Direct Drainage Reviews

The Charles Austen ET100/ET120 Air Filter is suitable for use with the Charles Austen ET100 & ET120 Air Pump.

Your inlet filter should be washed out every 6 months and replaced every year. Failing to do so can reduce the pumps flow up to 30% and cause possible overheating.
