  • Product Overview

    Restore water-damaged areas fast with the Ebac Neptune Dehumidifier (10199GR-US). This rugged commercial dehumidifier is ideal for drying water-damaged spots in a variety of commercial, industrial, and residential areas. It features a high-efficiency rotary compressor for maximum water extraction at the lowest possible running costs. It's also equipped with Ebac's "Hot Gas" reverse cycle defrost system to ensure continued operated in low ambient temperatures. Other key features include a continuous gravity drain system, an extra-long power cord, and rugged steel housing.

    Maximum Extraction At High Energy Efficiency

    The Ebac Neptune extracts 52 pints of moisture per day in AHAM conditions (80 degrees F, 60% relative humidity). Its super high-efficiency rotary compressor allows it to run longer and extract more condensation from the surrounding area while keeping your energy costs low. The internal fan moves air quickly through the intake grill and directly to the condenser coils on the inside. Air is processed and dehumidified at 282 cubic feet per minute (CFM). You'll get maximum airflow and maximum moisture reduction at high energy savings.

    Automatic Defrost System for Low Temperature Operation

    A temperature-sensitive, microprocessor-controlled defrost system gives the Ebac Neptune the ability to work in much lower ambient temperatures, as low as 33 degrees F. The unit self-monitors its coils for frost as ambient temperatures in the treatment space change. If frost is detection, the system quickly melts the frost and minimizes operational downtime. This helps you complete each job faster and more reliably.

    Additional Features

    • Gravity Drain - The system comes with a 4.9-foot (0.375 I.D.) PVC drain tube to use for continuous gravity draining
    • Rugged Portable Design - This unit is constructed with a welded and galvanized steel chassis that is epoxy powder-coated and made to stand up in extreme environments.
    • Heavy-duty Collapsible Carrying Handle - The heavy-duty collapsible carrying handle helps you easily move the unit and collapses to save space during transport and storage.
    • 25-Foot Power Cord - The extra-long 25-foot power cord gives you ample distance from a power outlet to place the unit almost anywhere inside the room.
    • Simple Installation - Simply plug the unit into a standard 110-120-volt power outlet.
    • Anti-Vibration Rubber Feet - Help improve stability anywhere you use the unit.


    The Ebac Neptune quickly and efficiently restores water-damaged areas to healthier conditions. This heavy duty commercial dehumidifier extracts 52 pints of moisture per day in AHAM conditions.

    What Customers Love

    • Automatic Defrost - An automated defrosting system quickly melts away ice buildup in temperature below 33 degrees F.
    • Rugged Construction - The unit's rugged steel construction stands up to years of use in harsh environments.

    Things To Consider

    • Add an External Condensate Pump - Consider adding an external condensate pump to drain condensate upward or across longer distances.

    Comments about Ebac Neptune Dehumidifier:

    Use this in a wet basement of 256 sq. ft. with 7 ft. ceilings. It is controlled by a 10 amp. switching dehumidistat, gravity drains into a basement sump and works well for this use. It doesn't move a lot of air, hence better suited for smaller spaces. This is good stout British manufacture with a somewhat noisy metal case. No frills, bells or whistles, looks like a workhorse. Time will tell.

    Seriously Underperforms

    By David Carney

    from USA

    Verified Buyer

    Comments about Ebac Neptune Dehumidifier:

    The Ebac Neptune looks great from a build perspective. Heavy duty top notch parts, attention to detail during assembly. Aside from the rubber feet which fall off easily, (in fact 2 of the feet were just laying their in the bottom of the box when it arrived, a third fell off the next day) you just have every reason to expect it will perform well. But, that's where the good stuff ends. It's all show and no go.

    It's rated 51 pints at 80 degrees, 60% humidity. Now, I know from past purchases of dehumidifiers not to expect but about 50% of the rated value. The manufacturers play fast and loose with their ratings. I would have been satisfied getting 25 pints in a day. At 75 degrees 60% this unit should, according to its rating, put out at least 40 pints in a day. However, in my tests, at 75 degrees, 60% I got no more than 8 pints in a day (20% of what it should do).

    I carefully measured temperature, relative humidity (wet bulb/dry bulb/pressure and also with a hygrometer), and output. I'm not sure how they came up with 51 pints, but it probably should have been rated at 15 to 17 pints (which is still being generous compared to what it actually does). If you have a room that's closed up, and is no more than 300 square feet, and you don't need to pull the humidity down below 52% or so, then this will probably work for you, albeit at a great cost.

    What I wanted when I ordered this, was a unit that would last a long time and perform at least modestly. It may last (time will tell) but for sure, it does not perform.

    Comments about Ebac Neptune Dehumidifier:

    I purchased a Neptune Ebac dehumidifier some years back. It worked non-stop for over 5 years in my wet 2,000 SF south Florida garage. I just bought another one and hope to get 5 more years. It works in cold weather and it works with the doors opening all the time keeping a fairly steady state of 50 percent RH.


    Compact, Quiet and Easy to Move

    By Paul Huffman

    from USA

    Verified Buyer

    Comments about Ebac Neptune Dehumidifier:

    I needed a replacement unit for my basement and the Neptune was the most suitable unit. It is attractive, quiet and easy to move around. It was the best deal, considering cost, capacity and efficiency. The only down side is that it has no built-in humidistat. I am using a Honeywell wall-mounted dehumidistat for control. I bought the Neptune at the end of summer, so it hasn't experienced the most demanding environment yet. But during winter testing, it was able to pull the humidity down from about 50% to 30% in 24 hours.
