Charles Austen ET100 Air Pump - 100 L/min - 0.10 bar

The primary advantage is its ability to provide a high volume of quiet, oil-free air, making it suitable for sensitive applications like hydroponics and aquariums, as well as demanding uses like ponds and sewage treatment.

While capable of aeration, its 100 L/min output might be excessive for very small aquariums, potentially causing too much surface agitation. It is better suited for larger tanks, ponds, or specialized systems.

A refurbished unit has been previously used, inspected, repaired if necessary, and restored to full working condition. It may show minor cosmetic signs of use but is guaranteed to function as intended.

Filter cleaning frequency depends on the operating environment. In dusty or dirty conditions, check weekly. For cleaner environments, monthly checks are usually sufficient. Replace filters if they are damaged or cannot be cleaned effectively.

Yes, the Charles Austen ET100 is designed for continuous operation and is built for reliability in demanding applications.

Information regarding the specific warranty for refurbished units is not provided in the product data. Please refer to the retailer's listing for warranty details.

The pump provides 0.10 bar of pressure. This translates to roughly 1 meter of water depth. It's suitable for typical pond and aquarium depths but may be insufficient for very deep applications.

Check that the pump is plugged in and switched on. Verify that the airline tubing is securely connected and not kinked or blocked. Ensure the air outlet port is clear.

Ensure the pump is on a stable surface and not vibrating excessively. Check for any foreign objects obstructing the air intake or outlet. Clean or replace air filters if they are clogged.

Clean or replace the air filters. Inspect the airline tubing and air stone/diffuser for blockages. Ensure the pump's internal diaphragm is functioning correctly (contact support if suspected damage).

Verify the power connection and try a different electrical outlet. Check the fuse in the plug if applicable. If the issue persists, contact customer support.
