Hi, I’m Todd from BlastOne here in Columbus. Today, we want to go through the certain types of dryers that we sell and rent out and give you a quick rundown of their use case and how to actually use them once you get on-site.
When your dryer first gets to the site, you’ll notice that it has various inlet connection points. Down here, we have a two-inch spud and a two-inch close foot, giving you the functionality to use whatever you already have on site. We also offer a three-inch spud connection on the 1600 dryers for full CFM right off the rip.
Before you start, make sure to check which expansion tank says inlet and which says outlet. Always connect the compressor to the inlet side of the dryer to utilize the dryer’s full functionality. If you hook up to the outlet, you’ll bypass many of the drying capabilities because the internals of the pressure tank are set up to direct air from the inlet, through the expansion tank, the deliquescent marbles, and out to the outlet.
Daily maintenance:
– At the bottom of the expansion tanks, burp them to check for excess moisture. On the inlet side, ensure there’s no significant amount of oil coming from the compressor. If you see a lot of oil, check your compressor for leaks to prevent hindering the surface you’re spraying.
– There’s another ball valve on the outlet side; burp it to check for any discharge.
Before and after energizing the system, ensure the hand wheel is not loose. After pressurizing the tank, gently check for movement. Always depressurize the tank before tightening the hand wheel for safety.
This system alleviates moisture in the pressure tank and is used to dump the system when ready.
In Columbus, we’ve started installing 150 psi pressure relief valves on our dryers as a safety feature. If this valve pops off frequently, check and ensure your compressor is set to the appropriate pressure, usually 120 psi for most of our equipment.
We also provide an after-cooler fan to drop the temperature of the air from the compressor, allowing maximum moisture removal in the expansion tank and preventing extra moisture or abrasive clumping at the nozzle.
Daily checks include:
– Ensuring the oil reservoir for the fan is filled with non-freezing air tool oil.
– Visually inspecting for leaks and ensuring everything is lubricated to prevent the fan from getting stuck.
To adjust the fan’s pressure, use the regulator knob to set it between 80 and 100 psi, affecting the fan speed. Adjust the oil dial for one drop every 15 seconds to ensure proper lubrication.
On the expansion tank outlet, we have another three-inch spud and multiple connection options like crow’s feet and two-inch spuds for field connections. We also provide two Chicago lines for air tools or other site needs.
This is a basic overview of hooking up our dryers on-site. If you have any more questions, you can click the link below or contact your salesman for answers.
