Resun LP-100 Air Pump (140 L/Min, 100Watt, 0.042 MPa) – Large Ponds, Quiet

The Resun LP-100 is a heavy-duty linear diaphragm air pump built for serious aeration jobs – large koi ponds, fish farms, septic systems and natural swimming ponds. It delivers a powerful 8,400 L/hr (140 L/min) of air output while running remarkably quietly thanks to its electromagnetic linear diaphragm technology.

Housed in a rugged cast aluminium body with automatic thermal cut-out overload protection, the LP-100 is engineered for continuous, long-term operation. It's IPX4 rated, so while it should be sited in a low-dust spot, it will tolerate rain and light sprinkling without issue – making it well suited to outdoor pond and aquaculture installations.

Versatile enough for everything from commercial aquaculture and waste-water treatment to natural swimming ponds and large koi setups, the LP-100 ships with a 33-outlet manifold to feed multiple air stones from a single unit.

Installation tip: To extend the life of the rubber diaphragms, the pump must have back pressure during operation. It should also be installed above the water level, or fitted with a check valve (e.g. Valterra) to prevent back-siphoning.
