UE310AZ20Z Coarse Filter: Why It Is Best for Catching “Soft” Dirt in EHC Oil

The UE310AZ20Z cellulose coarse filter is the main part inside the vacuum oil purifier for fire-resistant oil (EHC) systems. When EHC oil runs for a long time at high heat, it mixes with water and metal bits. This creates “soft” dirt like gums and oxides. This stuff is sticky and changes shape easily. If you don’t catch it, this sticky dirt will clog up the rest of your oil purifier, wear down your machine, and mess up the whole EHC system. Many workers want to know if the fiber layout of the UE310AZ20Z coarse filter is strong enough to stop these soft bits. Actually, the way the cellulose is made and the way the holes are spaced is exactly what you need to solve this sticky dirt problem.

1. Fiber Layout: Stopping the “Squeeze-Through” Problem

The UE310AZ20Z coarse filter uses a special kind of cellulose material. The fibers are not just lined up in a simple way; they are tangled together into a messy, 3D “nest” or mesh. This is much better than basic filters that have loose fibers. This tangled design is made specifically to grab onto gums and oxides.

Cellulose has a natural way of “sticking” to things. When it touches sticky gums, it uses molecular force to grab the surface of the dirt. This stops the soft bits from changing shape and squeezing through the filter. Also, because the fibers are so tangled, they create many layers of walls. Even if a soft bit gets past the first layer, the deeper layers will stop it.

We make sure the fiber thickness is just right. If the fibers are too thin, the oil won’t flow and the purifier will slow down. If they are too thick, the tiny soft dirt will get through. Our original UE310AZ20Z coarse filter is tested in real-plant conditions to make sure the oil flows fast but the dirt stays trapped. Also, these fibers won’t melt or break apart in EHC oil, so the filter itself doesn’t add more dirt to the system.

2. Hole Spacing (Porosity): Balancing Flow and Catching Dirt

The way the holes (pores) are made in the UE310AZ20Z coarse filter is very important for soft dirt. The holes are not too big, so dirt can’t leak through, but they are not too small, so the oil doesn’t get stuck and cause high pressure.

This filter uses a “gradient” design. This means the holes on the outside are a bit larger to catch the big chunks of dirt first. As the oil moves deeper into the filter, the holes get smaller to catch the tiny gums and oxides. This keeps the filter from getting “clogged on the surface” too fast. It makes the UE310AZ20Z coarse filter last much longer while still doing a great job.

A lot of cheap filters get this wrong. Either the holes are too big and let dirt through, or they get plugged up with gum instantly and stop the oil purifier from working. The UE310AZ20Z coarse filter finds the perfect middle ground. Every original part is checked to make sure the holes are the same in every batch, so your EHC oil stays clean every time.

3. Real Results: Working with the Vacuum Purifier

Sticky dirt like gums and oxides are “shape-shifters.” They hide and bend under pressure. Regular coarse filters usually can’t stop them, which means the expensive “fine” filters later in the system have to do all the work and fail early.

The UE310AZ20Z coarse filter has been proven in the field to lock these soft bits in place. Its 3D mesh keeps the gums from moving. Even if your oil gets old and the acid levels go up (which makes more soft dirt), this filter keeps working steady.

As a key part of EHC cleaning, this coarse filter works like a “shield” for the fine filters. By catching the sticky stuff first, it lets the whole system live longer. Many power plants use the UE310AZ20Z coarse filter because it is the best way to keep the oil clean and stop soft dirt from causing a system trip.

4. Daily Maintenance: Keeping it Running Right

The UE310AZ20Z coarse filter only works well if you take care of it. You have to check it often to make sure it’s doing its job.

Always watch the pressure gauges on the oil purifier. If the pressure jump (DP) gets too high, it means the filter is full of dirt and you need to swap it out. If you wait too long, the filter won’t catch the soft bits anymore, the oil flow will stop, and you might even break the pump.

When you swap it, always use a real UE310AZ20Z coarse filter. Fake ones don’t have the right fiber layout or holes, so they won’t stop the gums. Some might even fall apart in the EHC oil and make the problem worse. Our original filters are built for these exact chemicals. When you store your spares, keep them in a dry, clean box. If they get damp, the fibers might swell up and ruin the filter before you even use it.

5. Why Pick the UE310AZ20Z Over Others?

Vacuum purifiers for EHC oil have a tough job. They need to stop more than just sand or metal; they have to deal with the “sticky” stuff. The biggest reason to pick the UE310AZ20Z coarse filter is that it was made just for this.

Compared to a standard paper filter, this one has better “grip,” a stronger 3D mesh, and a smarter hole design. It works perfectly in EHC systems that have a lot of soft dirt. It also resists the chemicals in the oil, so it lasts longer and saves you money on maintenance. It fits exactly with the other parts of your EHC system to create a full wall of protection for your turbine.

Conclusion: Catching Sticky Dirt to Keep the System Safe

The fibers and hole design of the UE310AZ20Z coarse filter are made to trap gums and oxides perfectly. It is the best match for EHC vacuum oil purifiers. Its tangled layout and gradient holes give you the best mix of clean oil and high flow. If you use the right parts and check them often, your EHC oil will stay clean for a long time.
