complete connection using just the bayonet connector. A grounding post on the front-face of the Power Supply is available for bonding of the Power Supply to machine frames. Shunting circuitry designed into the Power Supply protects the user against any short circuit on the secondary side.

The Power Supply includes an integrated flange for easy mounting in any orientation. Rugged and durable stainless steel connections are present at the high voltage side vs the plastic connectors of the competition. This facilitates the integrated ground and shockless design of all of our Static Eliminator products. The Power Supply is both RoHS and CE compliant, as well as UR Listed.

Here at EXAIR we’ve helped customers in a wide range of industries solve their static issues within their processes.
