6-30 Series / High-Pressure Process Air
6-30 High-Pressure Centrifugal Fan
6-30 is a high-pressure centrifugal fan designed for industrial process-air and pneumatic conveying duties requiring relatively high pressure with moderate airflow. Typical applications include grain, cotton and material-processing systems, equipment air supply and other high-resistance air-handling duties.

Technical Index
01 / Engineering Overview
High Pressure for Process Air and Material Conveying
The 6-30 series is designed for operating conditions requiring more pressure than ordinary general-purpose ventilation fans. Its performance range extends from compact No.5 configurations to larger No.9 belt-driven units.
The series is particularly suited to pneumatic conveying and concentrated industrial process-air systems where duct resistance and equipment pressure loss are more important than very large room-ventilation airflow.
02 / Application Position
Typical High-Resistance Air-Handling Duties
Pneumatic Conveying
Air delivery for grain, cotton and selected powder or granular material conveying systems.
Process Air
Forced-air supply to industrial equipment requiring higher available pressure.
High-Resistance Ducting
Systems with longer ducts, equipment losses or restrictive process components.
Industrial Air Supply
Clean-air handling where the process requires more pressure than standard ventilation fans provide.
03 / Construction
Single-Inlet Centrifugal Configuration
01
Impeller
Welded steel centrifugal impeller designed for high-pressure process-air duty.
02
Spiral Casing
Welded volute casing converts impeller velocity into useful discharge pressure.
03
Inlet
Converging inlet arrangement guides air into the impeller with reduced entry loss.
04
Drive Options
A-type direct-drive versions and C-type belt-drive versions are available across the series.

Reference catalog values are for preliminary model screening. Final airflow, pressure, shaft power and motor selection must be confirmed against the actual operating point and supplied configuration.
05 / Drive Arrangement
A-Type and C-Type Configurations
A Type
Direct Drive
Compact arrangement used on No.5 and No.6 configurations with direct motor-driven impeller.
C Type
Belt Drive
Separate shaft and belt transmission allow multiple operating speeds and larger fan sizes.
06 / Gas & Material Conditions
Confirm the Medium Before Selection
Clean Air
Suitable for industrial air delivery under compatible gas conditions.
Material Conveying
Confirm conveyed material type, concentration and whether the material passes through the fan or only through the air stream.
Corrosive Gas
Requires separate material and corrosion-resistance review.
Hot / Hazardous Gas
Temperature and explosion-protection requirements must be specified separately.
