AQUASMITH Single Outlet Aquarium Air Pump

The AQUASMITH 1.5W-S is a single outlet air pump for fish tanks of 20-40 gallons. It delivers 29GPH at 14Kpa on just 1.5w. Its transparent body shows the floating motor inside, and it pairs a 5mm ABS shell with anti-vibration pads for operation under 30dB.

Quiet by design

A floating motor isolates vibration from the case, and the thick shell damps the hum. AQUASMITH says it runs quieter than water flow, which makes it a fit for bedroom tanks and light sleepers.

Adjustable airflow

A knob sets the air output. Turn it down for gentle bubbles in a betta or shrimp tank, or up to drive a small sponge filter.

A family of models

This listing is the 29GPH single outlet model. AQUASMITH also makes 16, 57 and 80GPH models in single or double outlet versions, covering 2-80 gallon aquariums. Pick the size by your tank and how many lines you need.

What comes with it

The kit includes nano air stones, check valves and silicone tubing, plus a visual guide for a quick setup.

Setup in a few steps

• Place the pump above the waterline on a level surface.
• Connect the tubing with the check valve arrow toward the tank.
• Drop the air stone in and adjust the knob.

Who it suits

A single outlet is ideal for one sponge filter or one air stone in a mid-size tank. If you need two lines, consider the AQUANEAT dual outlet pump. For a tiny desk tank, the NICREW nano pump is smaller still.

Care

Replace the air stone when bubbles grow large and uneven, and keep tubing soft and clean.

Because it draws so little power, it is also a good backup to keep on hand for a hospital tank or for moving fish, where steady aeration matters most.
