The General Hydroponics® Dual Diaphragm air pump is extremely quiet and the only air pump in the world manufactured exclusively for hydroponics systems. This high output pump has four (4) adjustable 1/4″ outputs that can be teed off to power up to twelve air driven hydroponics growing systems such as the WaterFarm. In addition, growers who use our Dual Diaphragm air pump can use it to reliably oxygenate their reservoir with air stones. 3 psi, 320 gph (20 L/min).

The Rebuild Kit for the Dual Diaphragm Air Pump gives customers the option of fixing the pump rather than replacing the entire unit. Kit includes two replacement diaphragms and two replacement lock-nuts.

Promoting Good Aeration

Dissolved oxygen in water is important for plant health. One way to achieve this in a nutrient tank is to continuously aerate the mixture. In recent years, the advantages of making adequate and even extra oxygen available to plant roots have been brought into sharper focus through the growing popularity of aeroponic and fogponic technologies.

Good aeration promotes nutrient uptake, sometimes dramatically, and aids in the growth of beneficial organisms. It also discourages the development of pathogens in the form of anaerobic bacteria. Adding one or more air stones or other bubble-producing devices to your nutrient tank is a form of extra insurance against shortfalls.

Another benefit of amping up the oxygen content of your mixture is that aeration keeps the liquid in motion and blended. It also helps maintain a consistent temperature and discourages algae growth.

The cells of the plant will die when the cells in the roots do not have access to oxygen and this can cause the entire plant to die as well.
