The Resun Air Pump LP20 delivers with low noise a maximum air output of 1320L/hr (22 litres per minute), which is suitable for the smaller 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:
39dB(A)+/- at 3m from air pump, 44dB(A)+/- at 500mm from air pump. A quite room ambient noise level is 30dB(A)+/- - Plastic body
- Voltage/Wattage: 240V / 17W
- Automatic thermal cut-out overload protection
- Cable length: 1.5m
- Max pressure: 28kPa
- Max air output: 1320L/hr (22 Litres/minute)
- Air pump outlet diameter: 16mm
- Must be set-up above the water level
- Maximum water depth for placed airstones or air diffuser: 2.2m
- For maximum diaphragm life, the pump must always be run with a back pressure load of approx 11 - 14kPa. This would give a noticeably sweeter sound to the pump hum. This can be created by air diffusers or air stones, in conjunction with a flow control valve if necessary
- Supplied with a plastic 6 outlet manifold to suit 4mm silicon air line. Block off outlets not used with a squirt of silicone sealer into the outlet
- Air Pump dimensions: 205mm(L) x 145mm(W) x 165mm(H)
