  • $1,926.00


Kasco® Robust-Aire™ RA1 are highly efficient, reliable, and durable aeration systems that induce oxygen transfer, beneficial water movement and mixing to ponds up to 1.5 Acres, 8 to 50 feet deep. 

Installation is quick and easy. These systems come complete with everything you need, including all connectors, adapter fittings, weighted aeration tubing, and three options for enclosures.

Base Mount Cabinet
The compressor can be on the ground with access to ventilation from below. The powder-coated aluminum cabinet includes a cooling fan that provides 110 CFM ventilation, acoustical foam, key lock, and 120-V receptacle or a 240-V junction box.  Dimensions are 24" x 18" x 20" H. Base Mount Cabinets ship motor freight only. 

Post Mount Cabinet (PM)
Great choice if the compressor needs to be off the ground. The powder-coated aluminum cabinet includes a cooling fan that provides 110 CFM ventilation, acoustical foam, key lock, and 120-V receptacle or a 240-V junction box. Dimensions are 19" x 12" x 12" H

No Cabinet (NC)
This is desired when installing a compressor in your own structure. A galvanized mounting bracket system is included with each compressor to allow mounting to a floor, wall, or pedestal.  Rubber mounting feet and all hardware are included. A cooling fan and bracket that attaches to the mounting bracket supply direct ventilation of the compressor.
