Direct Drainage Reviews


The ETD Series range of air pumps ensures that there is plenty of water movement in the waste water applications, this boosts the dissolved oxygen levels in the water, allowing the aerobic bacteria to decompose.  

The ETD series offers a high flow from a small footprint, and are an alternative to expensive and ineffective rotary vane and side channel blowers.
