The Hailea V series air pumps are ideal for small, medium and large ponds and aquariums; they allow several air stones to be run from one pump so that a large amount of water can be aerated at one time. The filter cover on each pump can be removed so that clean air can be drawn from outside the grow room or tank house, making them ideal pumps for both aquatic and hydroponics applications.
The sizes are

• Hailea V10
• Hailea V20
• Hailea V30
• Hailea V60
