Aeration Pump – NEW ACO 004

This Resun ACO-004 air pump is built for aquarium owners who need steady aeration in an underwater setup. It delivers 4500 l/h (75 l/min) of air at 0.028 MPa, so it can supply oxygen to the water column in a tank that already runs an aeration line.

Why it matters

• The supplier states that it uses more durable, higher-grade materials than comparable pumps of the same design.
• According to the manufacturer, these materials reduce power consumption while increasing output compared with the previous construction.
• The 58 W motor is rated for continuous operation in aquarium aeration, with a flow rate of 4500 l/h.
• Mounting holes in the housing allow the pump to be screwed to a stable surface.

Specifications

• Power: 58 W
• Air output: 4500 l/h (75 l/min)
• Delivered air pressure: 0.028 MPa
• Dimensions: 180 x 100 x 120 mm

What it works with

The pump is designed for aquarium use within the Exotic Underwater category, where it fits filtration and aeration setups. The supplier recommends installing it above the water level to prevent water from flowing back into the pump. Its output is well suited to aeration lines feeding air stones or similar diffusers in aquariums.
