Manhole fall prevention fence / Manhole ventilation ring-type blower
Manhole Fall Prevention Fence [SS-Gate] Manhole Ventilation Ring-Type Blower [HAST-e]
You can use a combination of fall prevention barriers during manhole work and a fan that does not interfere with the work.
When working at openings such as manholes, ensuring the safety of workers is crucial. By using the manhole fall prevention fence "SS-Gate," you can prevent workers, tools, and materials from falling or dropping. Additionally, when working inside a manhole, a blower is essential to prevent toxic gas exposure and suffocation accidents. Installing the ring-type blower "HAST-e" at the manhole opening allows for continuous airflow into the manhole. Its design does not require a duct for airflow, keeping the opening always accessible. This blower is very convenient for the ascent and descent of workers, tools, and materials. Typically, the ring-type blower "HAST-e" can only be used with openings of φ600mm on its own, but by combining "SS-Gate" and "HAST-e," the ring-type blower can be used with manhole openings other than φ600mm.

Only as much of a better product as needed, when needed. By eliminating the enormous costs of 'ownership,' we maximize the utility of 'usage.' I am convinced that the most efficient system is 'rental.'
