These air pumps are a powerful and reliable option for ponds, tanks and aquaponic beds up to 4 ft deep. **If air stones are more than 4' deep there will be undue wear on the diaphragms and will void the warranty.

Aluminum covers and internal noise absorbing systems make these linear pumps surprisingly quiet and rugged. The pump housings are designed for use outdoors but are not waterproof so they need to be kept up out of puddles and with good ventilation. Pumps have 6 ft power cords, 110 V, and a ⅜" Barb air outlet. CUL certified. Six month warranty.
