  • What is Atmospheric Water Generation?

    Atmospheric water generation is a technology-based process used to condense water from the air, then capture and filter that moisture into drinkable water.

  • How does it work?

    Pacific Airwell products collect water from humidity in the atmosphere. This air is chilled to the “dew point” and the moisture is condensed onto patented, stainless steel or specially coated coils, then channeled through advanced filtering chambers to provide a reliable source of clean drinking water. This technology enables significant amounts of water to be extracted from the air and purified efficiently at a relatively low cost per liter or gallon.

  • Under what environmental conditions is an atmospheric water generator able to produce water?

    Pacific AirWell's technology will produce clean water effectively and economically from the air with humidity as low as 30%. This technology demonstrates cost savings and other notable advantages compared to desalination. Optimal water generation depends on average temperature and relative humidity.  Higher humidity and temperature conditions improve the cost effectiveness of producing clean water.

  • How pure is the water produced?

    The water produced by Pacific AirWell products is 99.9% free of impurities, which means it is free from bacteria, known viruses, air pollution and metal oxide contamination. The advanced filtering process works all day and night, non-stop, maintaining an optimal level of purification. Water is channeled through several types of filters depending on the model, including an activated carbon filter, as well as the innovative HaloPure filter by world-renowned water purification company HaloSource (www.halosource.com).


    Water filtered with Pacific AirWell's technology has low TDS (Total Dissolved Solids, which is the amount of all inorganic and organic substances in the water).

    • Commercial and Community water units can provide scalable solutions for delivery of clean drinking water by linking multiple units to meet volume demands.
    • Employs a high standard of 99.9% purification of water from bacteria, known viruses, air pollution and metal oxides.


    Unit performance and maintenance needs can be monitored remotely by Pacific Airwell (commercial and community models only).


  • What kind of energy is used and how much is required?

    All Pacific AirWell models use electricity with one special model using waste oil as the primary source of energy. Pacific Airwell may develop options for using wind and solar energy in the future.


    The residential Model 2500, for use in the home and office, uses 550 watts of electricity.

    The power source for the Water Pro 400 is three-phase electrical power; the unit can be easily integrated into the existing electrical utility system, using 25kW of energy.

    The Water Pro 100 uses waste oil as its energy source to produce cooling, which is its largest demand for energy, but the unit still requires some electricity to run the pumps and controls. It also has the ability to run on natural gas and propane when oil or diesel is not available.


  • How much water can be produced with Pacific AirWell products?

    Water production can range from up to five gallons/19 liters per day for the household and office models, to more than 400 gallons/1,500 liters per day for the community or commercial models, and even more through modular aggregation of these units. With the introduction of the Pacific AirWell 20K, more than 20,000 gallons/75,000 liters of water per day can be produced with just a single unit.  Water generation efficiency depends on average temperature and relative humidity. When humidity is high, water can be generated and stored for use when humidity is significantly lower. Tables indicating the water production rate at various temperature and humidity conditions are provided in the data sheets for each unit.

  • What models does Pacific AirWell manufacture? How much pure water can each model produce? What are their potential uses and costs?

    Pacific AirWell produces atmospheric water generators for household and office use, as well as commercial and community use.


    The Model 2500 is for use in homes and offices with 4 to 6 people. It can produce up to 5 gallons/19 liters of pure water per day in a high humidity, high temperature environment, and stores 3.5 gallons/13 liters. It uses 550 watts of electricity.

  • What does it take to operate and maintain atmospheric water generators?

    Pacific Airwell products are designed to operate continuously and only require modest periodic maintenance consisting of filter changes and general cleaning.


    Pacific Airwell's commercial and community products have an option of remote monitoring via internet service that allows for predicting scheduled maintenance and monitoring of key operational parameters of the equipment.


    Air filters should be replaced four to six times a year depending on local atmospheric conditions. Water filters should be replaced two to four times per year depending on the model in service. These cartridges take only minutes to replace using an automated system shutdown feature. Typically no compressor maintenance is required.

    For the Pacific AirWell 100, our waste oil burning unit, the cleaning cycle is dependent on the run time and the amount and type of oil burned. The cleaning can be done by almost anyone after they have received basic maintenance training by the distributor or service provider.
