Pawfly Pond Air Pump 500 GPH for Fish Koi Ponds up to 3000 Gallons

The PA4000 air pump is a reliable and high-performance option for large aquariums or ponds. It boasts a strong output, with a maximum air flow rate of up to 500 gallons per hour and a high pressure of 0.032 MPa, powered by a 30W motor. This makes it ideal for maintaining healthy underwater environments in fish ponds or water gardens up to 3000 gallons in size.

The pump effectively pushes air into bubblers, quickly diffusing oxygen throughout the pond and promoting water surface movement to prevent freezing in the winter. This helps to keep your fish and plants thriving all year round.

For added convenience, the PA4000 features a rotatable knob on the front that allows you to manually adjust the air volume to meet your desired air flow requirements, ensuring a healthy pond environment.

Safety is also a priority, with the pump automatically shutting off when it operates at an abnormally high temperature, preventing excessive water temperature and protecting the underwater life.

The reliable construction of the PA4000 includes 2-layer thick shells to shield motor noise, and shockproof rubber feet to minimize vibration. This results in a quiet operation, with a sound level below 45 dB.
