Control unit for ventilation device

摘要

The aeration control system, especially for oxygen enrichment of ecologically contaminated water, takes air (1) from the air compressor (2) through an array of parallel tubes or hoses (S1-S3) to the aerators (B1-B3) for expansion in the water. The air flows are coordinated by shut-off valves (V1-V3) in each tube/hose, controlled in succession allowing overlaps.
