Complete 4-Diffuser Aeration System with 400 ft of EasySet Airline
This PS40 bundle includes the SilentAir™ 3/4 HP compressor, four ProAir 4 weighted membrane diffusers, and 400 feet (122 m) of 3/8 in. EasySet airline, everything you need to aerate ponds up to 4 acres (1.6 ha). EasySet airline is colour-coded, pre-cut to length, and self-weighted, making installation straightforward without additional ballast. The airline simply connects to the manifold and drops to the diffuser positions you select.
ProAir 4 Weighted Membrane Diffuser
Unlike traditional air stones, the ProAir 4 uses a flexible membrane stick that resists cracking and never requires acid washing. An integrated check valve protects the compressor from back-pressure, and the sled-style base keeps the diffuser upright on the pond floor during installation. Non-stick Teflon coating prevents debris accumulation.
