Inside the ProLake Cabinet

Open the cabinet and you will find everything working in harmony inside a durable, sound-deadening housing. ProLake packs the interior with the components that make this system run cool and quiet.

• Three custom-built compressors instead of mass-produced units
• High-volume cooling fan to keep temperatures down during long runs
• Fully adjustable, brushed aluminum manifold with a 3 to 4 port layout for easy expansion
• Pressure gauge so you can monitor performance at a glance
• 1 inch ASTM certified acoustical sound-deadening foam keeping operation at a quiet 50/60 DB

The ¾ inch thick cabinet measures 40"W x 24"L x 24"T and protects every part from the elements.

Non-Clogging Duraplate Diffusers on the ProLake3 3.9 Electric Aerator System

The diffusers are where the oxygen meets your water, and these are built tough. Each Duraplate™ diffuser is non-clogging and self-cleaning, so you spend less time on maintenance and more time enjoying a clear pond.

• Rugged enough to withstand 500+ lbs of pressure
• Shrouded and protected parts that keep out debris and predators
• Self-cleaning design that resists clogging over time

Diffuser options: Cabinet Only versions ship with no diffusers, while the full systems include 9 Duraplate™ diffusers ready to install.

Flexible Installation With the ProLake Electric Lake Aeration System

Your electrical hook-up does not have to sit right at the water's edge. This setup lets you place the cabinet where power is convenient and still reach the water.

• Install the cabinet up to 4,000 feet away from the pond
• Run a ½ inch PVC line from the cabinet to a remote manifold
• From the remote manifold, airlines run out to the Duraplate™ diffusers

A suggested Level-Aer™ Equipment Pad (30" x 30" x 3", not included) gives the cabinet a stable base, and Alpine™ ½" weighted airline (1/2" ID x 1" OD, not included) carries air down to the diffusers.
