When you're sorting through compressors, blowers, and air treatment components, choosing a compressed air dryer comes down to a classic trade-off: save money on a used unit or invest more in a new model with detailed specs. In this head-to-head, the contenders are the Ingersoll-Rand Deltech HG10 Compressed Air Dryer Phase at $400 and the Schulz ADS 20 Compressed Air Dryer at $1,381.80. The listed price gap is $981.80, and the two dryers are in very different situations: one is used, and one is new.
Quick Verdict
If keeping the upfront cost low is your priority, the Ingersoll-Rand Deltech HG10 is the lower-priced pick. If you prefer a new dryer with clear performance specs, the Schulz ADS 20 is the better match. The decision really hinges on how much you value new condition over a lower purchase price.

Where Each Product Wins
The Ingersoll-Rand Deltech HG10 wins on upfront cost. It is a used unit with visible wear, so it suits a buyer who wants to spend less and is willing to accept cosmetic flaws.
The Schulz ADS 20 wins on new-condition features and specified performance. It includes an electronic controller, a digital temperature and dew point display, a timer-controlled automatic drain, a temperature probe for the condenser fan, and a quick-disconnect automatic drain valve. It also provides clear airflow and pressure numbers, which helps when you're matching a dryer to a compressor.
Product Notes
Ingersoll-Rand Deltech HG10 Compressed Air Dryer Phase
The HG10 is the used option at the lower end of the price range. Its main appeal is the low upfront cost, and it is said to have been tested and to work. The visible condition includes scratches, scuffs, and marks, so the photos matter. Only the pictured items are included, which means you should not expect extra accessories or manuals. This makes it a reasonable fit for a shopper who wants to keep expenses down and is comfortable with used-condition cosmetics. The trade-off is the typical uncertainty of a pre-owned unit compared with buying new.
Schulz ADS 20 Refrigerated Compressed Air Dryer - 20 CFM, 115V
The ADS 20 is the new, spec-rich side of this comparison. It is a refrigerated air dryer rated for 20 CFM at 100 PSI, with a 220 PSI maximum input pressure and support for compressors up to 5 HP. An electronic controller shows temperature and dew point on a digital display, and it manages the automatic drain valve on a timer while using a temperature probe to regulate the condenser fan. A quick-disconnect automatic drain valve adds convenience. The main limitation is the higher listed price, and the product includes a California Proposition 65 warning about lead exposure, recommending hand washing after handling. If you want new equipment with specified performance and modern controls, this is the one to pick.
Final Choice by Use Case
Choose the Ingersoll-Rand Deltech HG10 if you want the lowest listed price and can accept a used air dryer. Choose the Schulz ADS 20 if you want a new dryer with specified performance and are willing to pay more upfront.
