Hot melt applicators are used in high-speed packaging to apply melted hot glue onto the sub-straights of boxes. There are several different styles of applicators that Universal Systems manufactures, both single module and multi-module. If you are running a multi-module pneumatic applicator, you can run the air to the module either independently or at the same time, otherwise known as independent air versus common air.

If you are running your system where your modules all fire at the same time, common air applicators are what you want. They are easy to use and only require one solenoid to fire all the modules on that gun. They are by far the most machined and used applicator gun in the industry.

If you are running your system where your multi-module gun fires the modules at different times, then you will need an independent air applicator. An independent air applicator requires each module to have its own airline and solenoid to fire independently of the other modules on the manifold. It allows for more versatility, but is more expensive to operate due to the need for multiple solenoids.

If you are running a multiple module applicator and don’t know if you need a common air or independent air operation, call your sales rep at Universal Systems. We will help you identify the positives and negatives of each set up and understand which is the best for your line. An added value of using a Universal Systems ProBilt applicator gun, is that our manifolds are machined with our unique design to allow you the versatility to go from common air to independent air with just the addition of one of our patented plates. This way, if you decide to change your setup after purchasing a manifold, they can be easily converted between common air and independent air.
