Inlet/Outlet Flange is a standardized mechanical interface component used to connect exhaust fans/blowers to ductwork or piping systems, ensuring secure, leak-proof connections for airflow management.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Pressure Rating | PN10 to PN40 (or Class 150 to 300) | |
| Flange Thickness | 10mm to 30mm | |
| Sealing Face Type | Raised face (RF), flat face (FF), or ring-type joint (RTJ) | |
| Temperature Range | -20°C to 400°C (varies by material) | |
| Bolt Hole Quantity | 4 to 16 holes (depending on size) | |
| Bolt Circle Diameter | Standardized per flange size (e.g., 100mm to 500mm) |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is used in the following industrial products
A mechanical device that moves air or gases out of an enclosed space to maintain air quality, remove contaminants, or control temperature.
A mechanical device that removes moist air, fumes, or contaminants from an enclosed space by creating airflow.
A chamber within a silencer containing baffles that disrupt and absorb sound waves to reduce noise.
A practical evidence checklist for RFQ preparation and supplier evaluation.

Manufacturer profiles associated with Inlet/Outlet Flange.
Explore company information and manufacturing capabilities, then discuss the scope of your project with a relevant supplier.
Inlet flanges connect to the suction side of the fan (air intake), while outlet flanges connect to the discharge side (air exhaust). They are often identical in design but must be oriented correctly to match airflow direction and system layout.
Match the flange to the fan's port size, pressure rating, and material compatibility. Consider operational temperature, medium (e.g., corrosive gases), and standards (e.g., ISO, DIN). Always use appropriate gaskets and bolts per manufacturer specifications.
