The Rena Air 100 is for aquariums up to
20 gallons. The Rena Air 100 was created with noise suppression chambers that
were designed to absorb vibration from air movement. The unit has fitted rubber
feet to also help stop vibration with the surface it is placed on. These new
features help to make the Rena Air 100 extremely quiet. The unit was designed to
be very powerful and can maintain great airflow even in lower depths. The Rena
Air 100 comes with a 3 watt power supply with 6' 7" cord and is UL listed. The
Rena Air 100 has 1 outlet.
