What is a Catch tank?

A catch tank is a container designed to collect and store excess liquids or gases from engines or mechanical systems. It is primarily used to capture blow-by gases or oil mist in engines, helping to improve engine performance and extend its lifespan. By separating contaminants or impurities from being reintroduced into the engine, catch tanks prevent the contamination of engine oil or coolant. They are commonly used in vehicles, particularly race cars and high-performance vehicles, and are also applied in industrial machinery and power generation equipment.

Application of Catch tank

✅ Racing Cars:
In racing cars, where high loads produce significant blow-by gases, catch tanks prevent contaminants from re-entering the engine, maintaining performance during races.
✅ Industrial Machinery:
Used in generators or compressors to separate impurities and prevent machinery degradation.
