Robust-AireTM Aeration System Advantages:

  • No electricity in the water:There are no motors or electrical components in the water and no restrictions on swimming, boating, or fishing while the unit is operating.
  • Easy to maintain: Most maintenance and inspection is performed from shore at the compressor enclosure.
  • Energy efficient operation: Robust-Aire circulates the most water with the least energy expended. Our compressors are energy efficient and Robust-AireTM diffusers produce a superior amount of water flow, exceeding other models by 10 to 40 percent.*
  • Remote installation:Electrical access near the pond may not be feasible or you simply may want to locate the system away from the pond setting. Air can be delivered to the system from 1/4 mile away.
  • Manufactured by Kasco Marine:Known for manufacturing high-quality, energy-efficient water management equipment for over 45+ years, Kasco Marine is a name you can trust.
  • Robust-AireTM Diffusers:are the most efficient on the market and create more water flow to aerate your pond. Diffusers are designed to provide a fine air bubble with the least amount of pressure. The base is made of durable plastic and an open port allows filling with gravel to settle. It has a raised design that keeps the diffusers performing at an optimal level above the pond bottom. A durable, bolted, strain relief attachment ensures that the weighted tubing will not become detached during installation or maintenance.

A large base mount cabinet is included as the default method for the system.

Compressor is mounted in the keyed, lockable cabinet.
Cooling fans provide 110 CFM ventilation per compressor
120 volt receptacle or a 240 volt junction box.
Dimensions are 24” x 18” x 20” H.

Post mounted cabinet (PM) is mountable on an exterior wall or wooden post.

Dimensions 19”x12”x12”H.
120 Volt receptacle or a 240 volt junction box. A single cooling fan provides 110 CFM ventilation. Compressor is mounted at the factory in the cabinet which is provided with acoustical foam and a keyed cabinet lock.
SureSinkTM UV resistant weighted tubing with a lifespan of at least 15 years is available in easy-to-handle 100 foot coils. Each diffuser assembly includes 100 feet of 3/8” tubing for each diffuser. Each coil is boxed and includes our full packet of barbed connectors and adapter fittings, and all-stainless steel tubing clamps. Additional 3/8” or 5/8” SureSinkTM and non-weighted tubing are available to customize your system. Self sinking hose is a real time saver and will actually save you money on your installs over non-weighted tubing that requires brick and cable ties.

Each system includes 100 feet per diffuser of 3/8” tubing, a $116.50 value.  If more SureSink tubing is desired, simply subtract $116.50 for each 100' from the price and add back the price of the desired length of tubing.  For tubing lengths over 300 feet for one diffuser run, use 5/8” Sure Sink tubing for that diffuser run.
