  • 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
  • Cable length: 1.5m
  • 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
