Ideal for large spaces, more water capacity for dry climates.

Model 300A pump is our highest 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

The 300A pump’s 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 a 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

Proper installation is crucial for optimal performance and longevity of your misting kit. Please follow these key guidelines to ensure safe and efficient operation:

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 the pump to the faucet directly as garden hoses often react with chlorine in water and cause a chlorine smell in misted air. The integrated water switch will shut off the 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.

Regular maintenance is essential to ensure reliable operation and extend the lifespan of your misting kit. Follow these maintenance guidelines to keep the system in optimal condition:

Requires simple oil change every 300-500 hours, or once a year.
Requires winterization for areas where temperatures drop below freezing. Water must be drained from all tubing and filters, pump and ceramic nozzles removed and stored at above freezing temperatures.
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.
