Description
The HRK series of axial fans are designed to deliver maximum air at a minimum noise level. There are generally three type: small, medium and large depending on the propeller size.
Small: HRK – 150 to HRK – 300, air deliveries from 330 to 1800 m3/h.
Medium: HRK – 301 to HRK – 550, air deliveries from 2000 to 11,000 m3/h.
Large: HRK – 600 to HRK – 999, air deliveries from 12,000 to 50,000 m3/h.
