Air Powered, venturi type pipe line blowers specifically adapted to API (American Petroleum Institute) flange plates. 

These pipe line blowers are used to blow down pipe lines prior to maintenance and can be adapted to any API flange from 4" to 24".

A Pipe Line Blower is a device used to clear pipelines of debris, water, or other obstructions. It is commonly used in the oil and gas industry to clear pipelines of debris before testing or commissioning, or to remove water or other fluids from pipelines before maintenance or repair work is performed.

A line blower typically consists of a large, high-pressure air compressor and a series of hoses and valves that are used to connect the blower to the pipeline. The blower is then used to blow compressed air through the pipeline, forcing any debris or fluids out of the pipe and into a collection vessel or discharge point.

Line blowers can be used on a wide range of pipelines, including oil and gas pipelines, water pipelines, and sewage pipelines. They are typically operated by trained professionals with experience in pipeline maintenance and repair.
