The Resun Air Pump LP40 delivers a maximum air output of 3000L/hr (50 litres per minute) with low noise, which is suitable for most fish and koi ponds.

Electromagmetic linear diaphragm technology
Low noise. Decibel levels measured in a quiet room using A-frequency weighting with medium back pressure loading on the pump:
41dB(A)+/- at 3m from air pump, 50dB(A)+/- at 500mm from air pump. A quite room ambient noise level is 30dB(A)+/-
Plastic body
Voltage/Wattage: 240V/35W
Automatic thermal cut-out overload protection
weight: 4.5kg
Max pressure: 30kPa
Max air output: 3000L/hr (50 Litres/minute)
Air pump outlet diameter: 18mm
Must be set-up above the water level
For maximum diaphragm life, the pump must always be run with a back pressure load of approx 12 – 15kPa. This would give a noticeably sweeter sound to the pump hum. This can be created by air diffusers, air stones, in conjunction with a flow control valve if necessary
Supplied with a plastic 12 outlet manifold to suit 4mm silicon air line. Block off outlets not used with a squirt of silicone sealer into the outlet
