Santa Fe Compact70 vs Advance Dry110 vs Oasis105 vs Classic

Santa Fe’s four current free-standing dehumidifiers are not four versions of the same box. The Compact70 is short and horizontal; Advance Dry110 has dual exhaust outlets; Oasis105 uses a variable-speed blower and a positive-pressure drain; Classic is a tall vertical basement design. All four need a gravity route to a lower drain in their standard configuration, and none has a built-in lift pump or collection bucket.

The comparison uses the manufacturer’s current U.S. category page, its Product Wizard, and the exact product pages, manuals and specification sheets linked in each review. The exact-page raw HTML request was blocked for this check; each current rendered page was inspected and core identity/rating decisions were cross-checked with archived manufacturer manuals and sheets.

First compare the exact rating condition

At 80°F/60% RH, the manufacturer rates the Compact70 at 70 pints per day, Advance Dry110 at 110, Oasis105 part 4044510 at 102, and Classic part 4044710 at 116. At 65°F/60% RH, their sheets list 43.7, 70, 67 and 76 pints respectively. Lower-temperature values are useful for a cooler basement or crawl space, but they are still controlled test points, not a daily yield guarantee. The Oasis name is especially easy to misread: the current detailed product page and 2026 sheet say 102 pints, while the Wizard shows 105. Use the exact model’s sheet if a capacity threshold is essential.

The manufacturer also publishes pints-per-kWh and Energy Factor at two conditions. Those numbers are not the same as EPA Integrated Energy Factor. An exact current ENERGY STAR dataset query did not find these four part numbers/names; I do not mark them certified or insert a guessed IEF. Published square-foot guidance also varies with sealing and source: treat it as a starting point, not a load calculation.

Choose the cabinet and airflow for the real opening

• Compact70: 12 × 12 × 21 inches, 55 pounds, horizontal and short. It suits a genuine low-clearance opening, but not a buyer who needs an integrated pump. Its manual requires a gravity drain trap and a falling hose run.
• Advance Dry110: 14.35 × 24 × 29 inches, 102 pounds and two exhaust outlets. The outlets can distribute air to multiple areas through a planned duct layout; they are not independent humidity zones. The product includes a built-in P-trap design, not a water-lifting pump.
• Oasis105: 24 × 14.5 × 16 inches, 59 pounds. Its variable-speed fan can trade quieter low-speed operation against higher ducted airflow; its positive-pressure gravity drain avoids a conventional external P-trap. The width is a major constraint, so measure the opening and filter access.
• Classic: 20 × 36 × 17 inches, 110 pounds, vertical flow-down. This is the basement-oriented cabinet in the group. Santa Fe’s page lists crawlspaces among possible uses, while the Wizard says the Classic is not applicable to crawlspaces. Keep that conflict open and do not select it on a crawlspace claim alone.

Dimensions exclude the needed air clearances and service access. These are heavy installed appliances, even when the Department of Energy calls a configuration “portable” or stand-alone. Plan the path into the space, level support, electrical access and filter removal—not just the door width.

Water route is a pass-or-fail question

All four have no bucket, no built-in pump and a documented gravity-drain arrangement. The Compact70 manual calls for a trap and a 1-inch drop per 10 feet. Advance Dry110 has an internal P-trap option. Oasis105 uses a positive-pressure drain that does not require an external P-trap. Classic ships with a six-foot attached gravity hose. In every case the standard hose must reach a suitable lower outlet without kinks or blockage. A separate Santa Fe pump kit can be purchased for an uphill discharge, but it is not built into these four and should not satisfy a built-in-pump need.

Do not confuse optional duct kits with central HVAC integration. The manufacturer describes the four as free-standing/portable products and some offer ducting options for divided spaces; their exact pages do not establish the documented whole-house return-to-return plan used by the HVAC-ducted finder question. If a fixed HVAC installation is essential, compare a product family whose exact manual documents that plan, such as the separate Ultra whole-house line, rather than stretching this group’s documentation.

Quick selection

Pick the Compact70 for a 12-inch-high opening, the Advance Dry110 for dual discharge and a higher 110-pint test rating, the Oasis105 for variable-speed airflow and its low-maintenance positive-pressure gravity drain, or the Classic for a suitable vertical basement installation. If the only available drain is higher than the unit, none of the four fits the standard pump-lift answer. If a built-in bucket, smartphone control or confirmed ENERGY STAR listing is essential, the current evidence does not support any of these as the match. Confirm exact part number, filter size, temperature limits, duct layout and installation protection before ordering.
