The General Hydroponics Dual Diaphragm Air Pump is the strongest air pump we sell, capable of delivering a powerful stream of air to four separate locations using the included fully adjustable 4 way gang valve. This air pump is heavy duty with quality construction throughout. Most parts, including the gang valve, are constructed of metal, not plastic like most other brands. The pump also utilizes rubber vibration dampening bushings for smooth, quiet operation. An air pump used in conjunction with an air stone is an excellent way to add oxygen to the nutrient solution in your hydroponic growing system. This will result in a healthy root system and increased growth rates. Dont forget to purchase some flexible airline tubing.
