    The model 300A pump is our largest capacity high pressure misting pump featuring:
    • 3 year pump warranty
    • Three self-priming pistons
    • Interval mode misting control with both mist and pause cycles in 1sec increments
    • 0.8 Gallons Per Minute (GPM) capacity
    • Integrated water supply sensor, pressure adjustment valve and pressure gauge
    • Anti-drip HP solenoid valve
    • Motor overheat protection
    • GFCI safety power cord
    Its ceramic-coated stainless steel pistons and aircraft anodized aluminum body make it the most long-lasting misting machine on the market with minimal maintenance requirements.
    Controlled wirelessly via mobile iOS and Android app. If your water has scale causing minerals such as calcium, magnesium, and iron (defined as "hard water"), or fine sediment, consider upgrading to water filter + scale inhibitor to prevent premature pump failure, and clogged and dripping nozzles caused by scale buildup. Damage from scale and fine sediment is not covered under the warranty.

  • Installation requirements

    • Misting pump must be installed at or above grade level, and away from direct sunlight and rain exposure. It must not be submerged in water for any period of time.
    • Water inlet  can be fed with water from the city water line (requires 3/4 garden hose male connection) or gravity fed with water from a bucket. Potable water only. Included polyether tubing should be used to connect pump to the faucet directly as garden hoses often react with chlorine in water and cause chlorine smell in misted air. Integrated water switch will shut off pump when there is no water present. 
    • Power: Outdoor rated 120V NEMA 5-15R GFCI power outlet is required.
    • Pump oil must be added before powering ON for the first time.
  • Maintenance

    • Requires simple oil change every 300-500 hours, or once a year.
    • May require water, o-ring, and oil seal change after 1500-2000hrs (2000hrs translates to 7 years of moderate use or 3 years of very heavy use)
    • Filter change (if optional 0.5 micron filter is used) based on filter specifications. Filter cleaning if standard (included) filter is used is recommended at least once a season.
