Hidom HD-601 Single Outlet Air Pump

Hidom HD-601 Air Pump UK: Quiet Single Outlet Pump for Culture Vessels, Hatcheries and Small Tanks

Your culture has gone flat, the hatchery is not turning over, or the old pump on the fish room shelf has started to rattle.

Air is what keeps a live culture in suspension and a hatch of brine shrimp alive. When the pump is too weak, or so noisy it gets switched off at night, cultures settle, crash and have to be started again.

The Hidom HD-601 is a compact single outlet air pump that delivers 1.8 litres of air a minute on just 2 watts. It has rubber feet to keep it quiet, a mounting ring for fixing inside a cabinet, and a UK plug fitted. It suits marine and freshwater use.

Picture a steady stream of bubbles rolling a deep green culture, day and night, without you hearing it from the next room.

I have been culturing live marine food in Wales since 2008, with 18+ years in marine aquaculture, and I am happy to advise on setting up air for a culture.

Give your culture the steady air it needs to keep going.

Hidom HD-601 Air Pump: What It Is

The HD-601 is a small diaphragm air pump with one outlet. It sits outside the tank or culture vessel and pushes air down a length of airline to an air stone, a rigid air tube or an air driven filter. It is not submersible. At 100 x 55 x 87mm it takes up very little shelf space, and at 2 watts it costs very little to leave running around the clock, which is exactly how an air pump on a culture needs to be run.

Specification

Power is 2.0 watts. Air output is 1.8 litres per minute at a pressure of 0.012 MPa. There is one outlet, and the output is fixed, not adjustable. The pump measures 100 x 55 x 87mm, has rubber feet and a mounting ring, and comes with a UK plug.

What the HD-601 Is Good For

One outlet at 1.8 litres a minute is a good match for a single culture vessel, whether that is phytoplankton, rotifers or copepods, where you want gentle, constant movement and not a rolling boil. It also suits a brine shrimp hatchery, a small air driven sponge filter in a fry or quarantine tank, or an air stone in a small aquarium. If you need to run several vessels or a deep tank from one pump, you will want something larger.

Setting It Up

Place the pump above the water level of the vessel it is feeding, or fit a check valve in the airline. If the power goes off, water can siphon back down the airline into a pump that sits below the water line, and a check valve stops that. Because the output is fixed, an air valve in the line lets you turn the flow down for a delicate culture. Stand the pump on its rubber feet on a solid surface. Most of the noise from any air pump comes from it vibrating against a shelf or the side of a cabinet.

The pump comes on its own. Air stones, airline, valves and the Air Driven Double Sponge Filter are sold separately.

The HD-601 and Our Culture Kits

If you are starting from scratch, our Copepod Culture Kit, Rotifer Culture Kit and Phytoplankton Culture Kit are all available with an air pump included. The HD-601 on its own is for keepers who already have a vessel and need air for it, want a second culture running alongside the first, or need to replace a pump that has worn out.

Hidom HD-601 FAQ

Is it quiet?

It is a low powered pump with rubber feet to absorb vibration, so it is quiet in normal use. Keeping it on a solid surface and not touching the cabinet wall makes the biggest difference.

Can I use it on a marine tank?

Yes. It is suitable for marine and freshwater use. The pump itself must stay dry and outside the tank.

Can I adjust the air flow?

Not on the pump. Fit an air valve in the airline if you want to turn the flow down.

Do I need a check valve?

If the pump sits below the water level, yes. It stops water siphoning back into the pump if the power fails.

Does it come with airline and an air stone?

No. The pump comes on its own, with a UK plug fitted.
