Hiblow HP-20 Linear Air Pump (20 L/min)

Description

The Hiblow HP-20 is a Japanese-engineered linear (diaphragm) air pump, trusted worldwide for continuous, oil-free aeration in aquaculture, RAS and biological filtration applications. Its linear drive has no gears, belts or pistons to wear out — just a single vibrating diaphragm assembly — giving it a long service life, low running cost and quiet operation at only 31 dBA.

Rated to move 18 L/min of free air at 9.8 kPa, the HP-20 is well suited to small aquariums, hatchery trays and small tank setups. The rainproof outdoor-rated housing and low power draw of just 17 W make it an efficient, low-maintenance choice for continuous biofilter and pond aeration duty.

• Oil-free linear diaphragm design — no lubrication required
• Rated pressure: 9.8 kPa
• Free-air flow: 18 L/min
• Power consumption: 17 W
• Noise level: 31 dBA
• Weight: 3.2 kg
• Outdoor rainproof housing — suitable for external installation
• Replaceable filter pad and field-serviceable diaphragm kit

Typical applications: RAS biological filtration, pond and tank aeration, hatchery oxygen supply, quarantine and holding systems, and septic/effluent aeration.

Note: pump must be mounted above the liquid surface it is aerating, in a dry, ventilated location, to prevent water back-flow into the pump.
