When you're shopping for compressors, blowers, and air treatment equipment, the first decision is whether you need a dryer, a compressor, or both. The LRSD 85CFM refrigerated air dryer is built for shops that already have a suitable compressor and just need moisture control. The Atlas Copco Z1-22 package combines a rotary compressor with dryers in one unit, so it answers a different question. The price spread is hard to ignore: $980 for the LRSD versus $2,900 for the Atlas Copco package. That gap makes sense once you realize one is a treatment component and the other is a complete air supply.
Quick verdict
Choose the LRSD if you already have a compressor in its intended power range and want clean, dry air without replacing your existing setup. Choose the Atlas Copco if you're starting fresh or need a complete rotary compressor package with integrated drying. If the compressor already runs in your building, a dedicated dryer is usually the shorter path; if you're planning the air system from scratch, the all-in-one compressor package is the more direct route.
At a glance
| Product | Price | What you get | Condition | Key specs |
|---|---|---|---|---|
| LRSD 85CFM Refrigerated Air Dryer | USD 980.00 | Refrigerated dryer only | New | 85 CFM airflow, 110V 60Hz, max 145 psi, for 15HP & 20HP compressors |

Where each product wins
The LRSD wins when your bottleneck is moisture, not air volume. It is the add-on treatment unit, and it gives an existing compressor a dedicated drying stage. The Atlas Copco wins when you need air supply and drying from one piece of equipment. The Z1-22 pairs a rotary compressor with dryers, so you are not matching separate components.
Product notes
LRSD 85CFM Refrigerated Air Dryer

The LRSD is a non-cycling refrigerated dryer rated for 85 CFM. It runs on 110V 60Hz, operates in the 102-145 PSI range, and uses R134a refrigerant with air cooling. The reason to pick it is simple: it adds moisture removal to an air system you already own, and it comes as a new unit with a one-year warranty. A non-cycling design keeps the drying process steady for typical shop applications, which matters when your tools or processes are sensitive to water in the air. The tradeoff is that it is not a compressor. If you don't have a compatible compressor to feed it, the LRSD can't create the air flow it needs to dry, and you will still need a separate air source before this dryer can do its job.
Atlas Copco 30hp Rotary Air Compressors with Dryers

The Atlas Copco Z1-22 is a 30hp rotary compressor package with dryers, oriented horizontally and designed to stay stationary in a medium-duty industrial setting. It runs on electric power, and the advantage is that you get compression and drying in a single package, so system-level setup is simpler. What holds it back is the used condition. You are buying pre-owned industrial equipment, and the Z1-22 model designation confirms which package you are looking at rather than promising a new machine. If your facility is comfortable with used compressors and has a maintenance routine in place, the all-in-one setup is convenient. If new equipment is a requirement, this package will not satisfy that condition.
Final choice by use case
If your compressor is already running and moisture is causing trouble in your lines or tools, go with the LRSD 85CFM Refrigerated Air Dryer. It is the dedicated treatment step that fits into an existing air setup. If you are building a new air station or need rotary air plus drying from one unit, the Atlas Copco Z1-22 package puts it all together.
