I'm brian with halo services and hvac school and i'm eric with calo services in hvac school and today we're going to be talking through oil filters. This is for large refrigeration and air conditioning applications. Typically, this is going to be seen most in rack, refrigeration, grocery refrigeration, but we want to show some of the differences between the westermeyer model and another common model. That's used out in the field and just kind of show some of the features and benefits of each today.

So what are some of the first things that stick out to you when you first started uh working on this model, eric? Well, one thing that that was pretty different about this than the spoiling is: the connections aren't in the top flange they're, actually on the body of the housing. So this would be your connection points on the scorland unit, and these are your connection points on the western meyer unit. I guess the biggest difference being that in this model, you're removing the shell and the top is staying stationary and in the western meyer model, the top is being removed and the shell is staying stationary, which is a pretty big difference in how you would actually work With and service it another thing that i noticed right off. The bat is that, on this model, you actually have separate nuts that you have to manage so sort of a two-handed operation in order to get the oil filter in and out versus the westermeyer, where the flange itself is actually threaded.

It's gon na be a lot easier to put together because remember we're pulling the base off of this so you're holding this. Then you have to drop one of these through and get it started. So you're going to have to like use a finger here and then do this number to get to get a couple. Bolts started to be able to put the rest in which is not insurmountable, but it is annoying also on this.

These have the option for either rotor lock, connections, uh or sweat connections. Uh, whereas with this one here, what what type of connections are these? Do? You know it's just regular pipe threads. You would put a threaded adapter there, probably to go to flare, probably the flare area, usually they're flare. I mean you could thread and then sweat, really whatever you wanted to do, but you also have to you know, get those fittings and and whereas, in this case, if you wanted to do sweat, you could sweat the body stay stationary or you could use rotolock for Those of you who aren't familiar with rotolock rotolock actually uses a o-ring in there.

It's generally, i think teflon o-ring is that right, yeah, so generally a teflon o-ring, and so they are a more consistent seal. As you know, flares do tend to be leak points in the field, and so this isn't necessarily dictating that you have to use flare, but that would be the most common type of connection that people would use in that application. Another nice thing with this stand is that you can easily mount these on either a vertical or horizontal application super easily without having to field configure, let's go ahead and show that how hard is that to do you just pull this pin here and take that out And you can rotate it horizontally. The pin back in there goes on, so that's our horizontal application and then all we have to do to put it back vertical.

So now, let's just show the assembly and disassembly of this model versus the other model. So there's a little uh little area for you to easily hook on to on the filter, um for you to pull it out and that's the that's the assembly i mean that's the disassembly. So let's go ahead and reassemble this bolt here is a little bit longer. Now again, in real life, when you're doing this you're going to want to follow the specific torque, specs and you're going to want to follow a pattern, an uneven pattern rather than going off on one side or the other.

But as you can see, this allows for one hand operation, so this shows the key difference here with, in this case the flange or the top is staying in place and then we're removing the entire shell so to demonstrate it properly. We could mount it here and then show us pulling the top off, but that's not how it would work in real life, because you would have your tubing attached here and so instead, we're going to just kind of show it free and we'll disconnect it and show How this comes apart, you'll also notice that in this case we have our port on the bottom side. Where, on this one, we have it on top, you can see, we have a separate nut and bolt. This would be clamped until you're ready.

So that's what most guys do is leave the clamp on, but still reassembly is kind of tricky, so that this clamp would typically be holding the shell and you could remove it last. If you wanted to right, then drop in this case with the spoiling, you can see that the filter has to fit onto this top portion, because this is the part that's staying stationary and then the entire shell is moving off of the filter. Just based on my assessment, there are some kind of key differences um most of them. I would see as advantages with the westermeyer oil filter.

But again, the most important thing is: if you're working on systems that have oil filtration, you need to make sure that you're actively managing the oil system that you're actively changing your oil filters, because, again, lubrication is absolutely huge on these systems. It's it's one of the biggest things that can cause problems if you are allowing the oil to get contaminated now, you're going to have significant compressor problems down the line which can really cascade through the entire system, because in these managed oil systems, you have one oil Supply that's being fed through multiple compressors, so one problem can cause a lot of issues uh having an oil filter. That's easy to maintain and that's installed properly is going to be absolutely huge, i'm brian orr and i'm eric nelly, we'll catch you next time.
