Air Pump for Aquarium 180 L/h

Quick Answer: The Air Pump for Aquarium 180 L/h is a mains-powered aquarium air pump with a rated output of 180 litres of air per hour, pictured as a compact white unit with a green top panel. It feeds air through airline tubing to an air stone or filter, keeping tank water circulating and well supplied with oxygen.

Specifications

Choosing and Placing an Air Pump

Air pump output is usually matched to the volume and depth of the tank and to how many outlets the pump will serve. The 180 L/h rating in the title is the flow with little resistance; every metre of tubing, every air stone and every centimetre of water depth takes a share of it. A pump with some spare capacity can run an air stone and a sponge filter together, or supply two small tanks through a splitter.

Small aquarium pumps of this type normally work on the diaphragm principle, so they need no oil and little maintenance beyond occasionally replacing the diaphragm and the intake filter pad. Set the pump on a shelf above the water line, or fit a non-return valve in the line, so water cannot siphon back if the power is cut. Soft feet or a pad under the pump reduce the hum that hard surfaces amplify.

Air pumps also power sponge filters, in which rising bubbles draw water through a foam block colonised by nitrifying bacteria, a simple and gentle filter for school tanks with fry or small invertebrates. For smaller vessels that need less air, the Aerator 150 L/h is the lower-output option in this range.

Uses in the Lab and Classroom

• Aerating a school Aquarium or a pond-animal holding tank
• Driving a sponge filter in tanks with fish fry or small invertebrates
• Supplying air to two small tanks through a splitter valve
• Oxygenating water for tadpoles, snails or small fish kept during a project

Care & Handling

• Replace the intake filter pad when it becomes dusty, since a blocked intake reduces output.
• Check tubing for kinks and brittle sections, especially near connectors.
• Unplug before servicing, and never place the pump where it could fall into water.
• Replace the diaphragm with a matching spare if the output falls or the pump becomes noisy.

Why Choose LabEquip

Schools running class aquaria, college zoology labs and aquaculture trainees choose a pump of this size when one unit must serve a larger tank or two smaller ones. LabEquip lists it in the General Lab Products range; supply voltage and plug type can be confirmed through the contact page.

Frequently Asked Questions

Will a 180 L/h pump suit my aquarium?

For typical classroom tanks it gives comfortable aeration, but the useful flow falls with depth and with the number of air stones. If you plan to feed several outlets or a deep tank, allow some spare capacity or add a second pump.

Why is my air pump making a loud humming noise?

Vibration is transmitted through hard surfaces. Stand the pump on a foam pad, keep it from touching the tank or cabinet walls, and check that the diaphragm is not worn, since a tired diaphragm can rattle.

What is a sponge filter and does it need an air pump?

A sponge filter is a foam block on a tube. Air from the pump rises up the tube and draws water through the foam, where bacteria break down waste. It cannot work without an air supply.

Where should the pump be placed?

Above the level of the water, on a dry, stable surface, with a drip loop in the power cable. If it must sit lower, fit a non-return valve in the airline.

Can the pump run continuously?

Aquarium air pumps are designed for continuous operation, and turning them off at night can let oxygen fall when plants stop photosynthesising. Check it regularly for any change in output or noise.

How do I split the air between two tanks?

Use a gang valve or T-piece with small control taps, run a separate line to each tank, and adjust the taps until both air stones bubble evenly. The deeper tank will need its tap opened further.
