High Power Super Air Nozzles Provide Forceful Air Flow

When considering the application of a compressed air product, we have an awful lot of discussions with callers about the amount of force generated.  Now, if that’s all you want, you’re not going to get more force from compressed air flow from anything but an open ended blow off.  There are problems inherent with this: it’s unsafe, it’s loud, and it’s a horribly inefficient way to use compressed air.  By the time they’ve called EXAIR, they probably know this, but the main concern is still the same: solving their application.

Good news is, you don’t need a lot of FORCE for most blow off situations.  Think about it…how much do sawdust, machining chips, coolant droplets, etc., weigh, anyway?  All you really need to do is optimize the air flow, which is EXACTLY what EXAIR Intelligent Compressed Air Products are engineered & designed for.  So, we talk a LOT about how often a high amount of force isn’t needed in compressed air blowing applications.

Then…I got a call from a user who needed force.  They had an air knife installed to blow parts out of a mold, as the halves separated.  There’s a rectangular array of parts in a multi-cavity mold, and the air knife just wasn’t getting them all out, all the time.

The air knife, was, of course, originally chosen for its efficiency, but it just wasn’t delivering the needed “punch.” They even tried other shim thicknesses (which increases the outlet air gap) to increase the flow & force delivered, and that helped a little, but wasn’t 100% effective.

The solution came in the form of an array of HP1125-9212 2″ High Power Flat Super Air Nozzles, supplied with 12″ Stay Set Hoses.  They’re able to mount these closer to the mold than the air knife, and the ability for each nozzle to operate independently meant they were able to be aimed precisely where they can do the most good.  They are now able to evacuate the molds the first time, every time.

Sometimes, you DO need the high force of the HP1125 2″ High Power Flat Super Air Nozzle

If you have questions about how to get the most out of your compressed air use, give me a call.
