The Penn-Plax Bubble Bug Aquarium Air Pump provides high performance in a small compact design. This air pump has been acoustically designed for ultra-quiet operation; the powerful motor is encased in a specially designed noise cancelling cover. The non-skid rubber feet keep the air pump in place and offer even more noise dampening. Pump fits comfortably in even the tightest aquarium cabinets and has fun, eye catching bug shape in bright yellow and green color that will blend in with your aquarium décor. Bubble Bug Aquarium Air Pump is suitable for fish tanks up to 38 liters and uses any standard 220V 2-PIN outlet.
