Rotary Screw Air Compressors with Dryers
Rotary screw air compressors with dryers combine a continuous-duty rotary screw compressor and an integrated refrigerated air dryer in a single factory-matched package. CompressorPros carries rotary screw dryer systems from 3 to 30 HP in single phase and three phase configurations across six brands. Standard shipping is free.
What Are Rotary Screw Air Compressors with Dryers?
A rotary screw air compressor with a dryer packages a rotary screw compressor and a refrigerated air dryer into one system. The dryer removes moisture from the compressed air before it enters the distribution line, preventing corrosion in piping, water damage to pneumatic tools, and defects in paint, coating, and finishing work. Because the dryer is factory-matched to the compressor's CFM output, there is no risk of pairing an undersized dryer with the compressor. These systems deliver 100% duty cycle and serve auto body shops, manufacturing plants, woodworking studios, and any facility where continuous dry air is essential.
Single Phase vs. Three Phase
Single Phase Rotary Screw with Dryer
Single phase models run on 230V single phase power and are available at 3, 5 and 7.5 HP. They serve smaller shops and facilities without three phase electrical service. Tank sizes are typically 60 gallons, and the complete system (compressor, dryer, and tank) ships as a single unit. The Quincy QGS 5 TMD-1 5 HP Single Phase Rotary Screw with Dryer is the top-selling single phase rotary screw dryer system on the site.
Three Phase Rotary Screw with Dryer
Three phase models run on 208V, 230V, or 460V three phase power and are available from 3 to 30 HP. They draw less amperage per HP, run more efficiently, and scale to higher output than single phase equivalents. Tank sizes range from 60 to 132 gallons. The Quincy QGS 15 TMD-3 15 HP Rotary Screw with Dryer is one of our top selling rotary screw air compressor with dryer. Systems at this HP level and above deliver the CFM needed for multi-bay shops and continuous production environments.
Types of Rotary Screw Compressors with Dryers
5-7.5 HP Rotary Screw with Dryer
The entry tier for rotary screw dryer systems. These units deliver 15-30 CFM and pair with 60 gallon tanks, providing a complete dry-air system in a compact footprint. They are well-suited to single-bay auto shops, woodworking studios, and small commercial operations stepping up from piston compressors.
10-15 HP Rotary Screw with Dryer
The core of this category. These systems deliver 35-55 CFM on 120-132 gallon tanks and serve multi-bay shops, fabrication facilities, and mid-scale manufacturing operations. The ABAC AS-10503TMD-131 10 HP Three Phase Rotary Screw with Dryer is the compressor with the most sales across all rotary screw dryer systems, and the Elgi EN11-125-120T-G2 15 HP Three Phase 120 Gallon Tank Mount with Dryer offers extended maintenance intervals on a 120 gallon receiver.
20-30 HP Rotary Screw with Dryer
The upper range for tank-mounted dryer systems. These deliver 70-130 CFM on 132 gallon tanks and serve larger manufacturing operations, fleet maintenance shops, and applications running multiple air tools or processes simultaneously. Three phase power is required at this tier.
Key Specifications
- CFM (Cubic Feet per Minute): Rotary screw dryer systems deliver roughly 15-130 CFM depending on HP. The integrated dryer is factory-matched to handle the compressor's full CFM output, so there is no need to calculate dryer sizing separately.
- HP (Horsepower): Available from 3 to 30 HP. For higher HP needs, a base-mount rotary screw compressor can be paired with a standalone dryer from the dryers and compressed air treatment category.
- Tank Capacity (Gallons): 60 gallon tanks for 3-7.5 HP systems; 120-132 gallon tanks for 10-30 HP systems. Larger tanks reduce motor cycling and provide a deeper air reserve during peak demand.
- Max PSI (Pounds per Square Inch): Most rotary screw dryer systems deliver 125 PSI. Some models offer a 150 PSI option for applications requiring higher working pressure.
- Dew Point: The integrated refrigerated dryers typically produce a 38-40 degree F pressure dew point, sufficient for spray painting, powder coating, and most shop and manufacturing applications.
- Voltage/Phase: Single phase models require 230V. Three phase models are available in 208V, 230V, and 460V. Verify your electrical service before ordering.

FAQ
Why buy a rotary screw compressor with a built-in dryer? A factory-matched system eliminates the risk of pairing an undersized dryer with your compressor. It also simplifies installation (one unit, one connection), reduces floor space, and often costs less than purchasing a rotary screw compressor and standalone dryer separately.
What is the most common mistake when buying a rotary screw dryer system? Ordering the wrong voltage. Rotary screw dryer systems above 7.5 HP are available in multiple three phase voltages (208V, 230V, 460V), and not all models support all three. Check the nameplate on your electrical panel or have an electrician verify your facility's voltage before placing an order.
What is the difference between a rotary screw dryer system and a piston dryer system? Rotary screw systems deliver 100% duty cycle, lower noise, and higher CFM at equivalent HP. Piston compressors with dryers cost less upfront and deliver higher maximum PSI (175 vs. 125-150). If you run air tools continuously throughout the workday, rotary screw is the better fit. If your demand is intermittent, a piston system offers strong value.
What dew point does the integrated dryer produce? The refrigerated dryers in these systems typically produce a 38-40 degree F pressure dew point. This is sufficient for spray painting, powder coating, woodworking finishing, and most shop and manufacturing applications. For applications requiring dew points below -40 degree F, a separate desiccant dryer is needed.
Can I upgrade from a rotary screw without a dryer to one with a dryer? If you already own a rotary screw compressor and want to add drying capability, a standalone refrigerated dryer can be plumbed inline. However, if you are buying new, an integrated dryer system is typically more cost-effective and space-efficient.
Does CompressorPros offer free shipping on rotary screw dryer systems? Yes. Standard shipping is free, direct from the manufacturer, on every unit in this category.
