Product Details
Product photographs of the Two Stage Regenerative Blower document the 2XGB 720HH37, a high-output unit delivering nearly double the pressure of single-stage alternatives from a compact footprint. Real-shot images present the complete blower with its aviation-grade aluminum alloy shell, deep radial cooling fin pattern, and threaded flange air ports from multiple viewing directions. Internal structure cutaways reveal the two series-mounted side-channel impellers - the regenerative air multiplication principle clearly visible in the blade-to-housing clearance that maintains oil-free output. The high-purity cathode copper coil motor, precision C&U bearings with full-seal rubber rings, and the gasket-isolated pump chamber seal are all documented in cross-section photographs. Material close-up images focus on the aluminum casting surface quality, the junction box terminal block configuration, the silencer pipe's sound-absorbing sponge liner, and the heavy-duty steel base plate. The performance data sheet lists 320 cubic meters per hour airflow, -360 mbar vacuum, and 380 mbar discharge pressure at 50Hz from a 4.3 kW motor. Application photographs show tunnel and underground ventilation, toxic gas extraction in confined construction sites, and document delivery air-tube systems. The Two Stage Regenerative Blower provides high-pressure oil-free air for heavy industrial and civil engineering environments.

Application scenarios introduction
Working in enclosed sites like tunnels or underground foundations presents severe air quality risks. Our vortex blowers are the professional choice for the "removal of toxic gas and local dust" from these cramped work zones. By supplying fresh air while simultaneously extracting drilling dust and smoke, the blower ensures that personnel can breathe safely in high-risk zones. The dual-mode function also powers "fast document delivery" through site-specific air-tubes, streamlining logistics for large-scale engineering projects. With a heavy-duty shock-proof base and impact-resistant housing, the blower is built to withstand the rough handling of construction sites, providing a certified safety solution for global civil engineering firms.
