Mixed-Flow مروحة مضمنة
A compact tubular fan that combines axial entry with centrifugal pressure development, then straightens the discharge flow for efficient installation in straight duct runs.
- Compact Mixed-Flow Impeller
- External Motor Arrangement
- Integrated Flow Straighteners
- Straight-Through Duct Layout
مقدمة المنتج
The mixed-flow inline fan places a conical mixed-flow impeller and stationary guide vanes inside a rigid circular housing. Air enters along the fan axis, gains both axial velocity and radial pressure through the impeller, and passes through straightening vanes before leaving the discharge flange. Positioning the motor and drive components outside the primary airstream improves access and protects them from hot or contaminated exhaust while retaining the space-saving advantages of an inline unit.
الخصائص الرئيسية
Downstream guide vanes recover swirl energy and deliver a more uniform velocity profile to the connected duct.
An external motor base keeps electrical and drive components away from the primary airstream and within easy service reach.
Rolled flanges and a welded tubular frame allow horizontal or vertical mounting between standard circular duct sections.
مخاوف المنتج للعملاء
Space-limited duct systems often need more pressure than an axial fan can provide but cannot accommodate the turning space of a conventional centrifugal scroll.
A large scroll fan cannot fit into a straight mechanical-room duct route.The tubular mixed-flow design installs directly in line with the duct while developing useful centrifugal pressure.
Swirling discharge from a compact fan produces noise and uneven readings at downstream sensors.Fixed straightening vanes reduce rotational velocity and improve the airflow profile leaving the fan.
A motor located inside warm or contaminated exhaust air is difficult to inspect and cool.The external motor arrangement separates the drive from the primary air path and provides direct plant-side access.
Rigidly connected inline fans transmit vibration along long metal duct runs.Flexible connectors and external spring isolators decouple the flanged fan casing from adjacent duct sections.
