Moisture in compressed air can cause rust, clogged tools, and compromised finishes. Refrigerated dryers cool the air to condense moisture, making them a common solution for protecting downstream tools and equipment. If you're shopping in the compressors blowers air treatment space, you're probably balancing two needs: how much airflow your compressor produces and how much pressure your system actually runs at. The two dryers here take different paths to the same goal.
Quick verdict: The LRSD refrigerated air dryer is the lower-priced option and is built around airflow, supporting larger compressors. The SCHULZ is the higher-priced option and is built around pressure and convenience. Pick the LRSD if you want more drying capacity for a bigger compressor and a lower upfront cost. Pick the SCHULZ if your system needs to handle higher pressure and you prefer a kit with automated controls. Both are new non-cycling refrigerated dryers, so the real difference comes down to your compressor's demands.
| Product | Listed Price | Airflow | Max Pressure | Compressor HP | Price Bar |
|---|---|---|---|---|---|
| LRSD 85CFM Refrigerated Compressed Air Dryer | USD 980.00 | 85 CFM | 145 psi | 15 HP & 20 HP | |
| SCHULZ 50 CFM Refrigerated Compressed Air Dryer Complete Kit | USD 1,552.28 | 50 CFM @ 100 PSI | 200 PSI max input | 10 HP & 15 HP |
Where each product wins
The LRSD wins on airflow capacity and compressor-size support. It provides more CFM than the SCHULZ, which is meaningful for a larger compressor. That extra capacity gives you more headroom for moisture removal across multiple tools or higher-demand applications. It also costs less, with the listed prices separated by $572.28.
The SCHULZ wins on pressure rating and included controller. Its max input pressure is significantly higher, and the kit includes an electronic controller that manages the drain valve and condenser fan automatically. For a system that runs at higher pressures, the SCHULZ provides more headroom without sacrificing automated operation.
LRSD 85CFM Refrigerated Compressed Air Dryer

The LRSD delivers 85 CFM of drying capacity at up to 145 psi. It runs on 110V/60Hz single-phase power with a 1-inch interface and includes a 1-year warranty. The non-cycling refrigerated design uses R134a refrigerant and air cooling, with an ambient operating range of 0-95°F and an intake air temperature limit of 113°F. Installed power is 550W, and the unit weighs 86 lb with dimensions of 30 x 17 x 32 inches. The trade-off is the 145 psi pressure ceiling, which is lower than the SCHULZ's max input. If your compressor runs at higher pressure, this unit will not be the right match.
SCHULZ 50 CFM Refrigerated Compressed Air Dryer

The SCHULZ ADS 50 is a 50 CFM dryer accepting up to 200 PSI max input. It runs on 115V single-phase and includes an electronic controller that displays operating temperature and dew point while automatically managing the drain valve and condenser fan. This maintains dependable, hands-off operation even in environments with elevated ambient and inlet temperatures. The trade-off is lower airflow capacity than the LRSD, along with a higher listed price. The listing also includes a California Prop 65 warning. For systems that prioritize pressure capability, this kit is the stronger option.
Final choice by use case
If you're running a 15 HP or 20 HP compressor and want maximum moisture removal for the LRSD's $980 listed price, it's the direct pick. If you need a complete kit with automatic controls and a higher pressure ceiling for a 10 HP to 15 HP compressor, the SCHULZ at $1,552.28 is the better match.
