hygger 4W Dual Outlet Aquarium Air Pump

The hygger HG219 is a 4 Watt aquarium air pump with stainless steel dual outlets. hygger lists airflow of up to 95GPH(360L/H) per outlet and a max pressure up to 20Kpa (0.02Mpa), enough for tanks up to 120 Gal. It runs on standard AC 110-120V/60Hz and carries a 1 Year warranty.

Strong for its size

Plenty of output at higher pressure means it can push air deeper and through finer stones than small pumps. That suits tall tanks, larger sponge filters, hydroponic reservoirs and seafood holding tanks, all of which hygger names as uses.

Knob control

Turn the knob clockwise for more air and counterclockwise to reduce or close the airflow. That makes it easy to tune for freshwater fish, saltwater coral or a hydroponic system.

Noise reduction

A double-layer structure, a thickened ABS shell and four shockproof rubber pads keep it to a maximum of 35 dB. It is suitable for living rooms and offices; in a quiet bedroom, set it on a soft pad.

Kit contents

• Dual outlet air pump with 5.9ft power cord
• 2 air stones
• 2 lengths of 4.9ft tubing
• 2 check valves
• User manual

Other sizes

This listing is the 4W model. hygger also sells 7W and 11W versions for bigger systems.

Good pairings

Two outlets can drive a pair of sponge filters such as the hygger double sponge filter. Add extra check valves if you split lines further.

Care

Keep the pump above the water line, replace stones when bubbles coarsen, and clear dust from around the pump body every few months.

If one outlet is not in use, close it with the knob or cap it rather than letting air vent freely. That keeps more pressure on the line you are using and lets the stone or filter on it work at its best.
