CHARLOTTE, NC – Rosenberg has introduced two new high-efficiency backward curved impellers equipped with integral inlet cones for optimal airflow. The new DKHR Series fans are available in 630 mm and 710 mm sizes and are suitable for a wide range of HVAC and air movement applications.
The 710 mm model DKHR 710-6SH delivers up to 11,500 CFM airflow or static pressure up to 3.4 inches WG. The 630 mm model DKHR 630-6SH can generate up to 7,600 CFM or 2.6 inches of static pressure (460-Volt / 60 Hz / 3-phase).
Their integral inlet cones are perfectly sized to the impellers to prevent airflow loss. This ensures the best possible airflow in any application. Both sizes are available with or without housings for greater design flexibility.
The DKHR 710 features a free-running 8-blade impeller constructed from sea-waterproof aluminum. The inlet cone is made from galvanized sheet steel. The DKHR 630 employs a plastic impeller. The fans are balanced on two levels according to quality class G 2.5, DIN/ISO 1940. Maintenance-free ball bearings are closed on both sides and sealed for life.
Standard external rotor motors are built to protection class IP 44/54. Thermal contacts provide motor protection. All motors are CE, UL and RoHS approved.
Rosenberg backward curved fans are available to meet customer-defined specifications including airflow, power, rotational speeds, noise level, overall dimensions and finish.
