Pontec PondoAir Complete Pond Air Pump Sets
Weather-resistant aeration kits with airline, diffusers and replacement diaphragms
Pontec PondoAir sets are complete mains-powered aeration packages for garden ponds. Rather than supplying only the pump, each model includes the airline and diffusers required to distribute its output, plus replacement diaphragms for future servicing.
Pond aeration supports fish, aerobic filter bacteria and the breakdown of organic waste. Its value is greatest during warm weather, after heavy feeding, when medication lowers available oxygen, or when a biological filter has a high oxygen demand. It also provides useful surface movement, but an air pump does not replace correctly sized circulation and filtration.

Which size should I choose?
The compact 200 and 450 suit small ponds and shallow diffuser positions. The 900 is suited to a smaller pond and shallower diffuser placement. The 1800 provides four outlets and more depth capability. The 3600 is the strongest of the three, but remains in the up-to-60 l/min filter band; for heavily stocked koi ponds or deep filter chambers, compare higher-output linear diaphragm pumps.
Diffuser condition and airline layout affect the real result. Long narrow airline, tight non-return valves and old blocked stones increase resistance. Keep the route short where possible, use the intended airline bore and make smooth bends. If the pump is above the water level, protect it from weather while keeping its ventilation openings clear. If it is below water level, a suitable non-return valve is essential.
What is supplied?
Each set includes an IP44 pump, outdoor-rated housing, airline, the stated number of diffusers and replacement diaphragm parts. Mount the pump above water level in a well-ventilated position protected from flooding.
Position diffusers to create useful circulation without stirring deep sediment continuously. In winter, a shallow diffuser can help keep a small gas-exchange area open without mixing the coldest deep water through the entire pond. Never break or pour hot water onto ice above fish.
How this range compares
PondoAir offers a convenient complete set. Choose a specialist Evolution Aqua, HIBLOW, Medo or Charles Austen pump where alarm outputs, higher pressure, larger manifolds or continuous commercial duty are required.

Frequently asked questions
Should a pond air pump run continuously?
Continuous operation is common in stocked ponds and biological filtration, especially during warm weather. Adjust the position and output for winter conditions rather than assuming one arrangement suits every season.
Can I use any air stone?
The diffuser must suit the pump’s output, pressure and airline connection. Too little diffuser area can create excessive back pressure; an oversized or deep diffuser may produce weak airflow.
Does more air always mean more oxygen?
Not automatically. Fine bubbles, contact time, circulation and surface movement all matter. Correct distribution is more useful than concentrating the entire output in one unsuitable stone.
Working pressure by model
- PondoAir 200, 450 and 900: 0.15 bar
- PondoAir 1800: 0.25 bar
- PondoAir 3600: 0.30 bar
Choose from both airflow and pressure. Deeper diffusers and restrictive airline layouts need more pressure, while blocked stones and undersized airline can overload any pump.
