Product Description
JAS Series Three-Lobe Roots Blower is an integrated, skid‑mounted positive displacement blower with advanced three‑lobed rotor and internal reflux structure. It features stable performance under high pressure, low pulsation, low noise and high volumetric efficiency, widely used in industrial processes requiring continuous and reliable air/gas supply.
This series is delivered as a complete unit including base frame, motor, inlet filter silencer, discharge silencer, safety valve, check valve, pressure gauge and flexible connector. It is ready for installation and operation, greatly reducing on-site construction and commissioning time.
Key Features
Advanced three-lobe cycloid rotor profile, uniform air supply, low vibration
Internal reflux structure for stable performance under high pressure (49–98kPa)
Complete skid-mounted integrated design, easy installation and commissioning
Multiple sealing structures available for clean air or special gas conveying
High volumetric efficiency, energy-saving, low operating cost
Rugged cast iron structure, long service life, suitable for 24/7 operation
Compact layout, small footprint, easy maintenance
