The Hailea ET40 is a linear diaphragm air pump which provides a reliable, clean oil free air source. These pumps use electromagnetic force to move a diaphragm up and down creating a chamber air is pumped from. They are very extremely durable  and reliable as they are often used to oxygenate fish ponds and aquariums.

With a large 40 ltrs per minute capacity these pumps will run multiple air stones in deep water culture systems or aircages as used in the Autopot systems. Use in conjunction with our manifolds found here
