Product catalog summary
Overview: The document provides technical specifications and details for HW Ventilation's centrifugal clutches, specifically designed for fan applications where a gearmotor is directly coupled with the motor shaft. These clutches are engineered to engage gradually, preventing breakage by allowing a smooth start at high RPMs.
Product Specifications:
  • Designed for 12 or 16 blade aluminum hubs with adjustable blade angles between 20° and 50°.
  • Compatible with various blade profiles and materials, including polypropylene, polyamide, ATEX, and aluminum.
Performance and Features:
  • Engagement at 800 RPM with a torque of 146.7 Nm and power output of 49.5 HP (36.9 kW) at 2400 RPM.
  • Average friction coefficient of 0.45 μ.
  • Clutch case made from cast iron with a cationic epoxy electrocoating for excellent corrosion resistance.
  • Lead-free formulation with high resistance to dust, atmospheric agents, and chemicals.
  • No maintenance required, with thorough testing conducted on all clutches.
Models:
  • FRZ#0001: Suitable for 12/16 blade flanges with a max hole Ø35 H7 keyway.
  • FRZ#0002: Coupled with a gearmotor through studs, suitable for flanges with M8 studs int. Ø115.
Drawings and Dimensions: Detailed drawings for models FRZ#0001 and FRZ#0002 are provided, including specifications for cylindrical and conical shafts.
Additional Specifications:
  • Specific gravity of clutch friction material: 2.30 g/cm³.
  • Rubbing pressure range: 5-100 N/cm².
  • Rubbing speed: less than 20 m/s.
Innovative Coating: The clutches feature a cationic epoxy electrocoating that offers excellent corrosion resistance, improved edge coverage, and resistance to chemicals without using heavy metals.

FAN - FERODO CLUTCH SYSTEMS Product specifications HW Ventilation centrifugal clutches are designed for applications in which a gearmotor attached to a fan is directly coupled with the motor shaft and has to start quickly at a high rpm. In these situations, it is recommendable the usage of a clutch that engages the fan gradually, in order to prevent the risk of breakage. Our ferodo clutches are designed to be installed on 12 or 16 blade aluminum hubs. The blade configuration can be decided by the user (i.e. 12-12, 12-8, etc.) and the setting angles are variable and adjustable in the range of...
