Diaphragm blowers for small tanks and bins and medium depths
Between the low wattage fish tank sized blowers and side channel blowers for larger aeration requirements are diaphragm type blowers that deliver a suitable pressure and air volume for most small tank operations. We supply the Hailea ACO range and the Waterfall LP ranges, allowing for a variety of air delivery rates.
The 100 watt LP100 is an efficient blower for water depths up to 3m and air flow rates between 80 and 120 liters per minute depending on the water depth.
Waterfall & Resun air pumps like the LP100 quietly deliver a maximum high volume air output of 8400 L/hr (140 litre per minute), which is suitable for large fish and koi ponds and industrial applications like aerobic sewage treatment. It should be housed in a low dust environment, but can withstand light rain and water sprinkling. Dust will prematurely wear the rubber valves & diaphragms and affect airstones, blocking them from the inside.
Installation hint: To increase the life of the rubber diaphragms, the unit must have back pressure.
Also used for: Waste water treatment aeration, deep water septic tank aeration, natural swimming pond aeration, aquaculture pond aeration, commercial and industrial water aeration, bubble baths. It can also be used for air lift water pumping & aeration, aquaponics, hydroponics and aquaculture.
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: 44dB(A)+/- at 3m from air pump, 55dB(A)+/- at 500mm from air pump. A quite room ambient noise level is 30dB(A)+/- Cast aluminium body Voltage/Wattage: 240V / 100W Automatic thermal cut-out overload protection Cable length: 1.5m Max pressure: 0.042 mPa / 0.42 bar / 420 mbar / 6.1 psi Max air output: 8400L/hr (140 Litres/minute) Air pump outlet diameter: 20mm Must be set-up above the water level Important: Rated IPX4 (meaning - Should be placed in a low dust environment but will tolerate rain and light sprinkling) Maximum water depth for placed airstones or air diffuser: 4.0m Supplied with a plastic 33 outlet x 46mm barbed manifold to suit 4mm - 8mm silicon air line Air Pump dimensions: 270mm(L)x200mm(W)x230mm(H) Weight: Air Pump, 6.6kg. Cartoned pump: 7.31kg
The blower case is made of aluminium (ZL-102), so does not corrode easily). It has ribs or vanes designed for efficient heat dissipation during use.
The blower is driven by an electrical magnetic motor that runs in a straight line reciprocal motion to work the diaphragm and produce air aith a significant pressure capacity, ideal for water tank aertion.
The design is oil-free, as no lubrication is needed for 24/7 air delivery.
These air blowers are efficient for air deliver to tanks with water depths up to 4m and for air flow rates to about 200 liters per minute.
Waterfall LP100 range blower curves
There are 4 models in this range, PL20, LP40, LP60 and LP100.
Hailea brand blower curves and models
The Hailea brand is very versatile with over 10 models, with a capacity of up to 4m water depth and air deliver potential of up to 250m3/h.
Industrial uses - small tank aeration
These air blowers are efficient for industrial air delivery to tanks for sewage treatment and other applications. In the below image a manifold is adapted to allow 3 air lines, each delivering 40 lpm via micropore aeration hose.
