Hiblow HP-40 Linear Air Pump (40 L/min)

Description

The Hiblow HP-40 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 32 dBA.

Rated to move 40 L/min of free air at 12.8 kPa, the HP-40 is well suited to small RAS systems, hatchery tanks and backyard pond aeration. The rainproof outdoor-rated housing and low power draw of just 38 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: 12.8 kPa
• Free-air flow: 40 L/min
• Power consumption: 38 W
• Noise level: 32 dBA
• Weight: 5.7 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.
